Shiro学习总结（10）——Spring集成Shiro

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 

<!-- 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 

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

3、添加realm定义 

<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

<span class="code-tag" style="color: rgb(0, 0, 145); background-color: inherit;"><bean id=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"lifecycleBeanPostProcessor"</span> class=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"org.apache.shiro.spring.LifecycleBeanPostProcessor"</span>/></span>

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

<span class="code-tag" style="color: rgb(0, 0, 145); background-color: inherit;"><bean class=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"</span> depends-on=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"lifecycleBeanPostProcessor"</span>/></span>
<span class="code-tag" style="color: rgb(0, 0, 145); background-color: inherit;"><bean class=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"</span>></span>
    <span class="code-tag" style="color: rgb(0, 0, 145); background-color: inherit;"><property name=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"securityManager"</span> ref=<span class="code-quote" style="color: rgb(0, 145, 0); background-color: inherit;">"securityManager"</span>/></span>
<span class="code-tag" style="color: rgb(0, 0, 145); background-color: inherit;"></bean></span>

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"/>
    <!-- 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">

    </select>

</mapper>
