I try to use @Valid annotation, but eclipse always gives the "Valid cannot be resolved to a type" error. I m using the spring3 library.
我尝试使用@Valid 注释，但 eclipse 总是给出“Valid 无法解析为类型”错误。我正在使用 spring3 库。
I have imported hibernate-validator-4.1.0.Final.jar into my WEB-INF/lib directory. however, this does not solve the problem.
我已将 hibernate-validator-4.1.0.Final.jar 导入到我的 WEB-INF/lib 目录中。然而，这并不能解决问题。
Any help is appreciated!

@Validbelongs to JSR-303. You can get it via maven using this dependency:
@Valid属于JSR-303。您可以使用此依赖项通过 Maven 获取它：
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
Or you can download it from this page.
或者你可以从这个页面下载它。

As far as I remember the @Validannotation is part of the validation-api JAR which you can find in the lib directory of the Hibernate Validator, as you have already downloaded the Hibernate implementation. The @Validis a part of the javax.validation annotation API. You can add this JAR to your class path to be able to properly reference the annotation.
据我所知，@Valid注释是验证 API JAR 的一部分，您可以在 Hibernate Validator 的 lib 目录中找到它，因为您已经下载了 Hibernate 实现。这@Valid是 javax.validation 注释 API 的一部分。您可以将此 JAR 添加到您的类路径中，以便能够正确引用注释。
