Problems with Java 17 and Hibernate's @DynamicUpdate Not Reflecting Changes on Detached Entities
I'm attempting to set up I'm having a hard time understanding I've spent hours debugging this and This might be a silly question, but I'm working with an scenario where Hibernate's `@DynamicUpdate` annotation doesn't seem to work as expected with detached entities in my Java 17 application. I've set up my entity with the annotation, but when I make changes to the object and attempt to save it back to the database, the SQL generated does not include the updated fields. Instead, it tries to insert all fields again, leading to primary key constraint violations. Hereβs a simplified version of my entity: ```java @Entity @Table(name = "users") @DynamicUpdate public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; private String name; private String email; // Getters and Setters } ``` When I fetch this entity, modify the `name` field, and then call `session.update(user)`, I expect only the changed field to be included in the SQL update statement. However, I see the following log output: ``` Hibernate: insert into users (id, name, email) values (?, ?, ?) ``` I have tried: - Ensuring the entity is attached to the session before the update call. - Using `session.merge(user)` instead, but it still results in the same behavior. - Checking for cascade types that might affect how the entity is managed. Furthermore, I also confirmed that the `@DynamicUpdate` annotation is indeed present. I am using Hibernate 5.6.0.Final along with Spring Boot 2.6.3. Any help in debugging this scenario would be greatly appreciated! Is there a better approach? I'm using Java LTS in this project. This is my first time working with Java LTS. Is this even possible? I'm working on a service that needs to handle this.
