add()代码

@At
	public Object add(@Param("..") User user) {
		NutMap re = new NutMap();
		String msg = checkUser(user, true);
		if (msg != null) {
			return re.setv("ok", false).setv("msg", msg);
		}
		user.setCreateTime(new Date());
		user.setUpdateTime(new Date());
		user = dao.insert(user);
		return re.setv("ok", true).setv("data", user);
	}

			$.ajax({
				url : base + "/user/add",
				type : "POST",
				data : $('#loginForm2').serialize(),
				dataType : "json",
				success : function(data) {
					console.log(data);
					if (!data.ok) {
						alert(data.msg);
					} else {
						alert(data.data.id);
					}
				}
			});
