我正在尝试使用Spring JPA提供的NamedStoredProcess dureQuery调用用Postgresql编写的存储过程。以下是代码片段。
EntityMovement.java
@Entity
@Table(name = "entity_movement")
@NamedStoredProcedureQueries({
@NamedStoredProcedureQuery(name = "near_by_entities",
procedureName = "near_by_entities",
parameters = {
@StoredProcedureParameter(mode = ParameterMode.IN, name = "location", type = String.class),
@StoredProcedureParameter(mode = ParameterMode.IN, name = "radius", type = Double.class),
@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, type = void.class)
})
})
public class EntityMovement implements Serializable{
//Fields
//Getters and Setters
}
实体运动知识库
@Repository
public interface EntityMovementRepository extends JpaRepository<EntityMovement, Entity>{
@Procedure(name = "near_by_entities")
public List<EntityMovement> nearByEntities(@Param("location")String location,@Param("radius")double radius);
}
正在呼唤
List<EntityMovement> entityMovements= entityMovementRepository.nearByEntities(location, radius);
存储过程
查询被简化
CREATE OR REPLACE FUNCTION public.near_by_entities(
location character varying,
radius double precision)
RETURNS refcursor
LANGUAGE 'plpgsql'
AS $BODY$
DECLARE ref refcursor;
BEGIN
OPEN ref FOR SELECT * FROM public.entity_movement;
RETURN ref;
END
$BODY$;

我是Spring JPA和它的注释的新手。参数的名称在@StoredProcess dureParameter
中明确提到,并且在存储库函数中的@参数
中也使用了相同的名称。这似乎是一个非常直接的错误消息,因为它说我使用命名参数而不是位置参数,并且我错过了一些非常明显的东西。但是我无法在任何论坛中找到任何解决方案。任何帮助都将不胜感激。谢谢!!
编辑-添加表格结构
创建表 public.entity_movement ( 实体 bigint 不为 NULL, 位置地理位置不为 NULL, movement_time时间戳,时区不为 NULL, 约束 pk_entity 主键(实体), 约束 fk2sd7ux7x1atbbpdl4y0lwc9la 外键 (实体) 引用 public.entity (id) 匹配 简单 更新 时无操作 删除时无操作,约束 fk_entity 外键(实体) 引用 public。实体 (id) 匹配 更新时简单 删除级联上无操作 )
根据jpa2.1的spring-data jpa示例,使用存储过程
spring数据示例
对存储库方法的调用表示两种不同的解释,一种是显式映射注释元数据,另一种是从存储库派生过程元数据。
调用UserRepository.plus1BackedBy的其他名称存储过程(...)将使用在User域类上声明的元数据执行存储过程plus1inout。
UserRepository.plus1inout(...) 将从存储库派生存储过程元数据,并默认为位置参数绑定,并期望支持存储过程的单个输出参数。
在这里,这可能是对近ByEntities的调用通过从repo派生来解决的情况,这是位置的?
为了进行尝试,我们可以更新注释中的名称
@NamedStoredProcedureQuery(name = "near_by_entities",
到
@NamedStoredProcedureQuery(name = "EntityMovement.nearByEntities",
以及
@Procedure(name = "near_by_entities")
public List<EntityMovement> nearByEntities(@Param("location")String location,@Param("radius")double radius);
到
@Procedure(name = "EntityMovement.nearByEntities")
public List<EntityMovement> nearByEntitiesNamed(@Param("location")String location,@Param("radius")double radius);
打电话会是
List<EntityMovement> entityMovements= entityMovementRepository.nearByEntitiesNamed(location, radius);
能否尝试给out参数添加一个名称:
@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, name = "out", type = void.class)
问题的根源是您混合了命名和位置参数。命名存储过程查询3.10.17.1节中的JPA 2.1规范指出,这种用法会导致未定义的行为:
如果使用参数名称,则参数名称用于绑定参数值和提取输出值(如果参数是INOUT或OUT参数)。如果未指定参数名称,则假定使用位置参数。未定义命名参数和位置参数的混合。
这也是为什么Hibernate在确定参数策略时只检查参数定义#L156
中的第一个存储过程参数的原因。
“找到与位置参数关联的命名存储过程参数”错误消息有点误导,因为在过程中,当参数策略被命名但参数是位置的时,使用了相同的错误消息,反之亦然。您的案例中的错误消息应该是:“找到与命名参数关联的位置存储过程参数”(因为在您的案例中,策略被定义为命名,但您的最后一个
REF_CURSOR
参数是位置的)。
要解决这个问题,我们可以向
REF_CURSOR
参数添加一个名称:
@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, name = "out", type = void.class)
但不幸的是,这将导致另一个(误导性的)错误消息:
org.springframework.orm.jpa.JpaSystemException: PostgreSQL supports only one REF_CURSOR parameter, but multiple were registered
尽管只注册了一个< code>REF_CURSOR
参数,我们还是收到了一条关于注册了多个参数的错误消息。异常由< code > postgrescalablestatementsupport # L66 引发,事实上,当定义了< code>REF_CURSOR参数时,其< code > renderCallableStatement()方法包含几个关于要求的有用信息:
此外,在renderCallableStatement()
方法中的注释中明确指出,不允许混合命名参数和位置参数。
所以我们应该删除提供的名称:
@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, type = void.class),
@StoredProcedureParameter(mode = ParameterMode.IN, type = String.class),
@StoredProcedureParameter(mode = ParameterMode.IN, type = Double.class)
由于目前Spring数据不支持覆盖位置参数映射(仅命名参数映射),并且我们的第一个参数是<code>REF_
InvalidDataAccessApiUsageException: Parameter value [location] did not match expected type [void (n/a)]
因此,不能再使用< code>@Procedure,但作为一种解决方法,我们可以创建并实现一个单独的< code > entitymovementrepository with Procedure 接口,并手动进行映射:
public interface EntityMovementRepositoryWithProcedure {
List<EntityMovement> nearByEntities(String location, double radius);
}
@Repository
public interface EntityMovementRepository extends JpaRepository<EntityMovement, Integer>, EntityMovementRepositoryWithProcedure { }
public class EntityMovementRepositoryImpl implements EntityMovementRepositoryWithProcedure {
@PersistenceContext
private EntityManager em;
@Override
public List<EntityMovement> nearByEntities(String location, double radius) {
StoredProcedureQuery nearByEntities em.createNamedStoredProcedureQuery("near_by_entities");
nearByEntities.setParameter(2, location);
nearByEntities.setParameter(3, radius);
return nearByEntities.getResultList();
}
}
此外,在使用PostgreSQL < code > REF _ CURSOR 时必须禁用自动提交,否则在调用存储过程时将引发以下异常:
PSQLException: ERROR: cursor "<unnamed portal 1>" does not exist
这里有一个完整的示例:https://github.com/sandor-balazs/example/tree/master/spring-data-postgresql-refcursor.
