In this tutorial, I am going to show you how to use JOIN in custom spring JPA queries.
The join is always on the id column.
@Query("select distinct user from User user JOIN user.address addr WHERE addr.id = 1;")
User getUserById(@Param("addressId") Long addressId);Multiple Joins
@Query("select distinct user from User user JOIN user.account acct JOIN acct.paymentMethod pm WHERE pm.id = 1;")
User getUserById(@Param("pmId") Long pmId);
