Java By Source

In my previous article Spring Data JPA Auditing: Saving CreatedBy, CreatedDate, LastModifiedBy, LastModifiedDate automatically , I have discussed why Auditing is important for any business application and how we can use Spring Data JPA automate it. I have also discussed how Spring Data uses JPA’s EntityListeners and callback methods to automatically update CreatedBy , CreatedDate , LastModifiedBy , LastModifiedDate properties. Well, here in this article I am going dig a little bit more and discuss how we can use JPA EntityListeners to create audit logs and keep information of every insert, update and delete operation on our data. I will take the File entity example from the previous article and walk you through the necessary steps and code portions you will need to include in our project to automate the Auditing process. We will use Spring Boot, Spring Data JPA (Because it gives us complete JPA functionality plus some nice customization by Spring), MySql to demonstrate this. We wi...

In any business application auditing simply means tracking and logging every change we do in the persisted records which simply means tracking every insert, update and delete operation and storing it. Auditing helps us in maintaining history records which can later help us in tracking user activities. If implemented properly auditing can also provide us similar functionality like version control systems. I have seen projects storing these things manually and doing so become very complex because you will need to write it completely by your own which will definitely require lots of code and lots of code means less maintainability and less focus on writing business logic. But why should someone need to go to this path when both JPA and Hibernate provides Automatic Auditing which we can be easily configured in your project. And here in this article, I will discuss how we can configure JPA to persist CreatedBy, CreatedDate, LastModifiedBy, LastModifiedDate columns automatically for any ...
