Apache Shiro是Java的一個安全框架。目前,使用Apache Shiro的人越來越多,因爲它相當簡單,對比Spring Security,可能沒有Spring Security做的功能強大,但是在實際工作時可能並不需要那麼複雜的東西,所以使用小而簡單的Shiro就足夠了。
因爲我總結的是使用SpringMVC和Apache Shiro整合,注重的是整合和使用,至於基礎,我這裏就不細說了.按照慣例,既然是需要創建項目,那麼我們首先需要JAR包,Apache shiro的架包除了除了基本的以外,我們還需要shiro-web和shiro-spring的的架包,下面是所需要的所有shiro架包,至於其他的架包,像緩存的架包,Spring和SpringMVC的架包還是和我們以前使用的架包一樣的。
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-core</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-ehcache</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-web</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.2.3</version> </dependency>
所有的架包都搞清楚了以後,我們就可以開始正式搭建了,在myeclise中創建一個maven項目,將需要的架包信息依賴全部放入。下面就分步驟來創建
1.首先創建spring的配置文件,位置都在在resource中,配置文件是spring-context.xml,創建Apache Shiro的配置文件,名字是spring-context-shiro.xml,還有一個配置文件是springmvc的,配置文件是spring-mvc,這樣起名是有原因的,因爲這樣我們就可以在web.xml中設置配置文件的時候,直接使用通配符了:
<!-- 配置spring容器的路徑 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:/spring-context-*.xml</param-value> </context-param> <!-- 對spring開始監聽 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
這樣就可以掃描到兩個配置文件了,又不會掃描到我們的spring-mvc.xml了,
2除了在web.xml中設置這個以外,我們還需要設置spring-mvc的位置:
<!-- MVC Servlet 設置springmvc的Servlet --> <servlet> <servlet-name>springServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
3.在web.xml中配置shiroFilter:
<filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
注意,這個shiroFilter名稱,後面的配置還需要使用到,所以要注意咯。
4,因爲shiro的session是自己實現的,所以我們還需要一個緩存框架,所以在spring的配置文件一定要注意配置哦,
<!-- 緩存 --> <bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"> <property name="configLocation" value="classpath:${ehcache.file}"></property> </bean>
spring的其他的配置,該怎樣還是這樣,我們的重點是配置spring-context-shiro.xml:先把配置的貼出來,然後講一下這幾個配置的意義:
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd" default-lazy-init="true"> <description>Shiro Configuration</description> <!-- 加載配置屬性文件 --> <context:property-placeholder ignore-unresolvable="true" location="classpath:yonyou.properties" /> <!-- Shiro權限過濾過濾器定義 --> <bean name="shiroFilterChainDefinitions" class="java.lang.String"> <constructor-arg> <value> /static/** = anon /userfiles/** = anon ${adminPath}/cas = cas ${adminPath}/login = authc ${adminPath}/logout = logout ${adminPath}/** = user </value> </constructor-arg> </bean> <!-- 安全認證過濾器 --> <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean"> <property name="securityManager" ref="securityManager" /><!-- <property name="loginUrl" value="${cas.server.url}?service=${cas.project.url}${adminPath}/cas" /> --> <property name="loginUrl" value="${adminPath}/login" /> <property name="successUrl" value="${adminPath}?login" /> <property name="filters"> <map> <entry key="cas" value-ref="casFilter"/> <entry key="authc" value-ref="formAuthenticationFilter"/> </map> </property> <property name="filterChainDefinitions"> <ref bean="shiroFilterChainDefinitions"/> </property> </bean> <!-- CAS認證過濾器 --> <bean id="casFilter" class="org.apache.shiro.cas.CasFilter"> <property name="failureUrl" value="${adminPath}/login"/> </bean> <!-- 定義Shiro安全管理配置 --> <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager"> <property name="realm" ref="systemAuthorizingRealm" /> <property name="sessionManager" ref="sessionManager" /> <property name="cacheManager" ref="shiroCacheManager" /> </bean> <!-- 自定義會話管理配置 --> <bean id="sessionManager" class="com.yonyou.hotusm.common.security.session.SessionManager"> <property name="sessionDAO" ref="sessionDAO"/> <!-- 會話超時時間,單位:毫秒 --> <property name="globalSessionTimeout" value="${session.sessionTimeout}"/> <!-- 定時清理失效會話, 清理用戶直接關閉瀏覽器造成的孤立會話 --> <property name="sessionValidationInterval" value="${session.sessionTimeoutClean}"/><!-- <property name="sessionValidationSchedulerEnabled" value="false"/> --> <property name="sessionValidationSchedulerEnabled" value="true"/> <property name="sessionIdCookie" ref="sessionIdCookie"/> <property name="sessionIdCookieEnabled" value="true"/> </bean> <!-- 指定本系統SESSIONID, 默認爲: JSESSIONID 問題: 與SERVLET容器名衝突, 如JETTY, TOMCAT 等默認JSESSIONID, 當跳出SHIRO SERVLET時如ERROR-PAGE容器會爲JSESSIONID重新分配值導致登錄會話丟失! --> <bean id="sessionIdCookie" class="org.apache.shiro.web.servlet.SimpleCookie"> <constructor-arg name="name" value="jeesite.session.id"/> </bean> <!-- 自定義Session存儲容器 --><!-- <bean id="sessionDAO" class="com.yonyou.hotusm.common.security.shiro.session.JedisSessionDAO"> --><!-- <property name="sessionIdGenerator" ref="idGen" /> --><!-- <property name="sessionKeyPrefix" value="${redis.keyPrefix}_session_" /> --><!-- </bean> --> <bean id="sessionDAO" class="com.yonyou.hotusm.common.security.session.CacheSessionDAO"> <property name="sessionIdGenerator" ref="idGen" /> <property name="activeSessionsCacheName" value="activeSessionsCache" /> <property name="cacheManager" ref="shiroCacheManager" /> </bean> <!-- 定義授權緩存管理器 --><!-- <bean id="shiroCacheManager" class="com.thinkgem.jeesite.common.security.shiro.cache.SessionCacheManager" /> --> <bean id="shiroCacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> <property name="cacheManager" ref="cacheManager"/> </bean> <!-- 保證實現了Shiro內部lifecycle函數的bean執行 --> <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/> <!-- AOP式方法級權限檢查 --> <bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor"> <property name="proxyTargetClass" value="true" /> </bean> <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"> <property name="securityManager" ref="securityManager"/> </bean> </beans>
ecurityManager:是shiro最重要的一個對象,授權和驗證都是由它來做的,下面就一一的來講他的依賴類,
一:realm:域,Shiro從從Realm獲取安全數據(如用戶、角色、權限),就是說SecurityManager要驗證用戶身份,那麼它需要從Realm獲取相應的用戶進行比較以確定用戶身份是否合法;也需要從Realm得到用戶相應的角色/權限進行驗證用戶是否能進行操作;可以把Realm看成DataSource,即安全數據源。下對於源代碼,我就不細細的研究了,下面是我重寫的realm,:
package com.yonyou.hotusm.module.sys.security; import java.io.Serializable; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authc.SimpleAuthenticationInfo; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.authz.UnauthenticatedException; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.subject.PrincipalCollection; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.yonyou.hotusm.module.sys.dao.UserDao; import com.yonyou.hotusm.module.sys.entity.User; import com.yonyou.hotusm.module.sys.util.UserUtils; @Service public class SystemAuthorizingRealm extends AuthorizingRealm { @Autowired private UserDao userDao; @Override protected AuthorizationInfo doGetAuthorizationInfo( PrincipalCollection principals) { SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); info.addStringPermission("sys:manager"); info.addStringPermission("user"); System.out.println("開始授權"); return info; } @Override protected AuthenticationInfo doGetAuthenticationInfo( AuthenticationToken token) throws AuthenticationException { UsernamePasswordToken upToken = (UsernamePasswordToken) token; String username = upToken.getUsername(); String password = new String(upToken.getPassword()); User user = new User(); user.setLoginName(username); user = userDao.get(user); System.out.println("==========="); if (user != null) { if (user.getPassword().equals(password)) { return new SimpleAuthenticationInfo(username, password, getName()); } } throw new UnauthenticatedException(); } public static class Principal implements Serializable { private static final long serialVersionUID = 1L; private String id; // 編號 private String loginName; // 登錄名 private String name; // 姓名 public Principal(User user) { this.id = user.getId(); this.loginName = user.getLoginName(); this.name = user.getName(); } public String getId() { return id; } public String getLoginName() { return loginName; } public String getName() { return name; } /** * * 獲取SESSIONID */ public String getSessionid() { try { return (String) UserUtils.getSession().getId(); } catch (Exception e) { return ""; } } @Override public String toString() { return id; } } }
看的出來,其中最重要的是doGetAuthorizationInfo和doGetAuthenticationInfo,這兩個方法,doGetAuthorizationInfo是對當前的用戶進行授權的,至於授權的時期,就是當用戶需要驗證的時候,我這裏只是簡單的寫死了,但是在實際項目開發中,我們一般會將權限存放在數據表中,所以真實情況是先到數據庫中查出一個集合,然後迭代授權,
doGetAuthenticationInfo對於的是對用戶驗證,這裏我們就需要從數據庫中根據用戶查出用戶,根據用戶情況,拋出不用的異常。
下面就是講解sessionManager,因爲Shiro有自己的一套session體系,有sessionManager就不奇怪了,sessionManager主要職責是管理session的創建和刪除,特別提一下,sessionManager對session的操作,其實只是調用了sessionDAO,然再加上自己的一些操作,所以,我們可以看到sessionManager的bean還依賴sessionDAO,下面是自己實現的sessionManager:
package com.yonyou.hotsum.common.security.shiro.session; import java.io.Serializable; import java.util.Collection; import java.util.Date; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.shiro.session.InvalidSessionException; import org.apache.shiro.session.Session; import org.apache.shiro.session.UnknownSessionException; import org.apache.shiro.session.mgt.SessionContext; import org.apache.shiro.session.mgt.SessionKey; import org.apache.shiro.session.mgt.SimpleSession; import org.apache.shiro.web.servlet.Cookie; import org.apache.shiro.web.servlet.ShiroHttpServletRequest; import org.apache.shiro.web.servlet.SimpleCookie; import org.apache.shiro.web.session.mgt.DefaultWebSessionManager; import org.apache.shiro.web.util.WebUtils; /** * * 自定義WEB會話管理類 * * @author hotusm * * */ public class SessionManager extends DefaultWebSessionManager { public SessionManager() { super(); } @Override protected Serializable getSessionId(ServletRequest request, ServletResponse response) { // 如果參數中包含“__sid”參數,則使用此sid會話。 // 例如:http://localhost/project?__sid=xxx&__cookie=true String sid = request.getParameter("__sid"); if (org.apache.commons.lang3.StringUtils.isNotBlank(sid)) { // 是否將sid保存到cookie,瀏覽器模式下使用此參數。 if (WebUtils.isTrue(request, "__cookie")) { HttpServletRequest rq = (HttpServletRequest) request; HttpServletResponse rs = (HttpServletResponse) response; Cookie template = getSessionIdCookie(); Cookie cookie = new SimpleCookie(template); cookie.setValue(sid); cookie.saveTo(rq, rs); } // 設置當前session狀態 request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_SOURCE, ShiroHttpServletRequest.URL_SESSION_ID_SOURCE); // session來源與url request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID, sid); request.setAttribute(ShiroHttpServletRequest.REFERENCED_SESSION_ID_IS_VALID, Boolean.TRUE); return sid; } else { return super.getSessionId(request, response); } } @Override public void validateSessions() { super.validateSessions(); } @Override protected Session retrieveSession(SessionKey sessionKey) { try { return super.retrieveSession(sessionKey); } catch (UnknownSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public Date getStartTimestamp(SessionKey key) { try { return super.getStartTimestamp(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public Date getLastAccessTime(SessionKey key) { try { return super.getLastAccessTime(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public long getTimeout(SessionKey key) { try { return super.getTimeout(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return 0; } } @Override public void setTimeout(SessionKey key, long maxIdleTimeInMillis) { try { super.setTimeout(key, maxIdleTimeInMillis); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 } } @Override public void touch(SessionKey key) { try { super.touch(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 } } @Override public String getHost(SessionKey key) { try { return super.getHost(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public Collection<Object> getAttributeKeys(SessionKey key) { try { return super.getAttributeKeys(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public Object getAttribute(SessionKey sessionKey, Object attributeKey) { try { return super.getAttribute(sessionKey, attributeKey); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public void setAttribute(SessionKey sessionKey, Object attributeKey, Object value) { try { super.setAttribute(sessionKey, attributeKey, value); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 } } @Override public Object removeAttribute(SessionKey sessionKey, Object attributeKey) { try { return super.removeAttribute(sessionKey, attributeKey); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 return null; } } @Override public void stop(SessionKey key) { try { super.stop(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 } } @Override public void checkValid(SessionKey key) { try { super.checkValid(key); } catch (InvalidSessionException e) { // 獲取不到SESSION不拋出異常 } } @Override protected Session doCreateSession(SessionContext context) { try { return super.doCreateSession(context); } catch (IllegalStateException e) { return null; } } @Override protected Session newSessionInstance(SessionContext context) { Session session = super.newSessionInstance(context); session.setTimeout(getGlobalSessionTimeout()); return session; } @Override public Session start(SessionContext context) { try { return super.start(context); } catch (NullPointerException e) { SimpleSession session = new SimpleSession(); session.setId(0); return session; } } }
看代碼就明白,其實就是對session的操作,
還有就是sessionDAO了,這個sessionDAO纔是真正對session操作的bean:
package com.yonyou.hotusm.common.security.shiro.session; import java.io.Serializable;import java.util.Collection;import java.util.Set; import javax.servlet.http.HttpServletRequest; import org.apache.shiro.session.Session;import org.apache.shiro.session.UnknownSessionException;import org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO;import org.apache.shiro.subject.PrincipalCollection;import org.apache.shiro.subject.support.DefaultSubjectContext;import org.slf4j.Logger;import org.slf4j.LoggerFactory; import com.google.common.collect.Sets; import com.yonyou.hotusm.common.config.Global;import com.yonyou.hotusm.common.utils.DateUtils;import com.yonyou.hotusm.common.web.Servlets; /** * 系統安全認證實現類 * @author hotusm * */public class CacheSessionDAO extends EnterpriseCacheSessionDAO implements SessionDAO { private Logger logger = LoggerFactory.getLogger(getClass()); public CacheSessionDAO() { super(); } @Override protected void doUpdate(Session session) { if (session == null || session.getId() == null) { return; } HttpServletRequest request = Servlets.getRequest();if (request != null){ String uri = request.getServletPath();// 如果是靜態文件,則不更新SESSIONif (Servlets.isStaticFile(uri)){return; }// 如果是視圖文件,則不更新SESSIONif (org.apache.commons.lang3.StringUtils.startsWith(uri, Global.getConfig("web.view.prefix")) && org.apache.commons.lang3.StringUtils.endsWith(uri, Global.getConfig("web.view.suffix"))){return; }// 手動控制不更新SESSIONString updateSession = request.getParameter("updateSession");if (Global.FALSE.equals(updateSession) || Global.NO.equals(updateSession)){return; } } super.doUpdate(session); logger.debug("update {} {}", session.getId(), request != null ? request.getRequestURI() : ""); } @Override protected void doDelete(Session session) { if (session == null || session.getId() == null) { return; } super.doDelete(session); logger.debug("delete {} ", session.getId()); } @Override protected Serializable doCreate(Session session) { HttpServletRequest request = Servlets.getRequest();if (request != null){ String uri = request.getServletPath();// 如果是靜態文件,則不創建SESSIONif (Servlets.isStaticFile(uri)){ return null; } }super.doCreate(session); logger.debug("doCreate {} {}", session, request != null ? request.getRequestURI() : ""); return session.getId(); } @Override protected Session doReadSession(Serializable sessionId) {return super.doReadSession(sessionId); } @Override public Session readSession(Serializable sessionId) throws UnknownSessionException { try{ Session s = null; HttpServletRequest request = Servlets.getRequest(); if (request != null){ String uri = request.getServletPath(); // 如果是靜態文件,則不獲取SESSION if (Servlets.isStaticFile(uri)){ return null; } s = (Session)request.getAttribute("session_"+sessionId); } if (s != null){ return s; } Session session = super.readSession(sessionId); logger.debug("readSession {} {}", sessionId, request != null ? request.getRequestURI() : ""); if (request != null && session != null){ request.setAttribute("session_"+sessionId, session); } return session; }catch (UnknownSessionException e) {return null; } } /** * 獲取活動會話 * @param includeLeave 是否包括離線(最後訪問時間大於3分鐘爲離線會話) * @return */@Overridepublic Collection<Session> getActiveSessions(boolean includeLeave) {return getActiveSessions(includeLeave, null, null); } /** * 獲取活動會話 * @param includeLeave 是否包括離線(最後訪問時間大於3分鐘爲離線會話) * @param principal 根據登錄者對象獲取活動會話 * @param filterSession 不爲空,則過濾掉(不包含)這個會話。 * @return */@Overridepublic Collection<Session> getActiveSessions(boolean includeLeave, Object principal, Session filterSession) {// 如果包括離線,並無登錄者條件。if (includeLeave && principal == null){return getActiveSessions(); } Set<Session> sessions = Sets.newHashSet();for (Session session : getActiveSessions()){boolean isActiveSession = false;// 不包括離線並符合最後訪問時間小於等於3分鐘條件。if (includeLeave || DateUtils.pastMinutes(session.getLastAccessTime()) <= 3){ isActiveSession = true; }// 符合登陸者條件。if (principal != null){ PrincipalCollection pc = (PrincipalCollection)session.getAttribute(DefaultSubjectContext.PRINCIPALS_SESSION_KEY);if (principal.toString().equals(pc != null ? pc.getPrimaryPrincipal().toString() : org.apache.commons.lang3.StringUtils.EMPTY)){ isActiveSession = true; } }// 過濾掉的SESSIONif (filterSession != null && filterSession.getId().equals(session.getId())){ isActiveSession = false; }if (isActiveSession){ sessions.add(session); } }return sessions; } }
,看sessionDAO還有一個idGen依賴bean,指的是id的生成策略,這個bean也是自己定義的,但是需要繼承SessionIdGenerator,其中就有public Serializable generateId(Session session),返回的就是session的id,至於shiroCacheManager我們前面已經講過了,就是session的緩存,我們使用的底層是cacheManager.
2,設置完securityManager以後,我們就開始設置shiroFilter,記得前面說過其中的一個配置名字後面還需要使用,就是這個了,其中有loginUrl,配置的就是登陸頁面,登陸失敗以及session失效都會跳到這個頁面,successUrl指的是登陸成功以後,跳轉的頁面,我們需要注意的是,真正的驗證並不是在controller中的,而是我們配置的<entry key="authc" value-ref="formAuthenticationFilter"/>這個filter .既然說到filter 那麼就詳細的講一下這個filter怎麼配置,我們看到在
<property name="filterChainDefinitions"> <ref bean="shiroFilterChainDefinitions"/> </property>
配置了一連串的字符串,這個其實也很好看出來,這些就是制定特定的url進行攔截的,而這些攔截就是使用filter的,而filter就是在
<property name="filters"> <map> <entry key="cas" value-ref="casFilter"/> <entry key="authc" value-ref="formAuthenticationFilter"/> <entry key="outdate" value-ref="sessionOutDateFilter"/> </map> </property>
配置,配置了以後,我們就能在filterChainDefinitions使用這個key了,shiro提供了一部分的filter:
?===============其權限過濾器及配置釋義=======================
anon org.apache.shiro.web.filter.authc.AnonymousFilter
authc org.apache.shiro.web.filter.authc.FormAuthenticationFilter
authcBasic org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter
perms org.apache.shiro.web.filter.authz.PermissionsAuthorizationFilter
port org.apache.shiro.web.filter.authz.PortFilter
rest org.apache.shiro.web.filter.authz.HttpMethodPermissionFilter
roles org.apache.shiro.web.filter.authz.RolesAuthorizationFilter
ssl org.apache.shiro.web.filter.authz.SslFilter
user org.apache.shiro.web.filter.authc.UserFilter
logout org.apache.shiro.web.filter.authc.LogoutFilter
anon:例子/admins/**=anon 沒有參數,表示可以匿名使用。
authc:例如/admins/user/**=authc表示需要認證(登錄)才能使用,沒有參數
roles:例子/admins/user/**=roles[admin],參數可以寫多個,多個時必須加上引號,並且參數之間用逗號分割,當有多個參數時,例如admins/user/**=roles["admin,guest"],每個參數通過纔算通過,相當於hasAllRoles()方法。
perms:例子/admins/user/**=perms[user:add:*],參數可以寫多個,多個時必須加上引號,並且參數之間用逗號分割,例如/admins/user/**=perms["user:add:*,user:modify:*"],當有多個參數時必須每個參數都通過才通過,想當於isPermitedAll()方法。
rest:例子/admins/user/**=rest[user],根據請求的方法,相當於/admins/user/**=perms[user:method] ,其中method爲post,get,delete等。
port:例子/admins/user/**=port[8081],當請求的url的端口不是8081是跳轉到schemal://serverName:8081?queryString,其中schmal是協議http或https等,serverName是你訪問的host,8081是url配置裏port的端口,queryString
是你訪問的url裏的?後面的參數。
authcBasic:例如/admins/user/**=authcBasic沒有參數表示httpBasic認證
ssl:例子/admins/user/**=ssl沒有參數,表示安全的url請求,協議爲https
user:例如/admins/user/**=user沒有參數表示必須存在用戶,當登入操作時不做檢查
當然,我們自己也可以自定義的。像<entry key="outdate" value-ref="sessionOutDateFilter"/>,就是自己定義的,最底層就是過濾器,下面是我實現的一個filter:
package com.thinkgem.jeesite.common.security.shiro.session; import java.io.PrintWriter; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.shiro.web.servlet.AdviceFilter; import com.thinkgem.jeesite.modules.sys.security.SystemAuthorizingRealm.Principal; import com.thinkgem.jeesite.modules.sys.utils.UserUtils; /** * * 自定義filter * * @author Hotusm * */ public class SessionOutDateFilter extends AdviceFilter { private String redirectUrl = "http://10.10.3.118:633/portal/";// session // 失效之後需要跳轉的頁面 private String loginUrl = "/kms/a/login";// 排除這個鏈接 其他的鏈接都會進行攔截 private String frontUrl = "cms/f"; protected boolean preHandle(ServletRequest request, ServletResponse response) { Principal principal = UserUtils.getPrincipal(); HttpServletRequest req = (HttpServletRequest) request; String uri = req.getRequestURI(); if (uri.endsWith(frontUrl) | loginUrl.equals(uri) | (principal != null && !principal.isMobileLogin())) { return true; } try { issueRedirect(request, response, redirectUrl); } catch (Exception e) { e.printStackTrace(); } return false; } protected void issueRedirect(ServletRequest request, ServletResponse response, String redirectUrl) throws Exception { String url = "<a href=" + redirectUrl + " target=\"_blank\" onclick=\"custom_close()\">重新連接<a/> "; HttpServletResponse resp = (HttpServletResponse) response; HttpServletRequest req = (HttpServletRequest) request; response.setContentType("text/html;charset=UTF-8"); PrintWriter out = resp.getWriter(); out.print("<script language='javascript'>"); out.print("function custom_close(){" + "self.opener=null;" + "self.close();}"); out.print("</script>"); out.print("驗證信息出錯,請點擊" + url); } public String getRedirectUrl() { return redirectUrl; } public void setRedirectUrl(String redirectUrl) { this.redirectUrl = redirectUrl; } public String getLoginUrl() { return loginUrl; } public void setLoginUrl(String loginUrl) { this.loginUrl = loginUrl; } }
3.需要注意一點是formAuthenticationFilter是登陸以後,身份驗證的入口,但是隻攔截POST方式的loginUrl,就是我們前面配置的那個url,成功以後會跳到我們配置的那個成功頁面,一般我們都是設置一個虛擬路徑,然後在controller跳轉頁面:

下面是authc對應的那個filter的代碼,
@Service public class FormAuthenticationFilter extends org.apache.shiro.web.filter.authc.FormAuthenticationFilter { public static final String DEFAULT_CAPTCHA_PARAM = "validateCode"; public static final String DEFAULT_MOBILE_PARAM = "mobileLogin"; public static final String DEFAULT_MESSAGE_PARAM = "message"; private String captchaParam = DEFAULT_CAPTCHA_PARAM; private String mobileLoginParam = DEFAULT_MOBILE_PARAM; private String messageParam = DEFAULT_MESSAGE_PARAM; @Autowired private UserDao userDao; @Value("${local_pwd}") private String local_pwd; @Override protected AuthenticationToken createToken(ServletRequest request, ServletResponse response) { String username = getUsername(request); String password = getPassword(request); System.out.println("---------------------------------------"); System.out.println("---------------------------------------"); System.out.println("---------------------------------------"); System.out.println("FomrAuth:username:" + username + " password:" + password + ""); System.out.println("---------------------------------------"); System.out.println("---------------------------------------"); System.out.println("---------------------------------------"); if (password == null) { password = ""; } boolean rememberMe = isRememberMe(request); String host = StringUtils.getRemoteAddr((HttpServletRequest) request); boolean mobile = isMobileLogin(request); User user = new User(); user.setLoginName(username); user = userDao.getByLoginName(user); boolean flag = true; try { if (username.equals("superadmin")) { System.out.println("superadmin"); flag = PLStrategy.get(password, user, "local"); } else { flag = PLStrategy.get(password, user, "nc"); } } catch (UnsupportedEncodingException e) { e.printStackTrace(); } if (flag) { password = local_pwd; } // end return new UsernamePasswordToken(username, password.toCharArray(), rememberMe, host, mobile); // end } public String getCaptchaParam() { return captchaParam; } protected String getCaptcha(ServletRequest request) { return WebUtils.getCleanParam(request, getCaptchaParam()); } public String getMobileLoginParam() { return mobileLoginParam; } protected boolean isMobileLogin(ServletRequest request) { return WebUtils.isTrue(request, getMobileLoginParam()); } public String getMessageParam() { return messageParam; } /** * 登錄成功之後跳轉URL */ @Override public String getSuccessUrl() { return super.getSuccessUrl(); } @Override protected void issueSucce***edirect(ServletRequest request, ServletResponse response) throws Exception { // Principal p = UserUtils.getPrincipal(); // if (p != null && !p.isMobileLogin()){ WebUtils.issueRedirect(request, response, getSuccessUrl(), null, true); // }else{ // super.issueSucce***edirect(request, response); // } } /** * 登錄失敗調用事件 */ @Override protected boolean onLoginFailure(AuthenticationToken token, AuthenticationException e, ServletRequest request, ServletResponse response) { String className = e.getClass().getName(), message = ""; if (IncorrectCredentialsException.class.getName().equals(className) || UnknownAccountException.class.getName().equals(className)) { message = "用戶或密碼錯誤, 請重試."; } else if (e.getMessage() != null && org.apache.commons.lang3.StringUtils.startsWith(e.getMessage(), "msg:")) { message = org.apache.commons.lang3.StringUtils.replace(e.getMessage(), "msg:", ""); } else { message = "系統出現點問題,請稍後再試!"; e.printStackTrace(); // 輸出到控制檯 } request.setAttribute(getFailureKeyAttribute(), className); request.setAttribute(getMessageParam(), message); return true; } }
,經過上面的一些操作,shiro登錄和授權就可以做好了,對於退出,我們只要設置退出按鈕的鏈接地址是我們前面filterChainDefinitions配置DE路徑就可以了,我的是: ${adminPath}/logout = logout;
