shiro实战整合

　　引入依赖（包括缓存等）：

        <!-- SECURITY begin -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>${shiro.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>${shiro.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-cas</artifactId>
            <version>${shiro.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>commons-logging</groupId>
                    <artifactId>commons-logging</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>${shiro.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-ehcache</artifactId>
            <version>${shiro.version}</version>
        </dependency>
        <!-- SECURITY end -->

 

　　由于shiro是通过过滤器拦截的，所以第一步在web.xml中进行过滤器的配置

　　web.xml:

<!-- shiro的filter -->
    <!-- shiro过虑器，DelegatingFilterProxy通过代理模式将spring容器中的bean和filter关联起来 -->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <!-- 设置true由servlet容器控制filter的生命周期 -->
        <init-param>
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
        <!-- 【可选】设置spring容器filter的bean id，如果不设置则找与filter-name一致的bean-->
        <init-param>
            <param-name>targetBeanName</param-name>
            <param-value>shiroFilter</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

　　全部web.xml中应包含 spring监听 springMVC监听 shiro过滤器 POST乱码处理等，示例：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>permission_shiro1110</display-name>
  
  <!-- 配置spring容器监听器 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/classes/spring/applicationContext-*.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>



    <!-- 前端控制器 -->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 加载springmvc配置 -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <!-- 配置文件的地址 如果不配置contextConfigLocation， 默认查找的配置文件名称classpath下的：servlet名称+"-serlvet.xml"即：springmvc-serlvet.xml -->
            <param-value>classpath:spring/springmvc.xml</param-value>
        </init-param>

    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <!-- 可以配置/ ，此工程 所有请求全部由springmvc解析，此种方式可以实现 RESTful方式，需要特殊处理对静态文件的解析不能由springmvc解析 
            可以配置*.do或*.action，所有请求的url扩展名为.do或.action由springmvc解析，此种方法常用 不可以/*，如果配置/*，返回jsp也由springmvc解析，这是不对的。 -->
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
    
    <!-- shiro的filter -->
    <!-- shiro过虑器，DelegatingFilterProxy通过代理模式将spring容器中的bean和filter关联起来 -->
    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <!-- 设置true由servlet容器控制filter的生命周期 -->
        <init-param>
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
        <!-- 设置spring容器filter的bean id，如果不设置则找与filter-name一致的bean-->
        <init-param>
            <param-name>targetBeanName</param-name>
            <param-value>shiroFilter</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>shiroFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    
    
    <!-- post乱码处理 -->
