拦截器的写法

package com.buaa.nstrimon.intercepter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.WebContentInterceptor;

import com.buaa.nstri.dao.demo.UserTestDao;
import com.buaa.nstri.service.demo.impl.TestUtilServiceImpl;


/**
 * 这个拦截器为默认拦截器，用来对请求scope塞默认的数据

 */
public class TestInterceptor extends WebContentInterceptor{

	

	
	@Override
	public void postHandle(HttpServletRequest request,
			HttpServletResponse response, Object handler,
			ModelAndView modelAndView) throws Exception {
		//这里可以设置一些默认的参数值
		System.out.println("out");
	}

	@Override
	public boolean preHandle(HttpServletRequest request,
			HttpServletResponse response, Object handler)
			throws ServletException {
		//这里可以设置一些默认的参数值
		System.out.println("in");

		return super.preHandle(request, response, handler);
	}
