Struts2 过滤器

情况1、不使用自定义过滤器
<!-- 5.filter -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>

<!-- 6.filter-mapping -->
<!-- 配置Filter拦截的URL -->
<filter-mapping>
<!-- 配置Struts2的核心FilterDispatcher拦截所有用户请求 -->
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

情况2、使用自定义过滤器
<!-- 拆分StrutsPrepareAndExecuteFilter后，可以在中间加入自定义过滤器，然后在filter-mapping加入过滤器映射-->
<filter>
<filter-name>StrutsPrepareFilter</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter
</filter-class>
</filter>
<!-- 自定义的过滤器
<filter>
<filter-name>SelfCustomFilter</filter-name>
<filter-class>com.filter.PageFilter
</filter-class>
</filter> -->
<filter>
<filter-name>StrutsExecuteFilter</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter
</filter-class>
</filter>

<!-- 6.filter-mapping -->
<!-- 配置Filter拦截的URL -->
<filter-mapping>
<filter-name>StrutsPrepareFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<filter-mapping>
<filter-name>StrutsExecuteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
