import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*; import java.util.List; @RestController @RequestMapping("/transportation") public class TransportationController<TransportationRepository> { @Autowired private TransportationRepository transportationRepository; @PostMapping("/create") public ResponseEntity<?> createTransportation(@RequestBody TransportationDto transportationDto) { Transportation transportation = new Transportation(); transportation.setFrom(transportationDto.getFrom()); transportation.setTo(transportationDto.getTo()); transportation.setDepartureTime(transportationDto.getDepartureTime()); transportation.setArrivalTime(transportationDto.getArrivalTime()); transportationRepository.save(transportation); return ResponseEntity.ok("Transportation created successfully"); } @GetMapping("/all") public ResponseEntity<?> getAllTransportations() { List<Transportation> transportations = transportationRepository.findAll(); return ResponseEntity.ok(transportations); } @GetMapping("/{id}") public ResponseEntity<?> getTransportationById(@PathVariable Long id) { Transportation transportation = transportationRepository.findById(id).orElse(null); if (transportation == null) { return ResponseEntity.notFound().build(); } return ResponseEntity.ok(transportation); } }这段代码中所有transportationDto的方法报错，比如Cannot resolve method 'getFrom' in 'TransportationDto'，请帮我修改

根据报错信息来看，TransportationDto中缺少getFrom等方法，所以需要在TransportationDto中添加相应的getter方法，例如：

public class TransportationDto {
    private String from;
    private String to;
    private LocalDateTime departureTime;
    private LocalDateTime arrivalTime;

    public String getFrom() {
        return from;
    }

    public void setFrom(String from) {
        this.from = from;
    }

    public String getTo() {
        return to;
    }

    public void setTo(String to) {
        this.to = to;
    }

    public LocalDateTime getDepartureTime() {
        return departureTime;
    }

    public void setDepartureTime(LocalDateTime departureTime) {
        this.departureTime = departureTime;
    }

    public LocalDateTime getArrivalTime() {
        return arrivalTime;
    }

    public void setArrivalTime(LocalDateTime arrivalTime) {
        this.arrivalTime = arrivalTime;
    }
}

同时，TransportationController中依赖的TransportationRepository需要声明泛型类型，例如：

@RestController
@RequestMapping("/transportation")
public class TransportationController {
    @Autowired
    private TransportationRepository transportationRepository;

    @PostMapping("/create")
    public ResponseEntity<?> createTransportation(@RequestBody TransportationDto transportationDto) {
        Transportation transportation = new Transportation();
        transportation.setFrom(transportationDto.getFrom());
        transportation.setTo(transportationDto.getTo());
        transportation.setDepartureTime(transportationDto.getDepartureTime());
        transportation.setArrivalTime(transportationDto.getArrivalTime());
        transportationRepository.save(transportation);
        return ResponseEntity.ok("Transportation created successfully");
    }

    @GetMapping("/all")
    public ResponseEntity<?> getAllTransportations() {
        List<Transportation> transportations = transportationRepository.findAll();
        return ResponseEntity.ok(transportations);
    }

    @GetMapping("/{id}")
    public ResponseEntity<?> getTransportationById(@PathVariable Long id) {
        Transportation transportation = transportationRepository.findById(id).orElse(null);
        if (transportation == null) {
            return ResponseEntity.notFound().build();
        }
        return ResponseEntity.ok(transportation);
    }
}

希望这能够帮助到你。
