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

An approach could be to search a list of A objects for all the properties of B object. That means use filters for prop1, prop2 and prop3 together.

public interface ARepo extends PagingAndSortingRepository {
    List findByBsProp1AndBsProp2AndBsProp3(String prop1, String prop2, String prop3); 
}
