如何将自定义部分添加到 spring-data 存储库方法名称？

Question

I have a repository and want to add two methods that perform "the same" operation (eg find by id), but one method eagerly fetches some data. Is it possible to add a custom part to the name to allow for both methods to exist and to inform the caller about what the methods do?

For example:

@Repository
public interface UserRepository {

    Optional<User> findById(UUID id);
    
    @EntityGraph(attributePaths = {"posts", "comments"})
    Optional<User> findByIdEagerlyFetchingPostsAndComments(UUID id);
}

Answer 1

You need to place method marker ( EagerlyFetchingPostsAndComments in your case) between (find|read|get|query|search|stream) and By , for example:

@EntityGraph(attributePaths = {"posts", "comments"})
Optional<User> findEagerlyFetchingPostsAndCommentsById(UUID id);
