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

[html] view
plain copy

<!-- 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

[html] view
plain copy

<!-- 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

[java] view
plain copy

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/>

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：

[java] view
plain copy

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：

[java] view
plain copy

<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：

[java] view
plain copy

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

[java] view
plain copy

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

[java] view
plain copy

<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

[java] view
plain copy

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

[html] view
plain copy

<?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"/>

<!-- 再在role中关联role和permission -->

<collection property="permissionSet" column="permissionid" ofType="com.jay.demo.bean.Permission">

<id property="id" column="permission_id"/>

<result property="name" column="permission_name"/>

</collection>

</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">

<result property="id" column="ROLE_ID" />

<result property="name" column="ROLE_NAME" />

</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>
