IDEA 生成servlet模板文件案例
servlet模板文件：
1 //package com.servlet; 2 import java.io.File; 3 import java.io.IOException; 4 import java.io.PrintWriter; 5 import java.sql.SQLException; 6 import java.util.ArrayList; 7 import java.util.List; 8 9 import javax.servlet.ServletException; 10 import javax.servlet.annotation.WebServlet; 11 import javax.servlet.http.HttpServlet; 12 import javax.servlet.http.HttpServletRequest; 13 import javax.servlet.http.HttpServletResponse; 14 import javax.servlet.http.HttpSession; 15 16 import com.alibaba.fastjson.JSONObject; 17 18 /** 19 * Servlet implementation class Study_score 20 */ 21 @WebServlet("/Servlet_example") 22 public class Servlet_example extends HttpServlet { 23 protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { 24 // TODO Auto-generated method stub 25 req.setCharacterEncoding("utf-8"); 26 String method = req.getParameter("method"); 27 if ("method_example".equals(method)) { 28 method_example(req, resp); 29 } 30 31 32 33 } 34 public Servlet_example() { 35 super(); 36 // TODO Auto-generated constructor stub 37 } 38 39 private void method_example(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException, SQLException { 40 // TODO Auto-generated method stub 41 //response.getWriter().append("Served at: ").append(request.getContextPath()); 42 req.setCharacterEncoding("utf-8"); 43 resp.setContentType("text/html;charset=utf-8"); 44 HttpSession session=req.getSession(); 45 PrintWriter out=resp.getWriter(); 46 System.out.println("AAAAAAAAAAAAA"); 47 //获取传输过来的值 48 String[] translate_example = req.getParameterValues("translate_example"); 49 50 //返回页面 51 String whole=req.getContextPath()+"/example.html"; 52 String info="上传成功"; 53 resp.getWriter().print("<script> var whole=\""+whole+"\";\r\n" + 54 "var r=confirm(\""+info+"\");\r\n" + 55 "if (r==true){\r\n" + 56 " window.location.assign(whole);\r\n" + 57 " }\r\n" + 58 " else{\r\n" + 59 " window.location.assign(\"./index.jsp\");;\r\n" + 60 " } " 61 + "</script>"); 62 } 63 64 }
