Does Spring Data REST support JPA @Version?

由 心不动则不痛 提交于 2019-12-10 03:04:10
问题 Can I use JPA @Version with Spring Data REST? In Spring Data REST 1.1.0.M1 I can configure the repo exporter to expose the entity ID, which as it happens also exposes @Version -annotated fields. So I thought that if I tried to PUT an entity with some old version number, I'd get the OptimisticLockException . But that doesn't occur. Instead the PUT succeeds (including data updates), except that the version number is always strictly incremented instead of being whatever old version I set it to.

问题 I have my Entities with Spring Data JPA, but to generate stats about them, I use jOOQ in a Spring @Repository .

问题 I have a very simple Spring Data REST project with two entities, Account and AccountEmail. There's a repository for Account, but not for AccountEmail.

Exposing link on collection entity in spring data REST

由 你离开我真会死。 提交于 2019-12-08 22:22:30
问题 Using spring data REST I have exposed a ProjectRepository that supports listing projects and performing CRUD operations on them. When I go to http://localhost:8080/projects/ I get the list of projects as I expect.
