Spring MVC验证抛出ConstraintViolationException

Question

我想验证bean类Articolo，它是模型类NewEditArticle的一个属性，它的实例在控制器中创建并传递给视图ArticleManager.jsp。

此视图是在SQL数据库中插入、更新或删除项目的表单。

我试图实现一个基于注释的验证系统，但由于某种原因它不起作用:例如，如果我提交表单时没有填充bean类中标记为NotEmpty/NotNull的字段，系统将抛出一个与验证相关的异常，但不会从BindingResult捕获任何内容。

根据我对错误消息的理解，验证在某种程度上是有效的，但是result.hasErrors()没有捕获任何内容，因此它不会返回显示错误消息的表单。

你知道问题出在哪里以及如何解决吗？

注意:我的配置中已经有了mvc:annotation-driven。

Answer 1

您似乎没有配置MessageValidation.properties，因此需要将MessageValidation.properties (或相关的配置文件)添加到类路径中以获取并填充错误消息，您可以查看here

Answer 2

最终，我在这里找到了解决方案：JSR-303 @Valid annotation (nested object) not working

在NewEditArticle类中的Articolo字段上添加@Valid注释就足够了，并且验证生效了。
