這篇教程將從ssm整合shiro的方式出發，以實戰的角度快速的搭建起整個工程的框架，因此重點在與怎麼整合shiro,至於邏輯代碼不是這篇教程的重點。

- 主要代碼
首先配置web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-*.xml</param-value>
</context-param>
<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
配置spring-servlet.xml(同web.xml在同一級目錄下)
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!--這裏主要配置securityManager中的緩存管理、認證策略、加密方式-->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">

<ref bean="secondRealm"/>
</list>
</property>
<!--配置記住我相關的功能-->
<property name="rememberMeManager.cookie.maxAge" value="10"></property>
</bean>
<!--緩存管理-->
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<property name="cacheManagerConfigFile" value="classpath:ehcache.xml"/>
</bean>
<!--認證相關的設置-->

<property name="hashIterations" value="1024"></property>

</bean>
<!--配置bean的生命週期，可以自定義的來調用配置在Spring IOC容器中的shiro bean的生民工週期方法-->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
<!--啓用IOC容器中使用shiro的註解，但必須在配置了lifecycleBeanPostProcessor之後才能使用-->

<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

<property name="securityManager" ref="securityManager"/>
<property name="loginUrl" value="/login.jsp"/>
<property name="successUrl" value="/list.jsp"/>
<property name="unauthorizedUrl" value="/unauthorized.jsp"/>
<!--設置相關頁面的權限

->
<property name="filterChainDefinitions">
<value>
/login.jsp = anon
/shiro/login = anon
/shiro/logout = logout
/user.jsp = roles[user]
/list.jsp = roles[admin]
/** = authc
</value>
</property>
</bean>
<bean id="filterChainDefinitionMap"
factory-bean="filterChainDefinitionMapBuilder" factory-method="buildFilterChainDefintionMap"/>
<!--通過配置bean的方法來增加相關的權限-->
<bean id="filterChainDefinitionMapBuilder"

<bean id="shiroService" class="com.kkcl.shiro.service.ShiroService"/>
</bean>
- 項目部署
啓動項目後默認加載到登陸頁面在登陸頁面中輸入用戶名和密碼
進入LoginController.java的/shiro/login方法
@RequestMapping("/login")
public String login(@RequestParam("username") String username, @RequestParam("password") String password){
Subject subject = SecurityUtils.getSubject();
if(!subject.isAuthenticated()){
UsernamePasswordToken token = new UsernamePasswordToken(username,password);
token.setRememberMe(true);
try {
System.out.println("====================");
System.out.println("1."+token.hashCode());
subject.login(token);
} catch (AuthenticationException e) {
System.out.println("登陸失敗："+ e.getMessage());
}
}
return "redirect:/list.jsp";
}
程序運行到subject.login(token);進入編寫好的ShiroRealm.java和SecondRealm.java
由於ShiroRealm和SecondRealm的代碼相識，故這裏之戰是SecondRealm中打主要代碼
public class SecondRealm extends AuthenticatingRealm {
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
/**
System.out.println("====================");
System.out.println("doGetAuthenticationInfo:"+token.hashCode());
System.out.println("====================");
return null;
**/
System.out.println("[SecondRealm] doGetAuthenticationInfo:"+token.hashCode());
UsernamePasswordToken upToken = (UsernamePasswordToken)token;
String username = upToken.getUsername();
//調用數據庫的方法，從數據中查詢username對應的用戶記錄
System.out.println("從數據庫中共獲取到username:"+username +"所對應的用戶信息");
if("unknow".equals(username)){
throw new UnknownAccountException("用戶不存在！");
}
if("monster".equals(username)){
throw new LockedAccountException("該用戶已被鎖定！");
}
//principal認證的實體的相關的信息，可以是username,也可以是數據庫表對應的用戶的實體類的對象
Object principal = username;
//憑證(密碼)
Object credentials = "123456";
if("admin".equals(username)){
credentials = "0d414ed7ade260fc506cbf4628041b4c17fe8f32";
}else if("user".equals(username)){
credentials = "073d4c3ae812935f23cb3f2a71943f49e082a718";
}
//當前realm的名稱
String realmName = getName();
//鹽值加密
ByteSource byteSourceSalt = ByteSource.Util.bytes(username);
SimpleAuthenticationInfo info = null;
info = new SimpleAuthenticationInfo(principal,credentials,byteSourceSalt,realmName);
return info;
}
}
如何符合相關的認證的規則，將成功的跳轉到list.jsp頁面，認證不通過時將跳轉回login.jsp頁面。
