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  收藏代码
  1. <!-- Shiro Filter -->  
  2. <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">  
  3.     <property name="securityManager" ref="securityManager" />  
  4.     <property name="loginUrl" value="/login" />  
  5.     <property name="successUrl" value="/user/list" />  
  6.     <property name="unauthorizedUrl" value="/login" />  
  7.     <property name="filterChainDefinitions">  
  8.         <value>  
  9.             /login = anon  
  10.             /user/** = authc  
  11.             /role/edit/* = perms[role:edit]  
  12.             /role/save = perms[role:edit]  
  13.             /role/list = perms[role:view]  
  14.             /** = authc  
  15.         </value>  
  16.     </property>  
  17. </bean>  

2、添加securityManager定义 
Xml代码  收藏代码
  1. <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">  
  2.     <property name="realm" ref="myRealm" />  
  3. </bean>  

3、添加realm定义 
Xml代码  收藏代码
  1. <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 


关于Shiro的标签应用:

<shiro:authenticated> 登录之后
<shiro:notAuthenticated> 不在登录状态时
<shiro:guest> 用户在没有RememberMe时
<shiro:user> 用户在RememberMe时
<shiro:hasAnyRoles name="abc,123" > 在有abc或者123角色时
<shiro:hasRole name="abc"> 拥有角色abc
<shiro:lacksRole name="abc"> 没有角色abc
<shiro:hasPermission name="abc"> 拥有权限abc
<shiro:lacksPermission name="abc"> 没有权限abc
<shiro:principal> 显示用户登录名


以上是Shiro的相关配置,出于安全的考虑,一般都会使用ACL(基于角色的用户权限管理去控制用户登录后的权限)

ACL详细代码案例如下:


涉及到的表:3+2(User,Role,Permission  +  user-role,role-permission)

3张实体表+2张关系表

1.关于User类:

package com.jay.demo.bean;

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

public class User {
	private String id;
	private String username;
	private String password;
	private Set<Role> roleSet = new HashSet<Role>();
	
	public User() {
	}

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public Set<Role> getRoleSet() {
		return roleSet;
	}

	public void setRoleSet(Set<Role> roleSet) {
		this.roleSet = roleSet;
	}

	
}


2.关于Role表

package com.jay.demo.bean;

import java.io.Serializable;
import java.util.HashSet;
import java.util.Set;

public class Role implements Serializable {

	private static final long serialVersionUID = -4987248128309954399L;

	private Integer id;
	private String name;
	private Set<Permission> permissionSet = new HashSet<Permission>();

	public Role() {
		super();
	}
	
	// --------------------------------------------------------------------------------

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((id == null) ? 0 : id.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		Role other = (Role) obj;
		if (id == null) {
			if (other.id != null)
				return false;
		} else if (!id.equals(other.id))
			return false;
		return true;
	}
	
	// --------------------------------------------------------------------------------

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public Set<Permission> getPermissionSet() {
		return permissionSet;
	}

	public void setPermissionSet(Set<Permission> permissionSet) {
		this.permissionSet = permissionSet;
	}

}


3.关于permission表

<pre name="code" class="java">package com.jay.demo.bean;

import java.io.Serializable;

public class Permission implements Serializable {

	private static final long serialVersionUID = -8025597823572680802L;

	private Integer id;
	private String name;

	public Permission() {
		super();
	}

	// --------------------------------------------------------------------------------------

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((id == null) ? 0 : id.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		Permission other = (Permission) obj;
		if (id == null) {
			if (other.id != null)
				return false;
		} else if (!id.equals(other.id))
			return false;
		return true;
	}

	// --------------------------------------------------------------------------------------

	public Integer getId() {
		return id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}



4.dao层接口

package com.jay.demo.dao;

import com.jay.demo.bean.User;

public interface UserDao {
	
	User findUserByUsername(String username); 
}


4.使用Mybatis完成的Dao层实现


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.jay.demo.dao.UserDao">
	<resultMap id="userMap" type="com.jay.demo.bean.User">
	<id property="id" column="USER_ID"/>
	<result property="username" column="USER_USERNAME"/>
	<result property="password" column="USER_PASSWORD"/>
	<!-- 进行 多表关联插叙,先关联user和role -->
	<collection property="roleSet" column="roleid" ofType="com.jay.demo.bean.Role">
	<id property="id" column="ROLE_ID"/>
	<result property="name" column="ROLE_NAME"/>

	</collection>
	
	</resultMap>
	
	
	
	
	<!--  通过User来查找Role   -->  
    <!-- <select id="selectRoleByUser" parameterType="int" resultMap="RoleMap">  
        select * from tbl_role_user user_id  = #{id}   
    </select>  
    

	<resultMap  id="roleMap" type="com.jay.demo.bean.User">

	</resultMap>
	
	<resultMap id="permissionMap" type="com.jay.demo.bean.Permission">
		<result property="id" column="PERMISSION_ID" />
		<result property="name" column="PERMISSION_NAME" />
	</resultMap> -->
	
	

<sql id="select-base-01">  
        SELECT   
            u.USER_ID,  
            u.USER_USERNAME,  
            u.USER_PASSWORD,  
            r.ROLE_ID,  
            r.ROLE_NAME,  
            p.PERMISSION_ID,  
            p.PERMISSION_NAME  
        FROM  
          tbl_user as u,  
          tbl_role as r,  
          tbl_permission as p,  
          tbl_permission_role as pr,  
          tbl_role_user as ru  
        WHERE  
          u.USER_ID = ru.USER_ID  
        AND  
          r.ROLE_ID = ru.ROLE_ID  
        AND  
          p.PERMISSION_ID = pr.PERMISSION_ID  
        AND  
          r.ROLE_ID = pr.ROLE_ID  
    </sql>  
    
    <select id="findUserByUsername" parameterType="string" resultMap="userMap">  
       <include refid="select-base-01" />  
        AND  
            u.USER_USERNAME = #{username}    
            <!-- select * from tbl_user u, tbl_role r, tbl_role_user tu 
            where u.user_id = tu.user_id and r.role_id = tu.role_id 
            and user_username=#{username} -->
    </select>
    
</mapper>
