Spring JPA中的NamedStoredProcedureQuery錯誤 - 「找到與位置參數關聯的命名存儲過程參數」

Question

我想用Spring JPA提供的NamedStoredProcedureQuery調用Postgresql中編寫的存儲過程。以下是代碼片段。

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 

} 

EntityMovementRepository

@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); 

} 

調用

List<EntityMovement> entityMovements= entityMovementRepository.nearByEntities(location, radius); 

Stored Procedure

查詢被簡化

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 
$BODY$;

我新的春天JPA和它的註解。該參數的名稱在@StoredProcedureParameter中明確提到，並且@param在存儲庫功能中使用了相同的名稱。這看起來像是一個非常直接的錯誤信息，因爲它表示我使用的是命名參數而不是位置參數，並且我缺少一些非常明顯的東西。但我無法在任何論壇中找到任何解決方案。 任何幫助，將不勝感激。謝謝！！

編輯 - 添加表結構

CREATE TABLE public.entity_movement ( entity bigint NOT NULL, location geography NOT NULL, movement_time timestamp with time zone NOT NULL, CONSTRAINT pk_entity PRIMARY KEY (entity), CONSTRAINT fk2sd7ux7x1atbbpdl4y0lwc9la FOREIGN KEY (entity) REFERENCES public.entity (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE NO ACTION, CONSTRAINT fk_entity FOREIGN KEY (entity) REFERENCES public.entity (id) MATCH SIMPLE ON UPDATE NO ACTION ON DELETE CASCADE )

Answer 1

你可以嘗試將名稱添加到輸出參數：

@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, name = "out", type = void.class) 

Answer 2

中爲每個JPA2彈簧數據的JPA例子。 1使用存儲過程

spring-data-examples

表示對存儲庫方法調用的兩種不同解釋，一種是與註釋元數據顯式映射，另一種從存儲庫派生過程元數據。

調用UserRepository.plus1BackedByOtherNamedStoredProcedure（...）將使用在用戶域類上聲明的元數據執行存儲過程plus1inout。

UserRepository.plus1inout（...）將從存儲庫派生存儲過程元數據，並默認爲位置參數綁定，並期望後備存儲過程的單個輸出參數。

在這裏，這可能是這樣的情況下調用nearByEntities通過從回購得到解決，這是位置？

爲了得到一個嘗試，我們可以更新名稱中標註

@NamedStoredProcedureQuery(name = "near_by_entities", 

要

@NamedStoredProcedureQuery(name = "EntityMovement.nearByEntities", 

隨着

@Procedure(name = "near_by_entities") 
public List<EntityMovement> nearByEntities(@Param("location")String location,@Param("radius")double radius); 

要

@Procedure(name = "EntityMovement.nearByEntities") 
public List<EntityMovement> nearByEntitiesNamed(@Param("location")String location,@Param("radius")double radius); 

呼叫將

List<EntityMovement> entityMovements= entityMovementRepository.nearByEntitiesNamed(location, radius); 

Answer 3

問題的根源是，你混合命名和位置參數。 的JPA 2.1 specification在第3.10.17.1命名的存儲過程的查詢指出，這種用法導致未定義行爲：

如果使用參數名稱參數名稱用於該參數值綁定，並提取輸出值（如果參數是INOUT或OUT參數）。如果沒有指定參數名稱，則假定使用位置參數。命名參數和位置參數的混合是不確定的。

這也可能是Hibernate--確定參數策略時僅檢查ParameterDefinition#L156中的第一個存儲過程參數的原因。

「找到與位置參數關聯的已命名的存儲過程參數」錯誤消息有點令人誤解，因爲在ProcedureCallImpl#L423中，當參數策略被命名但參數是位置的並且相反的方式時，會使用相同的錯誤消息。在你的情況下的錯誤消息應該是這樣的：「找到與命名參數關聯的位置存儲過程參數」（因爲在你的情況下，策略被定義爲named，但最後的REF_CURSOR參數是位置的）。

爲了解決這個問題，我們可以將名稱添加到REF_CURSOR參數：

@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, name = "out", type = void.class) 

但不幸的是，這將導致另一場（誤導）錯誤信息：

org.springframework.orm.jpa.JpaSystemException: PostgreSQL supports only one REF_CURSOR parameter, but multiple were registered 

儘管只有一個已註冊REF_CURSOR參數我們收到一條關於註冊多個的錯誤消息。唯一的例外是PostgresCallableStatementSupport#L66拋出，事實上其renderCallableStatement()方法包含有關要求的一些有用的信息時，規定了一個REF_CURSOR參數：

• 它應該是第一個參數
• 參數策略必須是位置

並且還在renderCallableStatement()方法的評論中明確指出混合命名和位置參數是不允許的。

所以我們應該刪除所提供的名稱：

@StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, type = void.class), 
@StoredProcedureParameter(mode = ParameterMode.IN, type = String.class), 
@StoredProcedureParameter(mode = ParameterMode.IN, type = Double.class) 

由於目前春節數據不支持位置參數映射的首要（僅named parameter mapping）和我們的第一個參數是一個REF_CURSOR，我們得到了以下錯誤消息當彈簧數據試圖映射REF_CURSOR到存儲庫中的接口中定義的第一種方法參數：

InvalidDataAccessApiUsageException: Parameter value [location] did not match expected type [void (n/a)] 

所以@Procedure不能再被使用，但作爲一種解決方法，我們可以創建並實施一個單獨的EntityMovementRepositoryWithProcedure接口和做手工映射：調用存儲過程時，否則

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(); 
    } 
} 

而且autocommit has to be disabled when using PostgreSQL REF_CURSOR下，會引發異常：

PSQLException: ERROR: cursor "<unnamed portal 1>" does not exist 

一個完整的實例可以在這裏找到：https://github.com/sandor-balazs/example/tree/master/spring-data-postgresql-refcursor。
