我正在尝试使用休眠的实体管理器从db2数据库中调用存储过程,并将结果作为对象返回。我正在使用@NamedStoredProcedureQuery批注,它似乎没有被休眠找到。我收到错误消息:“找不到具有该名称的@NamedStoredProcedureQuery:Create_Division”。任何想法都很棒。
豆子:

<property name="dataSource" ref="dataSource" />
<property name="persistenceUnitName" value="demoJPAUnit" />

查询输出对象:
@NamedStoredProcedureQuery(
name="Create_Division",
procedureName="MD.PMDBD017",
resultClasses = {CreateDivisionResult.class},
parameters={
@StoredProcedureParameter(name="IN_ENTY",mode=ParameterMode.IN,type=Integer.class),
@StoredProcedureParameter(name="IN_PARNT_ENTY",mode=ParameterMode.IN,type=Integer.class),
@StoredProcedureParameter(name="IN_ACTION",mode=ParameterMode.IN,type=String.class),
@StoredProcedureParameter(name="IN_ENTY_XREF",mode=ParameterMode.IN,type=String.class),
@StoredProcedureParameter(name="OUT_ENTY",mode=ParameterMode.OUT,type=Integer.class),
@StoredProcedureParameter(name="OUT_ID",mode=ParameterMode.OUT,type=String.class),
@StoredProcedureParameter(name="OUT_ENTY_XREF",mode=ParameterMode.OUT,type=String.class),
@StoredProcedureParameter(name="OUT_SQLCODE",mode=ParameterMode.OUT,type=Integer.class),
@StoredProcedureParameter(name="OUT_STATUS",mode=ParameterMode.OUT,type=String.class),
@StoredProcedureParameter(name="OUT_ERRORTEXT",mode=ParameterMode.OUT,type=String.class),
}
)
public class CreateDivisionResult implements Serializable {
@Id
public String OUT_ENTY;
public String OUT_ID;
public String OUT_ENTY_XREF;
public String OUT_SQLCODE;
public String OUT_STATUS;
public String OUT_ERRORTEXT;
}
DAO代码:
StoredProcedureQuery query = manager.createNamedStoredProcedureQuery("Create_Division");
query.setParameter("IN_ENTY", 111);
query.setParameter("IN_PARNT_ENTY", 11111);
query.setParameter("IN_ACTION", "CREATE");
query.setParameter("IN_ENTY_XREF", "ED");
List<CreateDivisionResult> results = query.getResultList();
编辑:
因此,我添加了@Entity并确实解决了原始错误,但是输出参数仍未映射到CreateDivisionResult对象。我只能使用query.getOutputParameterValue获取每个单独的字段。这仅仅是对JPA的限制吗?
最佳答案
@NamedStoredProcedureQuery应该应用于Entity类或映射类
似乎您的'CreateDivisionResult'中缺少@Entity
