我使用的是eclipse+tomcat+mysql的開發環境
1，新建一web項目，過程中切勿忘記點選創建web.xml文件
2，在java Resources中創建servlet
3，在webcontent文件夾中創建一個jsp頁面，下面是我的第一個jsp頁面的信息
<%@ page language="java" contentType="text/html; charset=uf-8"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>this is my first servlet programe</h1>
<hr>
<a href="servlet/HelloServlet">處理get請求</a>
</body>
</html>4，之後開始寫sevlet的程序(重寫doget()方法)
package servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class HelloServlet
*/
@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public HelloServlet() {
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());
System.out.println("處理get請求");
PrintWriter out = response.getWriter();
out.print("<strong>hello servlet</strong><br>");
}
/**
* @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);
}
}
5，在web.xml中配置sevlet信息
增加和信息
之後運行就可以了
