我有一个名为EmployeeDepartment的实体,如下所示

@IdClass(EmployeeDepartmentPK.class) //EmployeeDepartmentPK is a serializeable object
@Entity
EmployeeDepartment{

@Id
private String employeeID;

@Id
private String departmentCode;
---- Getters, Setters and other props/columns
}

我有一个Spring Data Repository,如下所示

@RepositoryRestResource(....)
public interface IEmployeeDepartmentRepository extends PagingAndSortingRepository<EmployeeDepartment, EmployeeDepartmentPK> {

}

此外,我有一个注册转换器从String转换为EmployeeDepartmentPK.

现在,对于一个由ID employeeID ="abc123"和departmentCode ="JBG"限定的实体,我希望在调用SDR接口时使用的ID是abc123_JBG.例如,http:// localhost/EmployeeDepartment/abc123_JBG应该获取结果,事实确实如此.

但是,当我尝试使用PUT保存实体时,Spring Data Commons的BasicPersistentEntity类中可用的ID属性的departmentCode值为abc123_JBG.这是错的.我不确定这是否是预期的行为.

请帮忙.

谢谢!

我使用spring数据rest进行分析。但是，当实体具有复合主键时，我不知道如何通过提供主键来获得实体。
