实验一区分Servlet中Get和Post请求处理方法

新建工程
新建Servlet类
Eclipse已经帮助我们在web.xml中配置好
新建html文件，命名为login.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="Test" method="get">
    <input type="text" name="test1"/>
    <input type="submit" value="submit"/>
</form>
<hr/>
<form action="Test" method="post">
    <input type="text" name="test2"/>
    <input type="submit" value="submit"/>
</form>
</body>
</html>

Test.java的代码为：


package com;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**

Servlet implementation class Test
*/
public class Test extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
- @see HttpServlet#HttpServlet()
  */
  public Test() {
  super();
  // TODO Auto-generated constructor stub
  }
  /**
- @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
  */
  protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  // TODO Auto-generated method stub
  // response.getWriter().append("Served at: ").append(request.getContextPath());
  PrintWriter writer = response.getWriter();
  writer.println("this is the Get method.test1="+request.getParameter("test1"));
  }
/**
- @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
  */
  protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  // TODO Auto-generated method stub
  // doGet(request, response);
  PrintWriter writer = response.getWriter();
  writer.println("this is the Post method.test2="+request.getParameter("test2"));
  }
  }
结果：

由实验可知get和post方法的不同。
