难道是Spring 的BUG？很诡异的问题。求解答

@Controller

@RequestMapping("/attendance/attendanceCheckIn.do")

public class AttendanceCheckInController

{

		

	private final AttendanceCheckInService attendanceCheckInService;

	private final AttendanceCustomParaService attendanceCustomParaService;

	private final OverTimeReportService overTimeReportService;

	private final AttendancePersonSchedulingService personSchedulingService;

	private final AttendanceSpecialWorkSystemService specialWorkSystemService;

	

	@Autowired

	public AttendanceCheckInController(AttendanceCheckInService attendanceCheckInService,

			AttendanceCustomParaService attendanceCustomParaService

			,OverTimeReportService overTimeReportService,

			AttendancePersonSchedulingService personSchedulingService,

			AttendanceSpecialWorkSystemService specialWorkSystemService)

	{

		super();

		this.attendanceCheckInService = attendanceCheckInService;

		this.attendanceCustomParaService = attendanceCustomParaService;

		this.overTimeReportService = overTimeReportService;

		this.personSchedulingService=personSchedulingService;

		this.specialWorkSystemService=specialWorkSystemService;

	}

	

	

	

	//跳转到签到界面

	@RequestMapping(params = "method=checkIn", method = RequestMethod.GET)

	public String setupForm(HttpServletRequest request, Model model,HttpSession session,HttpServletResponse response)

			throws Exception

	{

		

		

		System.out.println("=====================================");



		

		return "/attendance/attendanceCheckIn";

	}

}
