如何使用实体管理器在 spring 中调用 oracle 存储过程？

Question

create or replace PROCEDURE TEST  
(
Role IN VARCHAR2, 
     OUTPUT 
 OUT SYS_REFCURSOR
)
AS
BEGIN
 OPEN OUTPUT FOR   
Select PC.PRODUCT_NAME,P.PARTNER_NAME
............
.............
  WHERE PC.ROLE_NAME='POS_LEAD';
END TEST;

Calling above procedure In Spring using below code

StoredProcedureQuery findByYearProcedure = entityManager.createStoredProcedureQuery("TEST");

StoredProcedureQuery storedProcedure = findByYearProcedure
            .registerStoredProcedureParameter("Role", String.class, ParameterMode.IN)
            .registerStoredProcedureParameter("SYS_REFCURSOR", Object.class,ParameterMode.REF_CURSOR);
            .setParameter("Role", "admin");

System.out.println(storedProcedure.getResultList());

But I am getting an error.

 ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'TEST' ORA-06550: line 1, column 7: PL/SQL: Statement ignored

can any one help?

I tried to duplicate your issue but I cannot, though I'm using Postgres instead of Oracle. Just to be sure, can you do this instead:

StoredProcedureQuery storedProcedure = findByYearProcedure
            .registerStoredProcedureParameter(1, String.class, ParameterMode.IN)
            .registerStoredProcedureParameter(2, Object.class,ParameterMode.REF_CURSOR);
            .setParameter("Role", "admin");

Thanks
