【说明】今天上午搞了一个邮箱和验证码的登录；到中午没睡，下午和晚上精力明显跟不上，特别是碰到初始化环境报错更是一筹莫展，更别提进展了。

一：今日完成

1）一个controller里面的重要方法

/**

* 

* @param model

* @return

* @throws Exception

*/

@RequestMapping("/signin")

public ModelAndView signin(String userName, String passWord, String email, String captcha, HttpSession httpSession)

throws Exception {

ModelAndView modelAndView = new ModelAndView();

// 如果验证码不正确

if (!isCaptcha) {

modelAndView.addObject("info", "<span class='help-inline' style='color: #ff0000'>验证码不正确！</span>");

modelAndView.setViewName("reg");

return modelAndView;

}

// 创建新的用户

User user = new User();

user.setUserName(userName);

user.setEmail(email);

user.setPassWord(MD5.getMD5(passWord));

user.setRegTime(new Date());

user.setStatus((byte) 0);

// UserReg注册用户

userRegService.reg(user);

// 设置传到前台的信息和视图名称

// 设置session

modelAndView.setViewName("redirect:index.jsp");

httpSession.setAttribute("status", user.getStatus());

httpSession.setAttribute("userName", userName);

httpSession.setAttribute("email", email);

httpSession.setAttribute("phone", user.getPhone());

httpSession.setAttribute("regTime", user.getRegTime());

return modelAndView;

}

二：明日计划

希望能解决环境报错

三：疑难问题

见下面的代码报错

四：思考总结

导入过大大小小几十个项目，对于修改配置也很有心得，不过还是会碰到一些让人头疼的项目，特别是没有文档的。
