Spring整合Shiro做权限控制模块详细案例分析

1.引入Shiro的Maven依赖

<!-- Spring 整合Shiro需要的依赖 -->

	<dependency>
		<groupId>org.apache.shiro</groupId>
		<artifactId>shiro-core</artifactId>
		<version>1.2.1</version>
	</dependency>
	<dependency>
		<groupId>org.apache.shiro</groupId>
		<artifactId>shiro-web</artifactId>
		<version>1.2.1</version>
	</dependency>
	<dependency>
		<groupId>org.apache.shiro</groupId>
		<artifactId>shiro-ehcache</artifactId>
		<version>1.2.1</version>
	</dependency>
	<dependency>
		<groupId>org.apache.shiro</groupId>
		<artifactId>shiro-spring</artifactId>
		<version>1.2.1</version>
	</dependency>
	<!-- 除此之外还有一些东西也不可少spring, spring-mvc, ibatis等 spring.3.1.2 spring-mvc.3.1.2 
		ibatis.2.3.4 cglib.2.2 -->

2.web.xml中配置

<!-- 配置shiro的核心拦截器 -->
	<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>

3. 编写自己的UserRealm类继承自Realm，主要实现认证和授权的管理操作

package com.jay.demo.shiro;

import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;

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.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;

import com.jay.demo.bean.Permission;
import com.jay.demo.bean.Role;
import com.jay.demo.bean.User;
import com.jay.demo.service.UserService;

public class UserRealm extends AuthorizingRealm{
	
	@Autowired
	private UserService userService;

	/**
	 * 授权操作
	 */
	@Override
	protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
//		String username = (String) getAvailablePrincipal(principals);
		String username = (String) principals.getPrimaryPrincipal();
		
		Set<Role> roleSet =  userService.findUserByUsername(username).getRoleSet();
		//角色名的集合
		Set<String> roles = new HashSet<String>();
		//权限名的集合
		Set<String> permissions = new HashSet<String>();
		
		Iterator<Role> it = roleSet.iterator();
		while(it.hasNext()){
			roles.add(it.next().getName());
			for(Permission per:it.next().getPermissionSet()){
				permissions.add(per.getName());
			}
		}

		
		SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
		
		authorizationInfo.addRoles(roles);
		authorizationInfo.addStringPermissions(permissions);
		
		
		return authorizationInfo;
	}

	/**
	 * 身份验证操作
	 */
	@Override
	protected AuthenticationInfo doGetAuthenticationInfo(
			AuthenticationToken token) throws AuthenticationException {
		
		String username = (String) token.getPrincipal();
		User user = userService.findUserByUsername(username);
		
		if(user==null){
			//木有找到用户
			throw new UnknownAccountException("没有找到该账号");
		}
		/* if(Boolean.TRUE.equals(user.getLocked())) {  
	            throw new LockedAccountException(); //帐号锁定  
	        } */
		
		/**
		 * 交给AuthenticatingRealm使用CredentialsMatcher进行密码匹配，如果觉得人家的不好可以在此判断或自定义实现  
		 */
		SimpleAuthenticationInfo info = new SimpleAuthenticationInfo(user.getUsername(), user.getPassword(),getName());
		
		
		return info;
	}
	
	@Override
	public String getName() {
		return getClass().getName();
	}

}

4.在Spring的applicationContext.xml中进行Shiro的相关配置

1、添加shiroFilter定义

Xml代码

<!– Shiro Filter –>
< bean id = “shiroFilter” class = “org.apache.shiro.spring.web.ShiroFilterFactoryBean” >
< property name = “securityManager” ref = “securityManager” />
< property name = “loginUrl” value = “/login” />
< property name = “successUrl” value = “/user/list” />
< property name = “unauthorizedUrl” value = “/login” />
< property name = “filterChainDefinitions” >
< value >
/ login = anon
/user/** = authc
/role/edit/* = perms[role:edit]
/role/ save = perms [role:edit]
/role/ list = perms [role:view]
/** = authc
</ value >
</ property >
</ bean >

2、添加securityManager定义

Xml代码

< bean id = “securityManager” class = “org.apache.shiro.web.mgt.DefaultWebSecurityManager” >
< property name = “realm” ref = “myRealm” />
</ bean >

3、添加realm定义

Xml代码

< bean id = ” myRealm” class = “com.jay.demo.shiro.

UserRealm<span class="attribute-value" style="font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; background-color: rgb(250, 250, 250);">"</span><span style="color: black; font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; background-color: rgb(250, 250, 250);"> </span><span class="tag" style="font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; color: rgb(0, 102, 153); font-weight: bold; background-color: rgb(250, 250, 250);">/></span><span style="color: black; font-size: 1em; font-family: Monaco, 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', Consolas, 'Courier New', monospace; background-color: rgb(250, 250, 250);">  </span>

4、配置EhCache

< bean id = “cacheManager” class = “org.apache.shiro.cache.ehcache.EhCacheManager” />

5、保证实现了Shiro内部lifecycle函数的bean执行

<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

特别注意：

如果使用Shiro相关的注解，需要在springmvc-servlet.xml中配置一下信息

<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>

备注：Shiro权限管理的过滤器解释：

默认过滤器(10个) 
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 没有参数，表示可以匿名使用。 
authc:例如/admins/user/**=authc表示需要认证(登录)才能使用，没有参数 
roles：例子/admins/user/**=roles[admin],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，当有多个参数时，例如admins/user/**=roles["admin,guest"],每个参数通过才算通过，相当于hasAllRoles()方法。 
perms：例子/admins/user/**=perms[user:add:*],参数可以写多个，多个时必须加上引号，并且参数之间用逗号分割，例如/admins/user/**=perms["user:add:*,user:modify:*"]，当有多个参数时必须每个参数都通过才通过，想当于isPermitedAll()方法。 
rest：例子/admins/user/**=rest[user],根据请求的方法，相当于/admins/user/**=perms[user:method] ,其中method为post，get，delete等。 
port：例子/admins/user/**=port[8081],当请求的url的端口不是8081是跳转到schemal://serverName:8081?queryString,其中schmal是协议http或https等，serverName是你访问的host,8081是url配置里port的端口，queryString是你访问的url里的？后面的参数。 
authcBasic：例如/admins/user/**=authcBasic没有参数表示httpBasic认证 
ssl:例子/admins/user/**=ssl没有参数，表示安全的url请求，协议为https 
user:例如/admins/user/**=user没有参数表示必须存在用户，当登入操作时不做检查
