Spring Data JPA also provides options to write custom queries. The following snippet shows a simple example:
@Query("select u from User u where u.name = ?1") List<User> findUsersByNameUsingQuery(String name);
Important things to note are as follows:
- @Query: The annotation to define queries for repository methods
- select u from User u where u.name = ?1: Query to be executed. ?1 represents the first parameter
- findUsersByNameUsingQuery: When this method is called, the query specified is executed with the name as the parameter
