html+JavaBean+jsp实现用户注册

1.建立JavaBean，包含username和passsword属性以及regist()方法
2.建立regist.html页面，包含一个表单，提交到regist.jsp页面进行处理
3.建立regist.jsp页面，set属性值，调用JavaBean中的regist方法()进行注册

UserInfo.java：

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;

import myPackage.MySqlClass;

public class UserInfo {

    private String username ;
    private String password ;
    public String getUsername() {
        return username;
    }
    public void setUsername(String name) {
        this.username = name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public void regist(){
        Connection con=null;
        try {
            con= MySqlClass.MyConnection("db_students");
        } catch (ClassNotFoundException e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        } catch (SQLException e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        }
        //注册
        String regString="insert into tb_users (用户名,密码) values (?,?)";
        try {
            PreparedStatement ps=con.prepareStatement(regString);
            ps.setString(1, this.username);
            ps.setString(2, this.password);
            ps.executeUpdate();
        } catch (SQLException e) {
            // TODO 自动生成的 catch 块
            e.printStackTrace();
        }
    }


}

regist.html:

<!DOCTYPE html>

<meta charset="UTF-8">

<form action="regist.jsp" method="post">
