Searching An object from @ElementCollection

Question

I am using Spring Data JPA.

I an entity like this

public class A {

    @CollectionTable(name = \"B_ITEMS\", joinColumns = @JoinColumn(name = \"B_ID\"))
         


        

Answer 1

Instead of using @Query like in @Zeromus answer you can also define it by method name (findByElementCollectionProperty_NestedProperty):

public interface ARepo extends JPARepository {

    List findByBs_Prop1(String prop1);
}

More information how SpringData resolves nested Properties can be found under:
