Question

我正在尝试使用JPA 2.1（Hibernate 4.3.5）调用数据库存储过程（Oracle 10g）。该过程在输出光标中返回结果：

PROCEDURE GET_EMPLOYEE(
  P_ID_EMP  IN       VARCHAR2,
  P_CURSOR   OUT   TYPES.cursor_type
)
AS ...

Java代码：

@NamedStoredProcedureQuery(name = "Employee.findById", 
    resultClasses = Employee.class, 
    procedureName = "GET_EMPLOYEE", 
    parameters = {
        @StoredProcedureParameter(mode = ParameterMode.IN, name = "P_ID_EMP", type = String.class),
        @StoredProcedureParameter(mode = ParameterMode.REF_CURSOR, name = "P_CURSOR", type = void.class) 
    }
)

呼叫：

StoredProcedureQuery query = em.createNamedStoredProcedureQuery("Employee.findById");
query.setParameter("P_ID_EMP", "ID00001");
List<Employee> employees = query.getResultList(); //exception launched here

此异常已启动：

Exception in thread "main" java.lang.UnsupportedOperationException: org.hibernate.dialect.Oracle10gDialect does not support resultsets via stored procedures
    at org.hibernate.dialect.Dialect.registerResultSetOutParameter(Dialect.java:1612)
    at org.hibernate.engine.jdbc.cursor.internal.StandardRefCursorSupport.registerRefCursorParameter(StandardRefCursorSupport.java:94)
    at org.hibernate.procedure.internal.AbstractParameterRegistrationImpl.prepare(AbstractParameterRegistrationImpl.java:298)
    at org.hibernate.procedure.internal.ProcedureCallImpl.buildOutputs(ProcedureCallImpl.java:417)

    at org.hibernate.jpa.internal.StoredProcedureQueryImpl.outputs(StoredProcedureQueryImpl.java:251)
    at org.hibernate.jpa.internal.StoredProcedureQueryImpl.getResultList(StoredProcedureQueryImpl.java:334)

使用Eclipselink 2.5.1（但不能使用它），相同的代码效果很好。

我知道我可以从entitymanager获取JDBC连接并使用经典的Resultset内容来检索结果，但我想使用JPA 2.1 - Hibernate。

谢谢。

org.hibernate.dialect.Oracle10gDialect不支持通过存储过程的结果集
