ssm整合shiro

风流意气都作罢 提交于 2020-01-27 01:15:44

1.shiro基础

  • 简介

    ​ Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码学和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。

  • 主要功能

    • 三个核心组件:Subject, SecurityManager 和 Realms.
    • Subject:即“当前操作用户”。但是,在Shiro中,Subject这一概念并不仅仅指人,也可以是第三方进程、后台帐户(Daemon Account)或其他类似事物。它仅仅意味着“当前跟软件交互的东西”。但考虑到大多数目的和用途,你可以把它认为是Shiro的“用户”概念。
    • Subject代表了当前用户的安全操作,SecurityManager则管理所有用户的安全操作。
    • SecurityManager:它是Shiro框架的核心,典型的Facade模式,Shiro通过SecurityManager来管理内部组件实例,并通过它来提供安全管理的各种服务。
    • Realm: Realm充当了Shiro与应用安全数据间的“桥梁”或者“连接器”。也就是说,当对用户执行认证(登录)和授权(访问控制)验证时,Shiro会从应用配置的Realm中查找用户及其权限信息。 从这个意义上讲,Realm实质上是一个安全相关的DAO:它封装了数据源的连接细节,并在需要时将相关数据提供给Shiro。当配置Shiro时,你必须至少指定一个Realm,用于认证和(或)授权。配置多个Realm是可以的,但是至少需要一个。
    • Shiro内置了可以连接大量安全数据源(又名目录)的Realm,如LDAP、关系数据库(JDBC)、类似INI的文本配置资源以及属性文件等。如果缺省的Realm不能满足需求,你还可以插入代表自定义数据源的自己的Realm实现。

2.与SSM整合

  • 首先创建好ssm的maven项目,创好目录

  • 配置文件(除了ssm原本的配置还需要配置的配置文件)

    • 添加pom依赖
      <properties>
        <shiro.version>1.3.2</shiro.version>
      </properties>

    <!-- end shiro -->
    
    • web.xml添加配置
    <!-- Shiro Filter is defined in the spring application context: -->
    <filter>

        <bean id="filterChainDefinitionMap" factory-bean="filterChainDefinitionsBuilder" factory-method="builder"/>

    • 添加ehcache.xml配置文件
    <?xml version="1.0" encoding="UTF-8"?>
    <ehcache updateCheck="false" dynamicConfig="false">
        <diskStore path="java.io.tmpdir"/>
    
        <defaultCache
                maxElementsInMemory="1000"
                eternal="false"
                overflowToDisk="true"
                timeToIdleSeconds="120"
                timeToLiveSeconds="120"
                diskPersistent="false"
                diskExpiryThreadIntervalSeconds="120"
                memoryStoreEvictionPolicy="LRU"
        />
    
        <cache name="cache_test"

               memoryStoreEvictionPolicy="FIFO"
        />
    </ehcache>
    
  • 编写Controller代码,进行身份验证

    @RequestMapping(value="login",method = RequestMethod.GET)
    public Object login(@RequestParam String username, String password) {
        Map<String, Object> map = new HashMap<>();
        map.put("code",0);
        /*shiro进行权限管理操作*/
        //获取正在请求认证的用户
        Subject currentUser = SecurityUtils.getSubject();
        //为了方便测试,加的第二次登陆之前先清除第一次登陆的状态,后期要删除
        if (currentUser.isAuthenticated()) {
            System.out.println("正在清除上一个用户的登陆状态!!");
            currentUser.logout();
        }
        if (!currentUser.isAuthenticated()) {
            System.out.println(username+" : "+password);
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);
            token.setRememberMe(true);
            try {
                currentUser.login(token);
            } catch (UnknownAccountException uae) {//用户名不存在
                map.put("code",1);
                map.put("msg",uae.getMessage());
            } catch (IncorrectCredentialsException ice) {//凭证匹配异常
                map.put("code",1);
                map.put("msg","密码输入有误!");
            } catch (LockedAccountException lae) {//锁定用户异常
                map.put("code",1);
                map.put("msg",lae.getMessage());
            } catch (AuthenticationException ae) {//认证异常
                map.put("code",1);
                map.put("msg",ae.getMessage());
            }
        }
        return map;
    }
    
  • 编写xxRealm.class,进行认真和授权(下面仅含有认真,授权往后)

  • 注册时需要的加密代码

    public static void main(String[] args) {
        //加密的名称,可以查看shiro底层提供的名称
        String hashAlgorithmName = "MD5";
        //加密时使用的盐值

        //要加密的密码
        String credentials = "123456";
        //调用shiro底层的加密算法
        Object newCredentials = new SimpleHash(hashAlgorithmName, credentials, salt, 3);//3是加密次数,要保证和配置文件一致
        System.out.println(newCredentials);
    }
    
  • 使用数据库存储页面权限需要的配置类

  • 数据库表(存储资源路径及对应的访问权限)

    在这里插入图片描述

1.详细学习
  • 拦截器

            logout:退出拦截器(认证成功后进行清除认证操作)
            roles: [角色名称,角色名称...] (,表示需要多个权限,and关系)权限过滤器(只有具备指定权限的人才能访问对应权限的页面)
        -->

  • 开启shiro注解配置mvc配置文件添加(未测试)

     <!-- 开启shiro的注解支持 -->
    	<bean id="defaultAdvisorAutoProxyCreator" class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator">
    		<!-- 必须改为true,即使用cglib方式为Action创建代理对象。默认值为false,使用JDK创建代理对象,会造成问题 -->
    		<property name="proxyTargetClass" value="true"></property>
    	</bean>
    	
    	<!-- 使用shiro框架提供的切面类,用于创建代理对象 -->
    	<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor"></bean>
