有人用过OncePerRequestFilter么？？？

[不关橙猫猫事的哦]

听说OncePerRequestFilter只执行一次，但是我用来过滤jsp，每次访问jsp都执行啊，不是说只执行一次吗？？？


导入spring-web.jar spring-beans.jar spring-core.jar

<filter>
		<filter-name>OncePerRequestFilter</filter-name>
		<filter-class>filter.TestFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>OncePerRequestFilter</filter-name>
		<url-pattern>*.jsp</url-pattern>
	</filter-mapping>

package filter;

import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.filter.OncePerRequestFilter;

public class TestFilter extends OncePerRequestFilter
{
	public void doFilterInternal(HttpServletRequest request,HttpServletResponse response,FilterChain chain)
		throws ServletException,IOException
	{
		System.out.println("begin");
		chain.doFilter(request, response);
		System.out.println("end");
	}
}
