spring 管理filter

首先在web.xml里面定义filter

targetBeanName是按照bean name引用spring bean多个的话逗号分割

targetFilterLifecycle控制是否执行filter的init以及destory方法

<filter>
  <filter-name>filterProxy</filter-name>
  <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  <init-param>
   <param-name>targetBeanName</param-name>
   <param-value>loginFilter</param-value>
  </init-param>
  <init-param>
   <param-name>targetFilterLifecycle</param-name>
   <param-value>false</param-value>
  </init-param>
 </filter>

 

后面就是配置bean了
