1.JSP开发模型

为了方便使用JSP技术,SUN公司玮JSP技术提供了两种开发模型:JSP Mode1 和 JSP Mode2.

JSP Mode1:

 JSP Mode2:

 我们将按照Model2思想来完成用户注册功能;

1.创建项目,编写JavaBean

(1)编写一个UserBean类,用于封装用户信息,代码如下:

package chapter14.jsp;

public class UserBean {
	private String name;
	private String password;
	private String email;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	
}

(2) 编写RegisterFormBean类,用于封装注册表单

package chapter14.jsp;

import java.util.HashMap;
import java.util.Map;

public class RegisterFormBean {

	//1.用来封装注册参数的
	private String name;
	private String password;
	private String password2;
	private String email;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getPassword2() {
		return password2;
	}
	public void setPassword2(String password2) {
		this.password2 = password2;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	//------------进行服务端的数据-----------------------
	//2.定义变量来接收用户校验的信息，比如说用户名、邮箱是否符合规范,
	//第一个参数 属性名称  第二个参数：属性值是否符合规范信息,比如（“email”,”邮箱格式有误“）；
	private Map<String,String> errors = new HashMap<String,String>();
	public boolean validate(){
		//2.定义变量，来判断数据是否满足规范，如果满足 就返回true,不满足就返回false
		boolean flag = true;
		if(name == null || name.trim().equals("")){
			errors.put("name","请输入用户名");
			flag = false;
			return flag;
