java 调用Oracle 存储过程（SpringBoot下的事务管理）

1.在事务的实体类里添加getSession方法

@Repository("dao3")
public class OracleRepositoryImpl extends NaviRepositoryImpl {
/** 实体类管理类对象 */
@PersistenceContext(unitName = "thirdaryPersistenceUnit")
private EntityManager entityManager;

@Override
public EntityManager getEntityManager() {
return entityManager;
}

//getSession
public Session getEntityManagerSession() {
HibernateEntityManager hEntityManager = (HibernateEntityManager)entityManager;
Session session = hEntityManager.getSession();
return session;
}
}

2.实现调用无返回值的存储过程

Session session = dao3.getEntityManagerSession();
try {
countSize=callProcedure(session);
} catch (Exception e) {
//todo test rollback
}

private void callProcedure(Session session) {

// call proc
SQLQuery queryLoadProduct = session.createSQLQuery("{call ARRAY_BASE_LOADER.LOAD_PRODUCT()}");
queryLoadProduct.executeUpdate();
}

3.实现调用有返回值的存储过程
 CallableStatement statement = cp.getConnection().prepareCall(   
                "{call MachineDataQuery(?,?,?,?,?,?,?,?,?,?,?,?,?,?)}"); 
    statement.setInt(1, machineId);
    statement.setInt(2, jobId);
    statement.setInt(3, partTypeId);
    statement.setInt(4, compentId);
