Learn to find JPA entities by ID or name using EntityManager.find(), JPQL queries, named queries, Criteria API, and Spring Data repository methods. JPA merge and persist: What’s Difference? In JPA, use merge when dealing with detached entities; and use persist to explicitly add a new enti...
The decryptFields method is annotated with the JPA @PostLoad annotation, so the JPA provider is going to call this method after fetching the entity. Therefore, we are going to use the decryptFields method to decrypt the attribute values of the UserDetails object. The CryptoUtils class is locat...
Actually I don't think you can ignore dataSources.xml, because if you have configured some JPA/ORM persistence checking in your project, then the .iml file will contain those references, which appear to reference structures in sqlDataSources.xml which reference structures in dataSo...
