还是大一暑假学的Java，知识掌握了第一阶段的Java基础知识， 后面想自己进阶第二阶段，学习JavaWeb，一直拖到现在直接从Java第二阶段写了~~~
希望指正；
这次主要还是第一个Hello World的开始了~~
我用的IDE是Java EE IDE Mars的
在eclipse中建的文件夹目录如下：
下面是index.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
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>
Hello World
</body>
</html>
MyWeb.java
package com.cn.taobao.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Scanner;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class MyWeb extends HttpServlet {
private String message;
private char termName;
Scanner sc = new Scanner(System.in);
public void init(){
//执行必须的初始化
message = "Hello world。。。。";
System.out.println("Please enter the date ");
int date = sc.nextInt();
System.out.println(date);
}
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException{
//设置响应内容类型
response.setContentType("text/html");
//实际的逻辑是在这里
PrintWriter out = response.getWriter();
out.println("<h1 style=‘color:red‘ onClick=‘alert(‘zbang‘); >" + message + "</h1>");
}
public void destroy(){
//do nothing..
}
}
