只记录有关shiro的部分，详见:http://how2j.cn/k/shiro/shiro-ssm/1727.html#nowhere

一 web.xml

1. 指定配置shiro的文件
2. 配置过滤器

<!-- spring的配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:applicationContext.xml,
            classpath:applicationContext-shiro.xml
        </param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

 <!-- Shiro配置 -->
    <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>

二 applicationContext-shiro.xml``

提供shiro的相关配置，简单的说，就是把shiro.ini里的内容搬到这个xml文件里面来了，只是写法不同

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

三 springMVC.xml

1. springmvc的基本配置
2. 增加了对shiro的支持。
   这样可以在控制器Controller上，使用像@RequireRole 这样的注解，来表示某个方法必须有相关的角色才能访问
3. 指定了异常处理类DefaultExceptionHandler，这样当访问没有权限的资源的时候，就会跳到统一的页面去显示错误信息

    <!--启用shiro注解 -->
    <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>
     
    <!-- 控制器异常处理 -->
    <bean id="exceptionHandlerExceptionResolver" class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver">
    </bean>
    <bean class="com.how2java.exception.DefaultExceptionHandler"/>
