spring与shiro配置详解

1、加入shiro相关依赖的jar包

pom.xml部分内容如下：

 <dependency>
     <groupId>org.apache.shiro</groupId>
     <artifactId>shiro-spring</artifactId>
     <version>1.3.2</version>
 </dependency>
 <dependency>
     <groupId>org.apache.shiro</groupId>
     <artifactId>shiro-core</artifactId>
     <version>1.3.2</version>
 </dependency>

2、配置web.xml文件

 <!DOCTYPE web-app PUBLIC
  "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
  "http://java.sun.com/dtd/web-app_2_3.dtd" >

 <web-app>
     <display-name>spring.shiro</display-name>
     <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:applicationContext.xml</param-value>
     </context-param>
     <!-- 防止中文乱码过滤器配置 -->
     <filter>
         <filter-name>springFilter</filter-name>
         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
         <init-param>
             <param-name>encoding</param-name>
             <param-value>utf-8</param-value>
         </init-param>
     </filter>
     <!-- 配置shiro filter过滤器，被定义在classpath:applicationContext.xml文件里
         DelegatingFilterProxy实际上是Filter的代理对象，默认情况下，spring会到IOC容器中查找和<filter-name>对应的filter bean，
         也可以通过targetBeanName的初始化参数来配置filter bean的id。
     -->
     <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>springFilter</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>

     <filter-mapping>
         <filter-name>shiroFilter</filter-name>
         <url-pattern>/*</url-pattern>
     </filter-mapping>
     <!-- 配置自动加载 classpath:applicationContext.xml-->
     <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>
     <servlet>
         <servlet-name>springShiro</servlet-name>
         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
         <!-- 配置springmvc -->
         <init-param>
             <param-name>contextConfigLocation</param-name>
             <param-value>classpath:springmvc.xml</param-value>
         </init-param>
         <load-on-startup>1</load-on-startup>
     </servlet>
     <servlet-mapping>
         <servlet-name>springShiro</servlet-name>
         <url-pattern>*.do</url-pattern>
     </servlet-mapping>

     <welcome-file-list>
         <welcome-file>login.jsp</welcome-file>
     </welcome-file-list>
 </web-app>

3、配置applicationContext.xml

1)、配置securityManager，也就是shiro的核心。

2)、配置cacheManager(缓存管理)

3)、配置Realm，自己定义的shiroRealm，必须实现org.apache.shiro.realm.Realm这个接口

4)、配置lifecycleBeanPostProcessor，可以自动的来调用配置在spring IOC 容器中shiro bean的生命周期方法

5)、配置可以使用shiro注解，但必须在配置 lifecycleBeanPostProcessor才可以使用

6)、配置shiroFilter

整个配置文件如下：

 <?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:p="http://www.springframework.org/schema/p"
     xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
     xmlns:tx="http://www.springframework.org/schema/tx" xmlns:util="http://www.springframework.org/schema/util"
     xsi:schemaLocation="
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/util
         http://www.springframework.org/schema/util/spring-util.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx.xsd
         http://www.springframework.org/schema/p
         http://www.springframework.org/schema/p/spring-p.xsd
         ">
     <!--
     1. 配置securityManager，也就是shiro的核心。
      -->
     <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
         <property name="realm" ref="myRealm" />
         <!-- 缓存管理器 -->
         <property name="cacheManager" ref="cacheManager" />
     </bean>
     <!--
     2. 配置cacheManager(缓存管理)
      -->
     <bean id="cacheManager" class="org.apache.shiro.cache.MemoryConstrainedCacheManager">
     </bean>
     <!--
     3. 配置Realm，自己定义的shiroRealm，必须实现org.apache.shiro.realm.Realm这个接口
      -->
     <bean id="myRealm" class="maven.spring.shiro.realms.ShiroRealm"></bean>
     <!--
     4.配置lifecycleBeanPostProcessor， 可以自动的来调用配置在spring IOC 容器中shiro bean的生命周期方法 -->
     <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
     <!--
     5.启用IOC容器中使用shiro的注解，但必须在配置 lifecycleBeanPostProcessor才可以使用-->
     <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>
     <!--
     6. 配置shiroFilter
     6.1 id必须和web.xml 文件中配置的DelegatingFilterProxy的filter-name一致
      -->
     <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
         <property name="securityManager" ref="securityManager" />
         <property name="loginUrl" value="/login.jsp" />
         <property name="successUrl" value="/user/list.do" />
         <property name="unauthorizedUrl" value="/login.jsp" />
         <!-- 配置哪些页面需要受保护
             以及访问这些页面需要的权限
             anon可以被匿名访问，或者说游客可以访问
             authc 必须认证之后才能访问，即登录后才能访问的页面
          -->
         <property name="filterChainDefinitions">
             <value>
                 /login = anon
                 /index = anon
                 /** = authc
             </value>
         </property>

     </bean>

     <context:component-scan base-package="maven.spring.shiro">
         <context:exclude-filter type="annotation"
             expression="org.springframework.stereotype.Controller" />
     </context:component-scan>
 </beans> 

3、配置springmvc文件

 <?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:p="http://www.springframework.org/schema/p"
     xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
     xmlns:mvc="http://www.springframework.org/schema/mvc"
     xsi:schemaLocation="
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
         http://www.springframework.org/schema/tx
         http://www.springframework.org/schema/tx/spring-tx.xsd
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/beans/spring-mvc.xsd
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd">

     <!-- 配置渲染器 -->

     <bean id="jspViewResolver"
         class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <property name="viewClass"
             value="org.springframework.web.servlet.view.JstlView" />
         <property name="prefix" value="/WEB-INF/jsp/" />
         <property name="suffix" value=".jsp" />
     </bean>
     <mvc:default-servlet-handler />
     <mvc:annotation-driven />
     <context:component-scan
         base-package="maven.spring.shiro.web.controller"></context:component-scan>
 </beans>

这样，整个配置文件就配置完成了。
