spring boot监听器的实现

如下所示：

import javax.servlet.ServletContextEvent;

import javax.servlet.ServletContextListener;

import javax.servlet.annotation.WebListener;

@WebListener

public class ContextListener implements ServletContextListener {

    public ContextListener() {

        // TODO Auto-generated constructor stub

    }

    public void contextDestroyed(ServletContextEvent arg0)  {

        System.out.println("监听器被销毁......");

    }

    public void contextInitialized(ServletContextEvent arg0)  {

        System.out.println("监听器初始化......");

    }

}
