Eclipse IDE 下载 Web 插件方法

代码应该按功能按职责进行不同层面的划分（放不同的包里）

用户层：交互页面
业务层：提供该软件系统的业务功能
持久层：提供基础数据的增删改查的操作
（最底层是数据库）

浏览器访问页面
http://localhost:8080/SchoolManager/login.jsp
不能用https

定义Admin 和 Student 类

package com.iflytek.stumanager.po;

public class Admin {
	
	private int id;
	private String account;
	private String password;
	
	public Admin(int id, String account, String password) {
		super();
		this.id = id;
		this.account = account;
		this.password = password;
	}

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getAccount() {
		return account;
	}

	public void setAccount(String account) {
		this.account = account;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
	
}

package com.iflytek.stumanager.po;

public class Student {
	
	private int id;
	private String name;
	private int age;
	private String address;
	
	public Student(int id, String name, int age, String address) {
		super();
		this.id = id;
		this.name = name;
		this.age = age;
		this.address = address;
	}

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public String getAddress() {
		return address;
	}

	public void setAddress(String address) {
		this.address = address;
	}
	
}

建立JSPFile

先引入 Web jar包去掉报错
修改JSP的默认编码方式为UTF-8（可用汉字）

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
	<h2>用户登录</h2>
	<hr />
	<form action="" method="post">
		账号：<input type="text" name="account" /><br />
		密码：<input type="password" name="password" /><br />
		<input type="submit" value="提交" />
	</form>
</body>
</html>
