Question

我有一个存储过程，它接收输入列表然后输出结果集。使用的数据库是SQL Server 2008，JPA 2.1规范提供程序是Hibernate。

我的实体结构如下：

@NamedStoredProcedureQuery(name = "ModelSearchByModel",
        resultClasses = ModelSearchByModelEntity.class,
        procedureName = "SPR_ModelSearchByModel",
        parameters = {
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "RegionCode", type = String.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "BuildingCode", type = String.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "ProductCode", type = String.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "StatusCode", type = String.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MinWidth", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MaxWidth", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MinDepth", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MaxDepth", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MinArea", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MaxArea", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MinImperviousArea", type = Integer.class),
                @StoredProcedureParameter(mode = ParameterMode.IN, name = "MaxImperviousArea", type = Integer.class)
})
@Entity
public class ModelSearchByModelEntity implements Serializable{

//Properties with @Id, @Basic and @Column annotations, along with getters and setters
}

现在，我尝试使用Spring DATA JPA

public interface IModelSearchByModelRepository extends Repository<ModelSearchByModelEntity, String> {

    @Procedure(name = "ModelSearchByModel")
    List<ModelSearchByModelEntity> findByCriteria(@Param("RegionCode") String regionCode,
                                                  @Param("BuildingCode") String buildingCode,
                                                  @Param("ProductCode") String productCode,
                                                  @Param("StatusCode") String statusCode,
                                                  @Param("MinWidth") Integer minWidth,
                                                  @Param("MaxWidth") Integer maxWidth,
                                                  @Param("MinDepth") Integer minDepth,
                                                  @Param("MaxDepth") Integer maxDepth,
                                                  @Param("MinArea") Integer minArea,
                                                  @Param("MaxArea") Integer maxArea,
                                                  @Param("MinImperviousArea") Integer minImperviousArea,
                                                  @Param("MaxImperviousArea") Integer maxImperviousArea);
}

使用上面的代码，程序失败，“位置和命名参数混合无效”。

然后我试图忽略DATA JPA并尝试使用StoredProcedureQuery，如下所示

    StoredProcedureQuery storedProcedureQuery = entityManagerFactory.createEntityManager().createStoredProcedureQuery("ModelSearchByModel",ModelSearchByModelEntity.class);
    storedProcedureQuery.setParameter("RegionCode",regionCode);
    //all other parameter setters.. 


    return storedProcedureQuery.execute() ? storedProcedureQuery.getResultList() : null;

有了这个，我得到如下错误

Caused by: java.lang.IllegalArgumentException: Parameter with that name [ArchRegionCode] did not exist
    at org.hibernate.jpa.spi.BaseQueryImpl.findParameterRegistration(BaseQueryImpl.java:503) [hibernate-entitymanager-4.3.7.Final.jar:4.3.7.Final]

我不明白如何做到这一点。不确定是否有办法控制ParameterStrategy值。

这里有什么建议吗？

Answer 1

您必须在设置之前注册参数：

awk

Answer 2

如果要调用使用注释@NamedStoredProcedureQuery声明的存储过程，则应使用方法createNamedStoredProcedureQuery，而不是createStoredProcedureQuery。后者适用于您不想使用注释的情况，在这种情况下您必须手动注册参数。

因此，如果您想使用注释，您可以编写类似

的内容

entityManagerFactory.createEntityManager()
.createNamedStoredProcedureQuery("ModelSearchByModel", ModelSearchByModelEntity.class)
.setParameter("RegionCode",regionCode);

否则

StoredProcedureQuery storedProcedureQuery = entityManagerFactory.createEntityManager().createStoredProcedureQuery("SPR_ModelSearchByModel",ModelSearchByModelEntity.class);
storedProcedureQuery.registerStoredProcedureParameter("RegionCode", String.class , ParameterMode.IN);
// etc.
storedProcedureQuery.setParameter("RegionCode",regionCode);
// etc.

请注意，在第二个示例中，要使用的名称是存储过程的原始名称。

Hibernate存储过程调用多个命名参数并且结果集不起作用
