Struts2 过滤器

Posted 2020-06-17

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>
