我正在使用 JPA 调用 oracle 存储过程并得到下面提到的异常

错误

[4/24/14 9:07:37:583 EDT] 00000031 SystemOut O [EL Warning]: 2014-04-24 09:07:37.452--UnitOfWork(1697919964)--Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.4.0.v20120608-r11652): org.eclipse.persistence.exceptions.DatabaseException

代码 ：

    尝试{
                查询查询 = getEntityManager().createNamedQuery("refreshCategoryGuarantee");
                query.setParameter("SHIP_CODE", ship_code);
                query.setParameter("SAIL_DATE", DateUtil.getSqlDate(sailDate));
                return (Integer) query.getSingleResult();
            }catch（异常前）{
                System.out.println("************************************************ ******************************************");
                logger.error("使用参数执行 refreshCategoryGuarantee 命名查询时出错["+ship_code+","+sailDate+"] ", ex);
                返回 StoredProcedureConstants.RETURN_CODE_EXCEPTION;
           }
    
Here, refreshCategoryGuarantee is named query of STP_REFRESH_CATEGORY_GUARANTEE procedures.

-------------
<pre>
@NamedStoredProcedureQuery(  
        name="refreshCategoryGuarantee",  
        procedureName="STP_REFRESH_CATEGORY_GUARANTEE",  
        returnsResultSet=false,  
        parameters={  
            @StoredProcedureParameter(queryParameter="SHIP_CODE", type=String.class),  
            @StoredProcedureParameter(queryParameter="SAIL_DATE", type=Date.class),  
            @StoredProcedureParameter(queryParameter="return_code", direction=Direction.OUT, type=Integer.class) 
        })

我的问题是，当我在 oracle 中执行下面提到的匿名块时，它的工作没有任何问题

    设置服务器输出打开
    宣布
      rc 号码；
    开始
      STP_REFRESH_CATEGORY_GUARANTEE('OA','24-jan-15',rc);
      dbms_output.put_line('响应码：'||rc);
    结尾;

我不知道为什么我在 JPA 电话中得到这个？你能请人帮我解决吗？

StoredProcedureParameter定义中参数SAIL_DATE的类型，是java.util.date吗？它必须是 java.sql.date...

@StoredProcedureParameter(queryParameter="SAIL_DATE", type=java.slq.Date.class)

它与访问参数有关。不是参数名称。

1 - 访问 EntityManager。例如，通过 @PersistenceContext 私有 EntityManager em;

2 - 使用数字访问参数。这只是一个例子。

StoredProcedureQuery query = entityManager
.createStoredProcedureQuery("count_comments")
.registerStoredProcedureParameter(
    1,Long.class, ParameterMode.IN
)
.registerStoredProcedureParameter(
    2,Long.class, ParameterMode.OUT
)
.setParameter(1, 1L);
query.execute();
Long commentCount = (Long) query.getOutputParameterValue(2);
