Java – what settings do you need to make to use jsr-303 annotations in spring?

I downloaded spring 3 and put it on my classpath, but I couldn't import the @ valid annotation However, I can import other spring 3 Notes (such as @ controller) What jar is @ valid? Where and what package?

Editor: This is a JSR - 303 comment What does this mean and how to get it?

Solution

Missing javax validation.

You will find a jar here If you use maven, it depends on:

<dependency>
  <groupId>javax.validation</groupId>
  <artifactId>validation-api</artifactId>
  <version>1.0.0.GA</version>
</dependency>

To verify the actual work, you also need an implementation, such as hibernate validator Maven dependency:

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-validator</artifactId>
  <version>4.0.2.GA</version>
  <scope>runtime</scope>
</dependency>

JSR reference means that this is the standard for Java community process development, especially JSR number 303
