Spring javax.validation problem

In my application with spring framework, I have this import which it couldn't find

 import javax.validation.Valid;

Thing is I already have that javax.jar in the classpath. So my question is is there a different version of javax.jar that has validation package or I need any other jar files? I couldn't find any javax.jar that has v开发者_如何学运维alidation package on the internet. So please give me a link if you know any. Thanks in advance!

You're looking for javax.validation:validation-api.

Also, as Amir mentioned, if you've found stackoverflow useful, accept some answers. People will be more inclined to help out.

javax.validation.* is part of jsr-303 which needs to be downloaded separately here.

If you are using maven, just add the external dependency in your pom.xml

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>
