Spring data mongodb auditing not working.. (Java config)

Question

i'm currently using Spring data mongodb 1.6.0-RELEASE and i know it has auditing feature. I put @EnableMongoAuditing annotation on top of my configuration class. And my bean is below:

@Document
public class MyBean{

@Id
private AnotherCustomBean anotherCustomBean = new AnotherCustomBean();

@CreatedDate
private Date creationDate;

@LastModifiedDate
private Date lastModifiedDate;

.
.
.

When i save this bean with mongoTemplate.save(myBean); it's not setting created date and last modified date...And it has no errors.

Any help would be appreciated,

Thanks.

Answer 1

The actual problem was the @Id annotation. To use spring auditing properly, you have to define an ObjectId (null for new saved objects), thats how spring decide @LastModifiedDate and @CreatedDate

Afterwards, i found a way to make it possible use custom beans on @Id by implementing Auditable<String,String>

Thanks to @Felby:

I found that the @Id field needed to be null at the time of save() only for the @CreatedDate and @CreatedBy annotations. The @LastModifiedDate and @LastModifiedBy fields worked regardless of whether the @Id field was initialized or not.
