Spring Data @CreatedDate annotation doesn't work for me

Question

I am working on project where I use Spring Data. I wanted to fill in creationTime field using @CreatedDate annotation instead using method with

Answer 1

I may have been in a similar situation where I wanted the Spring Data JPA @CreatedDate annotation to work, but had no need for the user-level auditing that is otherwise described in their documentation.

To get the annotation-based auditing to work, I had to nonetheless add a class to my project that implemented org.springframework.data.domain.AuditorAware. This is odd because you don't actually seem to use the value returned from the getCurrentAuditor() method that you'll be implementing; mine just returns null.

public class NullAuditorBean implements AuditorAware {

    @Override
    public Object getCurrentAuditor() {
        return null;
    }
}

I then needed to reference my "null object" AuditorAware implementation in an entry in my applicationContext to activate the JPA auditing. I had to make sure I did this before the line that specifies the jpa:repositories. This looks something like:

<bean id="auditorBean" class="your.package.subbed.here.NullAuditorBean"/>
<jpa:auditing auditor-aware-ref="auditorBean"/>

I also had to add an orm.xml file, and needed to formally reference it as a property of my entityManagerFactory bean, like so:

<property name="mappingResources">
    <value>META-INF/orm.xml</value>
</property>

Make sure this META-INF/orm.xml entry is stored with your compile output (mine is in my WAR under WEB-INF/classes.

That orm.xml file, for the record, contained some boilerplate, which can be found in the answer to this related question.

It was a fair amount of work when I got this working. You may prefer your previous working solution!

Answer 2

This question is quite old, but still relevant. For me the key was this, from the documentation

Since Spring Data MongoDB 1.4 auditing can be enabled by annotating a configuration class with the @EnableMongoAuditing annotation.

For example:

@Configuration
@EnableMongoAuditing
class Config {

  /**
   * Optional, depending on your needs
   */
  @Bean
  public AuditorAware<AuditableUser> myAuditorProvider() {
      return new AuditorAwareImpl();
  }
}

Or, in XML:

<mongo:auditing/>
