先写好一个servlet模板

package com.exam.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/** * datatime: 2020年7月15日 下午9:04:18 * Servlet implementation class dddd */public class dddd extends HttpServlet {private static final long serialVersionUID = 1L;/** * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) */protected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {// TODO Auto-generated method stubresponse.setContentType("text/html;charset=utf-8");request.setCharacterEncoding("utf-8");}/** * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) */protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {// TODO Auto-generated method stubdoGet(request, response);}}

2.添加到eclipse模板中

再点击ok

应用并关闭

再打开的类中输入servlet按alt+/

就会输出当前的模板
