spring boot监听器的实现

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......");
    }

}
