1.创建 Dynamic Web Project ,Dynamic Web module version选择3.0
2.在自动生成 的web.xml配置，增加 metadata-complete="false"
1 <?xml version="1.0" encoding="UTF-8"?> 2 <javaee:web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns="http://Java.sun.com/xml/ns/javaee" 4 xmlns:javaee="http://java.sun.com/xml/ns/javaee" 5 xmlns:web="http://java.sun.com/xml/ns/javaee" 6 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 7 metadata-complete="false" version="3.0"> 8 <javaee:display-name></javaee:display-name> 9 <javaee:welcome-file-list> 10 <javaee:welcome-file>index.html</javaee:welcome-file> 11 </javaee:welcome-file-list> 12 </javaee:web-app>
3.创建监听类，在监听类头部增加 注解 @WebListener
package com.xhkj.listener;
import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; import javax.servlet.annotation.WebListener; @WebListener public class MyServletContextListener implements ServletContextListener { @Override public void contextDestroyed(ServletContextEvent sce) { System.out.println("===========================MyServletContextListener销毁"); } @Override public void contextInitialized(ServletContextEvent sce) { System.out.println("===========================MyServletContextListener初始化"); System.out.println(sce.getServletContext().getServerInfo()); } }
4.启动tomcat服务。打印结果如下
5 注意事项，每次修改配置或者java代码后，要重新编译，否则不起作用
