//提交处理
@At("/submit")
public View submit(@Param("::user.")User user,@Param("::employeeInfo.")EmployeeInfo ei){
//为用户添加时间戳
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
user.setTime(sdf.format(date));
//将提交的数据存入数据库中
if(Strings.isEmpty(user.getId())){ //若id为空，则该操作为添加新用户，插入信息
user.setEmployeeInfo(ei);
dao.insertWith(user,"ei");
}else{ //若id不为空，则该操作为编辑用户，更新信息
dao.updateWith(user,"ei");
}
return new ServerRedirectView("/system/admin/index");
}

执行这段操作后，console显示

For example:> "INSERT INTO users(id,username,password,e_id,r_id,time) VALUES('a349d7ab-d413-40d3-b43e-9ff771b2ddd2','admin','123456',NULL,'8acffc23-71e8-479f-9e77-a7db75b8357d','2018-03-29 15:12:34') "

进行几次验证，user和ei能够获取页面的值，在进行插入的时候，没有成功，程序也没有报错，这是为什么呢？
