Spring如何在Boot中调用存储过程？

Question

查询多个删除的存储过程会产生如下所示的错误消息。

CREATE OR REPLACE PROCEDURE delete_dim_page(_page_id bigint)
 LANGUAGE plpgsql
 AS $procedure$
    
begin
   delete from page_catalog where page_type_id = _page_id;
   delete from page_type where page_type_id = _page_id;
END;
$procedure$
;

//实体类

@NamedStoredProcedureQuery(
    name = "firstProcedure",
    procedureName = "delete_dim_page",
    parameters = {
        @StoredProcedureParameter(
            mode=ParameterMode.IN,
            name="_page_id",
            type = Long.class
        )
    }
)

//service.java

    StoredProcedureQuery query = em.createNamedStoredProcedureQuery("firstProcedure");
    query.setParameter("_page_id", pageTypeId);
    query.execute();

产量

ERROR: delete_dim_page1(bigint) is a procedure
Hint: To call a procedure, use CALL.

在 Spring Boot 中调用存储过程的推荐方法是什么？

Answer 1

我想你正在使用 spring 数据 jpa。您可以只创建一个 jpa 存储库，然后使用这样的注释调用您的过程：

public interface PageCatalogRepository extends JpaRepository<PageCatalogEntity , Long> {
    @Query(value = "CALL firstProcedure(:page_id);", nativeQuery = true)
    void deletePageCatalogById(@Param("page_id") Long page_id);
}

您可以在这里找到其他过程调用方法https://www.baeldung.com/spring-data-jpa-stored-procedures

Answer 2

另一种方法是使用注解@Procedure

import org.springframework.data.jpa.repository.query.Procedure;
...
public interface PageCatalogRepository extends JpaRepository<PageCatalogEntity , Long> {
   @Procedure
   public String firstProcedure(Long page_id);
}
