validation

替換UserBean.java裏的private爲

@NotEmpty(field="用戶ID",  message="{errors.required}")

private String userId;

@NotEmpty(field="用戶姓名",  message="{errors.required}")

private String userName;

@NotEmpty(field="用戶密碼",  message="{errors.required}")

private String password;

爲登錄，註冊，修改，添加條件

(Model model, HttpSession session, @Valid @ModelAttribute("userBean") UserBean userBean, BindingResult results) throws SQLException {

if (results.hasErrors()) {

log.info("內容驗證出錯");

return "register";}}

其中登錄中須建立新的實例對象 

UserBean userBean=new UserBean();

model.addAttribute("userBean",userBean);

對應的頁面中顯示內容需添加

<span th:if="${#fields.hasErrors('${userBean.*}')}"><span th:errors="${userBean.*}"></span></span>

<span th:text="${message}"></span>

注意驗證信息條件：

if(device.isNormal()) {
				return "mobile/alipay/distributorAlipayConfirm";
	    	} else {
	    		return "mobile/alipay/distributorAlipayConfirm";
	    	}
