Question

我使用Java API，并获得GET调用的HTTP状态400。展示了该API，

@GetMapping("/findWithRange")
public ResponseEntity<List<Appointment>> findAllWithCreationRange(@RequestParam("start") Date start, @RequestParam("end") Date end) {

    List<Appointment> appointments = service.findAllWithCreationRange(start, end);

    if (Objects.isNull(appointments)) {
        ResponseEntity.badRequest().build();
    }

    return ResponseEntity.ok(appointments);
}

我拨打了cURL GET呼叫

$ curl -X GET http://localhost:8080/api/v1/appointments/findWithRange?start=2018-10-01&end=2018-10-15

我得到答复，

{"timestamp":"2019-02-10T07:58:22.151+0000","status":400,"error":"Bad Request","message":"Required Date parameter 'end' is not present","path":"/api/v1/appointments/findWithRange"}

这表明end参数未出现在调用中，这似乎是不正确的。还提供了存储库和服务类，

@Repository
public interface AppointmentRepository extends CrudRepository<Appointment, Long> {

@Query(value = "SELECT * FROM Appointment WHERE appointment_date <= :creationDateTime", nativeQuery = true)
List<Appointment> findAllWithCreationDateTimeBefore(@Param("creationDateTime") Date creationDateTime);


@Query(value = "SELECT * FROM Appointment WHERE appointment_date >= :startDate AND appointment_date <= :endDate", nativeQuery = true)
List<Appointment> findAllWithCreationRange(@Param("startDate") Date startDate, @Param("endDate") Date endDate);
}

服务类

@Service
public class AppointmentService {
@Autowired
private AppointmentRepository repository;

public Optional<Appointment> findById(Long id) {
    return repository.findById(id);
}

public List<Appointment> findAll() {
    return (List<Appointment>) repository.findAll();
}

public List<Appointment> findAllWithCreationDateTimeBefore(Date date) {
    return (List<Appointment>) repository.findAllWithCreationDateTimeBefore(date);
}

public List<Appointment> findAllWithCreationRange(Date start, Date end) {
    return (List<Appointment>) repository.findAllWithCreationRange(start, end);
}

public Appointment save(Appointment appointment) {
    return repository.save(appointment);
}

public void deleteById(Long id) {
    repository.deleteById(id);
}

public void deleteAll() {
    repository.deleteAll();
}
}

我也尝试用&&进行呼叫

$ curl -X GET http://localhost:8080/api/v1/appointments/findWithRange?start=2018-10-01&&end=2018-10-15

，这将返回相同的响应并且没有帮助。我在这里想念什么并且可以正常运行吗？

注意：我有一个类似的端点，可以正常工作，这使我更加好奇。

// curl -X GET http://localhost:8080/api/v1/appointments/creationDateTime?start=2018-10-01 | jq

    @GetMapping("/creationDateTime")
    public ResponseEntity<List<Appointment>> findAllWithCreationDateTimeBefore(@RequestParam("start") Date date) {

        List<Appointment> appointment = service.findAllWithCreationDateTimeBefore(date);

        if (Objects.isNull(appointment)) {
            ResponseEntity.badRequest().build();
        }

        return ResponseEntity.ok(appointment);
    }

基本上，您不是在提供DateFormat，否则不能将String转换为日期。

像这样使用@DateTimeFormat("yyyy-MM-dd")

@GetMapping("/findWithRange")
public ResponseEntity<List<Appointment>> findAllWithCreationRange(@RequestParam("start") @DateTimeFormat("yyyy-MM-dd") Date start, @RequestParam("end") @DateTimeFormat("yyyy-MM-dd") Date end) {

    List<Appointment> appointments = service.findAllWithCreationRange(start, end);

    if (Objects.isNull(appointments)) {
        ResponseEntity.badRequest().build();
    }

    return ResponseEntity.ok(appointments);
}

“状态”：400，“错误”：“错误的请求”，“消息”：“必需的日期参数'end'不存在”
