通过查询存储库中获取自定义对象的列表JPA

我想有EmployeeTimesheetDTO

public class EmployeeTimesheetDTO { 
    private String name; 
    private String employeeId; 
    private String filename; 
}

的列表通过函数参数给出的时期。但是，这是很重要的员工列表必须始终显示的事件时间表不存在的雇员（在列表为空值）

@Query("SELECT new package.domain.EmployeeTimesheetDTO(em.employeeID as employeeId, em.name as name, tse.filename as filename)" + 
     " FROM EmployeeEntity em LEFT JOIN TimesheetEntity tse ON em.employeeID=tse.id.ownerId WHERE tse.id.period =:period") 
List<EmployeeTimesheetDTO> findAllEmployeeTimesheet(@Param("period") String period);

我收到的错误：

Validation failed for query for method public abstract java.util.List

错误，而我尝试运行出现我的程序;

更换WHERE到AND，如果TimesheetEntity标准出现在WHERE，那么它就像INNER JOIN：

@Query("SELECT new package.domain.EmployeeTimesheetDTO(em.employeeID as employeeId, em.name as name, tse.filename as filename)" + 
     " FROM EmployeeEntity em LEFT JOIN TimesheetEntity tse ON em.employeeID=tse.id.ownerId AND tse.id.period =:period") 
List<EmployeeTimesheetDTO> findAllEmployeeTimesheet(@Param("period") String period);

好，但这不是解决与错误验证mahor问题失败的查询方法公共抽象java.util.List – VANILKA
