1 效果展示
（1）登录界面
（2）注册界面
（3）动图展示
2 内容说明
（1）开发前，需引入一个连接Mysql 数据库驱动mysql-connector-java-5.1.30-bin.jar包
提取码：6666
（2）构建路径
(3)需要下载xampp软件
xampp软件下载
提取码：2255
xampp软件包含
Apache
Web服务器、
Mysql
Web服务器、Filezilla Web服务器、Mercury服务器以及Tomcat Web服务器。在本项目中，我们只需要开启Apache服务器和Mysql服务器即可。
3 主要代码

mysqlDataSource.setUser("root");//mysql数据库的用户名
mysqlDataSource.setPassword("123456");//密码
connection = mysqlDataSource.getConnection();}catch(Exception e){
JOptionPane.showMessageDialog(null,"数据库连接失败","提示", JOptionPane.WARNING_MESSAGE);}}}
（4）登录所需要的数据转入
package com.weh.User;//登录所需要的数据转入publicclassLogin{
String name;
String password;
LoginDemo loginDemo;
String mail;
String tField;boolean tem;publicbooleanisTem(){return tem;}publicvoidsetTem(boolean tem){this.tem = tem;}public String gettField(){return tField;}publicvoidsettField(String tField){this.tField = tField;}boolean loginSuccess =false;public String getQQmail(){return mail;}publicvoidsetQQmail(String mail){this.mail = mail;}public LoginDemo getLoginDemo(){return loginDemo;}publicvoidsetLoginDemo(LoginDemo loginDemo){this.loginDemo = loginDemo;}public String getName(){return name;}publicvoidsetName(String id){this.name = id;}public String getPassword(){return password;}publicvoidsetPassword(String password){this.password = password;}publicbooleanisLoginSuccess(){return loginSuccess;}publicvoidsetLoginSuccess(boolean loginSuccess){this.loginSuccess = loginSuccess;}}
（5）注册所需要的数据转入
package com.weh.User;//注册所需要的数据转入publicclassRegister{

connection.close();
prepare.close();
resultSet.close();
loginSuccess = login.isLoginSuccess();}catch(SQLException| InterruptedException e){
JOptionPane.showMessageDialog(null,"异常","警告", JOptionPane.ERROR_MESSAGE);}}}
（7）注册验证的代码如下：
package com.weh.User;import com.weh.Mail.SendMail;import javax.swing.*;import java.sql.Connection;import java.sql.PreparedStatement;import java.sql.SQLException;//插入数据，以及对数据库驱动的开启publicclassUserRegister{//注册数据处理者

String sql1 ="INSERT INTO test.User VALUES (?,?,?)";//插入语句try{
presql1 = connection.prepareStatement(sql1);//发送插入语句
presql1.setString(1,register.getMail());
presql1.setString(2,register.getPassword());
presql1.setString(3,register.getName());
flag = presql1.executeUpdate();//成功插入式返回1newThread(newSendMail(register.getMail(),"HI注册验证/您好:"+"\n\t您成功绑定了您的邮箱，您可登录HI。")).start();if(flag!=0){
JOptionPane.showMessageDialog(null,"注册成功");}else{
JOptionPane.showMessageDialog(null,"注册失败","提示",JOptionPane.WARNING_MESSAGE);}//释放资源和空间
connection.close();
presql1.close();}catch(SQLException e){
JOptionPane.showMessageDialog(null,"注册失败！","警告",JOptionPane.WARNING_MESSAGE);}}}
