Start Updating in hibernate

Updating in hibernate

In this case it is very handy because it includes: an embedded tomcat,’starter’ POMs to simplify your Maven configuration, and REST web services ready to use. Also you will find that a new table called REVINFO, which contains all the revisions information, has been created.

Not Blank; import com.fasterxml.jackson.annotation. This implementation is plugged in by Spring automatically at runtime.

For this purpose you will need to implement this 2 classes: The Revision entity is the class which contains the data that you would like to audit in each transaction.

It is mandatory that this class contains a revision number and a revision timestamp, either you can add these 2 fields manually or you can extend the Default Revision Entity class which already contains them.

Here is an example of my revision entity which extends Default Revision Entity and have an attribute for the username: Note that the class contains the @Revision Entity(User Revision Listener.class) annotation.

The revision listener is the class where you need to specify how to populate the additional data into the revision.

Here is an example of an audited java class: In this case we will automatically have in our database 2 tables, one called City and another one called City_AUD which will include all the city fields plus a revision identifier and a revision type (creation, update, delete).

If you have already configured Hibernate Envers into your project, now every time that you add or update an object into the database you will see that another row will be added to the audited table.

Please have a look to the following example: All the code used in this post is available in github.
