查找6以下的Hibernate版本并重试，使用@ModelAttribute可以将表单的输入映射到bean，而api 2.0的6.0版本可能会导致bean出现一些问题。我建议您查看此主题以清楚地了解这些问题：：

我添加了您所做的常规工作（pom中的库、@Valid on RequestBody等）

Spring文档（和许多博客）让它变得微妙的是，Spring寻找一个退出点来抛出错误，但如果该退出点不存在，它将以404作为回复。在阅读了大量内容（尤其是本文）之后，添加此类使Spring能够识别@Valid并找到一个退出点来抛出错误

    @RestControllerAdvice
    @Order(1) 
    public class RestControllerExceptionHandler {

    @RequestMapping(value = { "error/404" }, method = RequestMethod.GET)
    @ExceptionHandler(Exception.class)
    public String handleUnexpectedException(Exception e) {
        return "views/base/rest-error";         
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public String handlemethodArgumentNotValid(MethodArgumentNotValidException exception) { //
        // TODO you can choose to return your custom object here, which will then get transformed to json/xml etc.
        return "Sorry, that was not quite right: " + exception.getMessage();
    }

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(ConstraintViolationException.class)
    public String handleConstraintViolation(ConstraintViolationException exception) { //
        // TODO you can choose to return your custom object here, which will then get transformed to json/xml etc.
        return "Sorry, that was not quite right: " + exception.getMessage();
    }

您可以用表单显示jsp页面吗？您还应该将jsp页面放在web inf文件夹下。请改用hibernate validator 5.4.1最终版本。版本6适用于bean验证api 2.0您可以用表单显示jsp页面吗？您还应该将jsp页面放在web inf文件夹下。请改用hibernate validator 5.4.1最终版本。版本6用于bean验证api 2.0
