I would like to do something like this (in Spring Data JPA) in a repository interface:
interface myRepository extends JpaRepository<A, Long> {
@Query("select a from A a where a.x = :x")
A findFirstBySomeCondition(int x);
}
But I only need the first result. (Edited: The actual query condition is much complex so I would prefer to use @Query instead of findFirst or findTop...)
I don't want to use criteria api, because it's verbose.
I don't want to use the the native query cause I will have to compose the query string manually.
So, is there an solution left though, given the restricted requirement above?
Thanks!
The results of query methods can be limited via the keywords first or top, which can be used interchangeably. An optional numeric value can be appended to top/first to specify the maximum result size to be returned.
interface myRepository extends JpaRepository<A, Long> {
@Query("select a from A a where a.x = :x")
Page<A> findFirstBySomeCondition(@Param("x") int x,Pageable pageable);
}
Impletation Class:
Page<A> results = repository.findFirstBySomeCondition(x,new PageRequest(0, 1));
A object = results.getContent.get(0);
