ssm项目集成shiro

首先，这是创建ssm项目的地址：http://blog.csdn.net/qq_40706089/article/details/78707234，今天打算将shiro安全框架也给集成进来，网上对shiro的介绍非常之多，在这也不多赘述了，直接开始集成。

step1：通过pom文件管理shiro框架所需的jar包

<!--整合shiro需要的依赖-->

<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-core</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-web</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.2.2</version>
</dependency>
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-ehcache</artifactId>
<version>1.2.2</version>
</dependency>

step2：在web.xml中添加shiro安全过滤器

<filter>
<filter-name>shiroFilter</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
<init-param>
<param-name>targetFilterLifecycle</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>shiroFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

这个要注意两个小问题：a.一般shiro过滤器配置在编码过滤器之后，这样在对编码进行过滤后就走shiro的过滤器。b.

<filter-name>shiroFilter</filter-name>

此处的名字要和下一步的spring-shiro.XML中

ShiroFilterFactoryBean 的id一样，如果不一样 会创建shiroFilter失败

step3：在resourse目录下建立spring-shiro.XML文件（此处名字 随意）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd" default-lazy-init="true">

<description>Shiro Configuration</description>

<!-- Shiro's main business-tier object for web-enabled applications -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="realm" ref="MyRealm" />
<property name="cacheManager" ref="cacheManager" />
</bean>

<!-- 項目自定义的Realm -->
<bean id="MyRealm" class="com.lsd.shiro.MyRealm">
<property name="cacheManager" ref="cacheManager" />
</bean>
<!--自定义LogoutFilter,退出-->
<bean id="logoutFilter" class="com.lsd.shiro.SystemLogoutFilter">
<property name="redirectUrl" value="/userController/login"/>
</bean>

<!-- Shiro Filter -->
<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager" />
<property name="loginUrl" value=" /userController/login" />
<property name="successUrl" value="userController/index" />
<property name="filters">
<map>

<entry key="logout" value-ref="logoutFilter"/>
</map>
</property>

<property name="filterChainDefinitions">
<value>
/userController/login = anon

/userController/index =authc
/userController/logout = logout

</value>
</property>
</bean>

<!-- 用户授权信息Cache -->
<bean id="cacheManager" class="org.apache.shiro.cache.MemoryConstrainedCacheManager" />

<!-- 保证实现了Shiro内部lifecycle函数的bean执行 -->
<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />

<!-- AOP式方法级权限检查 -->
<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
depends-on="lifecycleBeanPostProcessor">
<property name="proxyTargetClass" value="true" />
</bean>

<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
<property name="securityManager" ref="securityManager" />
</bean>

</beans>

配置解释：

<bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
<property name="securityManager" ref="securityManager" />
<property name="loginUrl" value=" /userController/login" />
<property name="successUrl" value="userController/index" />
<property name="filters">
<map>

<entry key="logout" value-ref="logoutFilter"/>
</map>
</property>

<property name="filterChainDefinitions">
<value>
/userController/login = anon

/userController/index =authc
/userController/logout = logout

</value>
</property>
</bean>

securityManager：是shiro 的安全管理器

loginUrl：登录页面，也可以当成是项目的首页

successUrl：登录成功后的页面

后面跟的都是访问页面的路由，然后在value里面进行配置

路径1 = anon 代表不需要经过登录验证即可访问，即无拦截。

路径2 = authc 代表必须通过登录验证才可访问，如果不登录直接访问 则返回loginUrl

注意：配置成功后先注释掉自定义的realm，下篇博客会用到

step4：

在web.xml文件中引入shiro的配置文件让他随项目启动时就加载

<display-name>web-ssm</display-name>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mybatis.xml,classpath:spring-shiro.xml</param-value>
</context-param>

<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log4j.properties</param-value>
</context-param>

至此，shiro框架就集成进来了 ，测试是否集成成功，可以将某个页面的地址加上 authc 权限 不登录访问的时候如果能拦截，跳到loginUrl，代表集成成功，具体用法还需要深入的学习，在这推荐开涛大神的跟我学shiro。
