Spring mvc+shiro+ehcache整合(詳細配置)
發現最近寫博客寫的少了，正好有時間，把shiro的配置步驟搞上來
本項目是spring mvc整合shiro,用了md5加密，各種配置文件都是從官方例子中拷貝來，註釋比較多，
此項目目前只涉及簡單的登陸驗證。
1.沒用maven，直接貼jar包地址：http://download.csdn.net/detail/java__han/9903446
2.web.xml配置

<!-- =========================================================
Shiro Core Components - Not Spring Specific
========================================================= -->
<!-- Shiro's main business-tier object for web-enabled applications
(use DefaultSecurityManager instead when there is no web environment)-->
<!--
1.配置securityManager
-->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="cacheManager" ref="cacheManager"/>
<property name="realm" ref="jdbcRealm"/>
</bean>
<!-- Let's use some enterprise caching support for better performance. You can replace this with any enterprise
caching framework implementation that you like (Terracotta+Ehcache, Coherence, GigaSpaces, etc -->
<!--
2. 配置cacheManager
-->
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<!-- Set a net.sf.ehcache.CacheManager instance here if you already have one. If not, a new one
will be creaed with a default config:
<property name="cacheManager" ref="ehCacheManager"/> -->
<!-- If you don't have a pre-built net.sf.ehcache.CacheManager instance to inject, but you want
a specific Ehcache configuration to be used, specify that here. If you don't, a default
will be used.:-->
<property name="cacheManagerConfigFile" value="classpath:ehcache.xml"/>
</bean>
<!-- Used by the SecurityManager to access security data (users, roles, etc).
Many other realm implementations can be used too (PropertiesRealm,
LdapRealm, etc. -->
<!--
3.配置realm
3.1直接配置實現了Realm接口的bean
-->
<bean id="jdbcRealm" class="com.hc.shiro.ce.realms.ShiroRealm">
<property name="credentialsMatcher">
<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
<property name="hashAlgorithmName" value="MD5"></property>
<property name="hashIterations" value="1024"></property>
</bean>
</property>
</bean>
<!-- =========================================================
Shiro Spring-specific integration
========================================================= -->
<!-- Post processor that automatically invokes init() and destroy() methods
for Spring-configured Shiro objects so you don't have to
1) specify an init-method and destroy-method attributes for every bean
definition and
2) even know which Shiro objects require these methods to be
called. -->
<!--
4.配置lifecycleBeanPostProcessor。自動調用配置在spring ioc 容器中shiro bean的生命週期方法
-->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>
<!-- Enable Shiro Annotations for Spring-configured beans. Only run after
the lifecycleBeanProcessor has run: -->
<!--
5.啓用ioc容器中使用shiro的註解，但必須在配置了lifecycleBeanPostProcessor後才能使用
-->
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor"/>
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager"/>
</bean>
<!-- Define the Shiro Filter here (as a FactoryBean) instead of directly in web.xml -
web.xml uses the DelegatingFilterProxy to access this bean. This allows us
to wire things with more control as well utilize nice Spring things such as
PropertiesPlaceholderConfigurer and abstract beans or anything else we might need: -->
<!--
6.配置shiroFilter
6.1 id必須和web.xml中的配合的DelegatingFilterProxy 的filtername一致
如果不一致會拋異常
-->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager"/>
<property name="loginUrl" value="/login.jsp"/>
<property name="successUrl" value="/list.jsp"/>
<property name="unauthorizedUrl" value="/unauthorized.jsp"/>
<!-- The 'filters' property is not necessary since any declared javax.servlet.Filter bean
defined will be automatically acquired and available via its beanName in chain
definitions, but you can perform overrides or parent/child consolidated configuration
here if you like: -->
<!-- <property name="filters">
<util:map>
<entry key="aName" value-ref="someFilterPojo"/>
</util:map>
</property> -->
<!--
配置那些頁面需要受保護，以及訪問這些頁面需要的權限
1）anon 可以別匿名訪問
2)authc 必須認證即登陸後才能訪問的頁面
3)logout登出
url權限採用第一冊匹配優先的方式

/shiro/logout = logout
# everything else requires authentication:

<ehcache>
<!-- Sets the path to the directory where cache .data files are created.
If the path is a Java System Property it is replaced by
its value in the running VM.
The following properties are translated:

if the element is not eternal. Idle time is now - last accessed time
timeToLiveSeconds - Sets the time to live for an element before it expires. Is only used
if the element is not eternal. TTL is now - creation time
overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache
has reached the maxInMemory limit.

<!--Predefined caches. Add your cache configuration settings here.
If you do not have a configuration for your cache a WARNING will be issued when the
CacheManager starts
The following attributes are required for defaultCache:
name - Sets the name of the cache. This is used to identify the cache. It must be unique.
maxInMemory - Sets the maximum number of objects that will be created in memory
eternal - Sets whether elements are eternal. If eternal, timeouts are ignored and the element
is never expired.
timeToIdleSeconds - Sets the time to idle for an element before it expires. Is only used
if the element is not eternal. Idle time is now - last accessed time

if the element is not eternal. TTL is now - creation time
overflowToDisk - Sets whether elements can overflow to disk when the in-memory cache
has reached the maxInMemory limit.

<!-- Sample cache named sampleCache1
This cache contains a maximum in memory of 10000 elements, and will expire
an element if it is idle for more than 5 minutes and lives for more than
10 minutes.
If there are more than 10000 elements it will overflow to the
disk cache, which in this configuration will go to wherever java.io.tmp is
defined on your system. On a standard Linux system this will be /tmp"

6.ShiroRealm.java：注意package的路徑
package com.hc.shiro.ce.realms;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.LockedAccountException;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authc.credential.CredentialsMatcher;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.crypto.hash.SimpleHash;
import org.apache.shiro.realm.AuthenticatingRealm;
import org.apache.shiro.util.ByteSource;
public class ShiroRealm extends AuthenticatingRealm {
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
System.out.println("進入"+token);
//1.把AuthenticationToken轉換爲UsernamePasswordToken
UsernamePasswordToken uptoken = (UsernamePasswordToken) token;
//2.從UsernamePasswordToken獲取username
String username= uptoken.getUsername();
//3.調用數據庫的方法，獲取數據庫中的username對應的用戶記錄
System.out.println("從數據庫查詢數據username:"+username+"對應的信息");
//4.若用戶不存在，則可以拋出異常UnknownAccountException
if("unname".equals(username)){
throw new UnknownAccountException("用戶不存在");
}
//5.根據用戶信息，決定是否需要拋出其他u異常
if("dahuang".equals(username)){
throw new LockedAccountException("用戶被鎖定");
}
//6.根據用戶的情況構建AuthenticationInfo對象並返回，通常使用
//以下信息是從數據庫獲取的
//1.principal:認證的實體信息。可以是username,也可以是數據庫對應的用戶實體對象
Object principal= username;
//2.credentials：密碼
Object credentials="fc1709d0a95a6be30bc5926fdb7f22f4";
//realmName:當前realm對象的name,調用父類的getName()方法即可
String realmName= getName();
SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(principal, credentials, realmName);
return info;
}
public static void main(String[] args) {
String hashAlgorithmName = "MD5";
Object credentials = "123456";
Object salt = ByteSource.Util.bytes("user");
int hashIterations = 1024;
Object result = new SimpleHash(hashAlgorithmName, credentials, null, hashIterations);
System.out.println(result);
}
}
7.寫個登陸的控制器UserAction.java
package com.hc.shiro.ce.action;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
@RequestMapping("/shiro")
public class UserAction {
private Log log = LogFactory.getLog(UserAction.class);
@RequestMapping("/login")
public String login(String name,String password){
Subject currentUser = SecurityUtils.getSubject();
// Do some stuff with a Session (no need for a web or EJB container!!!)
//測試使用session
//獲取session 調用Subject.getSession()
/*Session session = currentUser.getSession();
session.setAttribute("someKey", "aValue");
String value = (String) session.getAttribute("someKey");
if (value.equals("aValue")) {
log.info("--》Retrieved the correct value! [" + value + "]");
}*/
// let's login the current user so we can check against roles and permissions:
//測試當前的用戶是否已經被認證，既是否已經登錄
//調用Subject 的isAuthenticated
if (!currentUser.isAuthenticated()) {
//吧用戶名和密碼封裝成UsernamePasswordToken
UsernamePasswordToken token = new UsernamePasswordToken(name, password);
//RememberMe
token.setRememberMe(true);
try {
//執行登錄
currentUser.login(token);
}
/* //若沒有指定的賬戶，shiro會拋出UnknownAccountException
catch (UnknownAccountException uae) {
log.info("There is no user with username of " + token.getPrincipal());
}
//密碼不對，shiro會拋出IncorrectCredentialsException
catch (IncorrectCredentialsException ice) {
log.info("Password for account " + token.getPrincipal() + " was incorrect!");
}
//用戶被鎖定異常
catch (LockedAccountException lae) {
log.info("The account for username " + token.getPrincipal() + " is locked. " +
"Please contact your administrator to unlock it.");
}*/
// ... catch more exceptions here (maybe custom ones specific to your application?
//所有認證異常的父類
catch (AuthenticationException e) {
System.out.println("登錄失敗: "+e.getMessage());
}
}
return "redirect:/list.jsp";
}
}
