java - 对象 ='auctionItem' 的验证失败

转载作者：塔克拉玛干更新时间：2023-11-02 19:50:49

当尝试提交我的表单以创建新拍卖时，浏览器中出现此错误:

Whitelabel Error Page:

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Thu Mar 30 21:00:15 BST 2017 There was an unexpected error (type=Bad Request, status=400) Validation failed for object='auctionItem'. Error count: 2

我似乎无法在我的日志中找到任何特定错误，因此我无法找到错误页面上显示的两个验证错误。在这一点上我很迷茫。希望有人能帮助我，这让我目前无法取得进步。

最佳答案

也许你错过了 Controller 中的“BindingResult ”。示例:

import org.springframework.validation.BindingResult; 

@RequestMapping(value = "/registration", method = RequestMethod.POST)
public String registration(
    @ModelAttribute("userlogin") @Valid LoginProfile userlogin,
    BindingResult userloginResult)
