Question

项目。

示例：

我的oracle过程在另一个游标中返回一个游标：

CREATE OR REPLACE PROCEDURE get_emp (p_name IN VARCHAR2,p_recordset OUT SYS_REFCURSOR) AS 
BEGIN 
     OPEN p_recordset FOR
          select
               employee_id,
               name,
               office,
               proc_get_company(company_id) as company
           from
               table_employee
           where
               name like '%' || :p_name || '%'
END;

程序查找公司

CREATE OR REPLACE PROCEDURE proc_get_company (company_id IN NUMBER,p_recordset OUT SYS_REFCURSOR) AS 
BEGIN
   OPEN p_recordset FOR
      select
           company_id,
           company_name
      from
           table_company
      where
           company_id = :company_id
END;

我的员工班级

@NamedStoredProcedureQuery(name = "getEmployee",procedureName = "get_emp",parameters = { 
     @StoredProcedureParameter(mode = ParameterMode.IN,type = String.class, name = "p_name"), 
     @StoredProcedureParameter(mode = ParameterMode.REF_CURSOR,type = void.class, name = "p_recordset")
})
@Entity
public class Employee {

   @Column(name = "employee_id") 
   private long employeeId;

   @Column(name = "name")
   private String name;

   @Column(name = "office")
   private String office;

   private Company company; 

   ...
}

我的公司课程

@Entity
public class Company {

   @Column(name = "company_id") 
   private long  companyId;

   @Column(name = "company_name")
   private String name;   
   ...
}

Spring存储库

@Repository
public interface EmployeeDAO extends CrudRepository<Employee, Long>{

   @Procedure(name = "getEmployee",outputParameterName="p_recordset")
   public List<Employee> findEmployeeByName(@Param("p_name") String name)

}

问题：

如何使用批注将光标（ proc_get_company（company_id）作为公司）映射到另一个具有“ NamedStoredProcedureQuery”，Spring数据和eclipseLink的“选择光标”（p_recordset）中？

注意： 它可以使用“选择”的其他字段，但是其上的光标（proc_get_company（company_id））不会通过注释返回。：（

你能帮我吗？

带有eclipseLink的@NamedStoredProcedureQuery中的ref_cursor
