I am working on a project where I need to create history of particular table automatically. I have used #Audited annotation for it but it's creating duplicate data in table.
I am running out of space due to duplicate data.Even EclipseLink is not sloving my problem.
You tagged your question with Hibernate, but if switching to Eclipselink would be an option for you, be sure to check out the History Policy feature of Eclipselink. It allows automatic historization of data.
Please check Hibernate Envers.
This component integrates with JPA and Hibernate, and takes care of maintaing a revision history for any #Audited annotated Entity.
There are some guides on the net:

i am creating a maven multimoduled project one of the module for the hibernate entity only , issue is two services/api/maven_project are using same module , but one requires auditing but other dont , how i can keep my code intact (means ,without changing or removing #Audited annotation) , how to enable or disable envers auditing at run time or compile time,
because after everything i have tried auditing is working for both api
i have tried
spring.jpa.properties.hibernate.integration.envers.enabled=false
spring.jpa.properties.hibernate.listeners.envers.autoRegister=false
spring.jpa.properties.hibernate.envers.autoRegisterListeners=false
hibernate.integration.envers.enabled=false
hibernate.listeners.envers.autoRegister=false
hibernate.envers.autoRegisterListeners=false
As per buræquete's answer
spring.jpa.properties.hibernate.integration.envers.enabled=false
Would do the job.
"Non-Spring Data JPA" Hibernate properties are configured through
spring.jpa.properties.hibernate.*
In my case, i have a dependency to a module that implementing envers in its domains (its domains were annotated with #Audited). When i imported that module in my pom.xml and run my app, envers automatically creating audit tables based on its domains. My question, how can i prevent Envers for creating audited tables after the domains were annotated with #Audited? Is there any solution like adding a configuration in application.properties file or something like that?
org.hibernate.envers.table_creation = false
If you're importing a dependency that uses Envers but you do not require the tables or its functionality in your environment, you can easily disable Envers via a simple hibernate setting
hibernate.integration.envers.enabled=false
This should prevent Envers from bootstrapping and building any envers schema and it should also prevent the event listeners from being registered when entity model events fire where we track changes and generate the audit entries.
I'm trying to migrate an application from Hibernate 3.4.0.GA to Hibernate 5.1, and after complete the required changes on java code, when I deploy the application I'm watching how Hibernate is trying to create HT_ tables (global temporary), one for each #Inheritance annotated entity.
Searching on Google I've found why the tables are being created.
But in my case we are not allow to change de database to add new tables.
My Inheritance model only has one level of Inheritance and its simple, example
Does anyone knows any alternative representation for a hierarchical table structure that I can use to avoid the HT_ tables creation, or some Hibernate configuration to archive the same purpose?.
I can change the inheritance hierarchy on our entities or the Hibernate configuration. I can also asume an exception on deploy caused by the non creation of the tables if it´s non blocking for the rest of the deploy.
Thank you in advance.
UPDATE 1: New info from Hibernate official forum.
UPDATE 2: The Bug was fixed
UPDATE 3: A blog entry explaining different bulk Strategies related to the issue
As in update one on this link is more info from Hibernate official forum with a possible solution.
UPDATE: Link with the solution
If you use Oracle Database with Spring and not sure where to define property for hibernate can do the following.
Add
spring.jpa.properties.hibernate.hql.bulk_id_strategy: org.hibernate.hql.spi.id.inline.InlineIdsInClauseBulkIdStrategy
In application.yml file from resource folder.
I want to use a many-to-many relation between System & Device. I want the system to know its devices order.
I've seen here that I can do it using #OrderColumn.
How can I do it using hibernate xml configuration instead of annotation?
If you're using Hibernate you could try with
sort="unsorted|natural|comparatorClass"
order-by="column_name asc|desc"
as attributes of your relatonship declaration
#OrderColumn is the JPA annotation introduced in JPA 2.0. This works as an additional feature if we work hibernate through JPA. There is no equivalent replacement in hibernate who work with hibernate directly.
I have been looking at Hibernate Envers for entity auditing. I'm using EclipseLink but I'd like something similar.
I've seen some implementations that involve creating a SessionCustomizer to handle some of the persistence of auditing data. I'd really like something like Hibernate where I can simply annotate the entity and have the same effect.
Unfortunately, EclipseLink doesn't have a feature which covers auditing out-of-the-box.
We use a SessionEventListener to intercept a flush or commit and use the calculated changeset for inserting the auditing data into audit tables.
There is support for auditing of entities in EclipseLink. They call it History.
