Custom JPA methods Using @Query and @NamedQuery
Explore how to implement custom JPA methods using @Query and @NamedQuery annotations in Spring Data JPA. Understand writing user-defined queries with parameters and integrating named queries to manage database retrievals more effectively within your repositories.

However, when using a combination of more properties, the method name can get very long, and complexity increases. Therefore, Spring Data JPA allows custom methods in repositories to be created with user-defined queries using the @Query ...
