java - 我可以在接口(interface)扩展 CrudRepository 中定义哪些方法列表

Question

每个使用 Spring Data JPA 的示例都包含此方法:

   public interface PersonRepository extends CrudRepository<Person, Long> {

        List<Person> findByLastName(@Param("name") String name);

    }

是否有其他方法可以 JPA+Hibernate 在运行时实现然后 findByVarialbleName 我可以在存储库中定义它？

Answer 1

请引用query method document
一些示例查询方法:

public interface PersonRepository extends Repository<User, Long> {

  List<Person> findByEmailAddressAndLastname(EmailAddress emailAddress, String lastname);

  // Enables the distinct flag for the query
  List<Person> findDistinctPeopleByLastnameOrFirstname(String lastname, String firstname);
  List<Person> findPeopleDistinctByLastnameOrFirstname(String lastname, String firstname);

  // Enabling ignoring case for an individual property
  List<Person> findByLastnameIgnoreCase(String lastname);
  // Enabling ignoring case for all suitable properties
  List<Person> findByLastnameAndFirstnameAllIgnoreCase(String lastname, String firstname);

  // Enabling static ORDER BY for a query
  List<Person> findByLastnameOrderByFirstnameAsc(String lastname);
  List<Person> findByLastnameOrderByFirstnameDesc(String lastname);
}

Spring Data JPA 还支持 deleteBy、count
