一、开发工具及实现方法
选择Myeclipse2017进行开发，配置：jdk1.8、tomcat8.5。
实现方法：前端：html+css+js；后台：java。
基于JavaWeb开发，采用B/S结构。
二、项目进展
2.1前端
1、建立了响应式登录界面，适配chrome浏览器及手机界面。
2、游戏界面适配框架，使系统风格保持一致。
2.2后端
1、连接数据库，实现邮箱注册、找回密码功能，对无效输入进行检错并提示。
2.3游戏内容
1、添加选项：修改游戏规则，每人每轮可以输入两个数字。
2.4后续添加
1、添加管理员用户的用户管理模块
2、实现联机功能
3、实现更多可视化图表
三、前端登录页面

// 1、创建参数配置，用于连接邮箱服务器的参数配置
Properties props = new Properties();
// 开启debug调试
props.setProperty("mail.debug", "true");
// 发送服务器需要身份验证
props.setProperty("mail.smtp.auth", "true");
// 设置右键服务器的主机名

props.put("mail.smtp.socketFactory.port", "465");
// 发送邮件协议名称
props.setProperty("mail.transport.protocol", "smtp");
// 2、根据配置创建会话对象，用于和邮件服务器交互
Session session = Session.getInstance(props);
// 设置debug，可以查看详细的发送log
session.setDebug(true);
// 3、创建一封邮件
String code = RandomUtil.getRandom();
System.out.println("邮箱验证码：" + code);
String html = htmlText.html(code);
MimeMessage message = JavaMailUtil.creatMimeMessage(session, JavaMailUtil.emailAccount,
JavaMailUtil.receiveMailAccount, html);
// 4、根据session获取邮件传输对象
Transport transport = session.getTransport();
// 5、使用邮箱账号和密码连接邮箱服务器emailAccount必须与message中的发件人邮箱一致，否则报错
transport.connect(JavaMailUtil.emailAccount, JavaMailUtil.emailPassword);
// 6、发送邮件,发送所有收件人地址
transport.sendMessage(message, message.getAllRecipients());
System.out.println("邮件已发送" );
// 7、关闭连接
transport.close();
System.out.println("链接关闭" );
// 写入session
HttpSession hs = req.getSession(true);
hs.setAttribute("code", code);
JSONObject jsonObj=new JSONObject();
jsonObj.put("code", code);
jsonObj.put("result_msg","ok"); //如果发生错误就设置成"error"等
jsonObj.put("result_code",0); //返回0表示正常，不等于0就表示有错误产生，错误代码
System.out.println("最后构造得到的json是："+jsonObj.toString());
resp.setContentType("text/html; charset=UTF-8");
try {
resp.getWriter().print(jsonObj);
resp.getWriter().flush();
resp.getWriter().close();
} catch (IOException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
req.getSession().setAttribute("error", "邮件发送失败");
}
