spring-data-jpa 的@Query注解的使用

// ------------------------------------ 使用 @Query 注解
// 没有参数的查询
@Query("select p from Person p where p.id = (select max(p2.id) from Person p2)")
Person getMaxIdPerson();

//使用 ? 和数字代表传入的参数
@Query("select p from Person p where lastName=?1 and email=?2")
Person readPersonByLastNameAndEmail(String lastName,String email);
//使用 :代表传入的参数
@Query("select p from Person p where email=:email and  lastName=:name")
Person readPersonByLastNameAndEmailThroughName(@Param("name") String lastName,@Param("email") String email);

// 使用 like
@Query("select p from Person p where lastName like ?1")
Person readPersonByLike(String likeName);

// @Query 注解支持使用百分号
@Query("select p from Person p where lastName like %?1%")
Person readPersonByLike2(String likeName);

// @Query 注解支持使用百分号
@Query("select p from Person p where lastName like %:lastName%")
Person readPersonByLike3(@Param("lastName")String name);

// 使用原生的 SQL
@Query(value="select * from jpa_person p1 where p1.last_name like %:lastName%",nativeQuery=true)
Person getPersonUsingOriginSQL(@Param("lastName")String lastName);
