具有多个命名参数和结果集的 Hibernate 存储过程调用不起作用

Question

我有一个存储过程，它接受输入列表，然后输出结果集。使用的 DB 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);
}

使用上述代码，程序失败并显示“位置参数和命名参数的混合无效”。

然后我尝试忽略 DATA JPA 并尝试使用如下所示的 StoredProcedureQuery

    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？

在设置参数之前必须先注册参数：

StoredProcedureQuery storedProcedureQuery = entityManagerFactory.createEntityManager().createStoredProcedureQuery("ModelSearchByModel",ModelSearchByModelEntity.class);

storedProcedureQuery.registerStoredProcedureParameter("RegionCode", String.class , ParameterMode.IN);
// register all the other parameters...

storedProcedureQuery.setParameter("RegionCode", regionCode);
// set all the other parameters...

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