Spring Boot-正文的TestRestTemplate LocalDate null

Question

当我从外部访问该服务时，可以很好地解析LocalDate类型的两个字段，并且该服务可以正常工作。

但是当我尝试使用TestRestTemplate测试非常相同的端点时，字段以null的形式到达控制器。 有什么问题吗？

更新： 这个问题更严重。当我尝试测试另一项服务时，我发现由TestRestTemplate完成的反序列化使得将LocalDate的列表构建为空列表。 我尝试使用自定义序列化器和反序列化器，但没有任何效果。 = /

控制器

@RestController
public class ReservationController {


@PostMapping("/reservation")
public String makeReservation(@RequestBody Reservation Reservation) {
    return this.reservationService.makeReservation(Reservation);
}
}

测试

@RunWith(SpringRunner.class)
@SpringBootTest(classes = AppRunner.class, webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class ReservationControllerTest {

@LocalServerPort
private int port;

private TestRestTemplate restTemplate = new TestRestTemplate();


@Test
public void attemp4(){
    LocalDate from = LocalDate.of(2019,1, 1);
    LocalDate to = LocalDate.of(2019,1, 21);

    Reservation Reservation = new Reservation(from, to);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    HttpEntity<Reservation> entity = new HttpEntity<>(Reservation, headers);

    String uri = "http://localhost:"+port+"/reservation";
    ResponseEntity<String> response = restTemplate.postForEntity(uri, entity, String.class);
    Assert.assertNotNull(response);
}

}

预订/ API DTO

public class Reservation {

private LocalDate checkIn;
private LocalDate checkOut;

public Reservation(LocalDate checkin, LocalDate checkout) {
    this.checkIn = checkin;
    this.checkOut = checkout;
}


public LocalDate getCheckIn() {
    return checkIn;
}

public LocalDate getCheckOut() {
    return checkOut;
}

}
