总结一下,Spring Data JPA中自定义命名规则中,如何自定义排序规则


Spring Data JPA中自定义命名规则中,如何实现,自定义排序输出


代码如下

// findByName,会有重名的,返回list,默认是按照ID,返回,现自定义排序规则,按照入学时间升序排序
	@GetMapping("/findByName2")
	public ResultBean getbyName2(String name) {
		return ResultBean.ok(stu2Service.findByAndSort(name));
	}
public interface Stu2Service {
	List findByAndSort(String name);
}
public interface Stu2Repository extends JpaRepository, JpaSpecificationExecutor {

	@Query("select u from Stu2 u where u.name=?1")
	List findByAndSort(String name, Sort sort);
}
@Override
public List findByAndSort(String name) {
	return stu2Repository.findByAndSort(name, Sort.by(Direction.ASC, "admissionTime"));
	}

启动项目,访问 http://ip:port/xxx//findByName2?name=xx

JPA生成的SQL语句为

SELECT
	stu2x0_.id_ AS id_1_1_,
	stu2x0_.admission_time AS admissio2_1_,
	stu2x0_.age_ AS age_3_1_,
	stu2x0_.created_by AS created_4_1_,
	stu2x0_.hobbies_ AS hobbies_5_1_,
	stu2x0_.name_ AS name_6_1_,
	stu2x0_.phone_ AS phone_7_1_,
	stu2x0_.sid_ AS sid_8_1_,
	stu2x0_.summary_ AS summary_9_1_
FROM
	ls_stu2 stu2x0_
WHERE
	stu2x0_.name_ =?
ORDER BY
	stu2x0_.admission_time ASC
