Hibernate scenarios to update entity with @Version field, causing OptimisticLockException
I'm integrating two systems and I'm testing a new approach and I've searched everywhere and can't find a clear answer. I'm working with an scenario with Hibernate when trying to update an entity that includes an `@Version` field for optimistic locking... My entities are set up as follows: ```java @Entity public class Product { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; private Double price; @Version private Long version; // Getters and Setters } ``` In my service layer, I have a method that retrieves a `Product` by ID, modifies it, and then updates it: ```java @Transactional public void updateProduct(Long id, String newName, Double newPrice) { Product product = productRepository.findById(id).orElseThrow(() -> new EntityNotFoundException("Product not found")); product.setName(newName); product.setPrice(newPrice); productRepository.save(product); } ``` However, when I call this method, I occasionally get an `OptimisticLockException` that states: ``` org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [com.example.Product#1] ``` I suspect this is happening because two transactions are trying to update the same `Product` simultaneously, but I am unsure how to handle it properly. I have tried adding a retry mechanism but that hasn't resolved the question completely. I'm using Spring Boot 2.5.4 with Hibernate 5.5.7. What is the best way to manage updates on entities with an `@Version` field to prevent this exception? Should I implement some retry logic or is there a more effective strategy? Any insights would be greatly appreciated! This is part of a larger web app I'm building. I'd really appreciate any guidance on this. Thanks for taking the time to read this! I recently upgraded to Java LTS. Cheers for any assistance! I'm working with Java in a Docker container on CentOS. The stack includes Java and several other technologies.
