SpringBoot复习：（57）ServletRequestListener

package cn.edu.tju.confiig;


import org.springframework.context.annotation.Configuration;

import javax.servlet.ServletRequestEvent;
import javax.servlet.ServletRequestListener;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;

@Configuration
public class MyServletRequestListener implements ServletRequestListener {
    @Override
    public void requestInitialized(ServletRequestEvent sre) {
        HttpServletRequest httpServletRequest=(HttpServletRequest)sre.getServletRequest();
        System.out.println(httpServletRequest.getServletPath() + "初始化");
    }

    @Override
    public void requestDestroyed(ServletRequestEvent sre) {
        HttpServletRequest httpServletRequest=(HttpServletRequest)sre.getServletRequest();
        System.out.println(httpServletRequest.getServletPath() + "销毁");

    }


}

基于配置文件的spring mvc 的话，需要配置@ComponentScan并配置web.xml,示例

<listener>
    <listener-class>
      cn.edu.tju.config.MyServletRequestListener
    </listener-class>
  </listener>
