无法将类型 'java.lang.String' 的值转换为所需类型 'java.time.LocalDate'

Question

我有 web-rest Spring 应用程序。对于第二个实体，我有 2 个带有 LocalDate 的字段：arrivalTime、departmentTime。我实现了 CRUD 方法。没关系。但是当我尝试按日期搜索时（从到达时间到出发时间）我有一个错误：

Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.time.LocalDate';

我的休息模块答案正确。我不知道该怎么办。我的实体：

   @NotNull(message = "arrival time is a required field")
@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
@DateTimeFormat(pattern = "yyyy-MM-dd")
private LocalDate arrivalTime;

@NotNull(message = "departure time is a required field")
@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
@DateTimeFormat(pattern = "yyyy-MM-dd")
private LocalDate departureTime;

public Resident() {
}

public Resident(String firstName, String lastName, String email, LocalDate arrivalTime, LocalDate departureTime, Integer apartmentNumber) {
    this.firstName = firstName;
    this.lastName = lastName;
    this.email = email;
    this.arrivalTime = arrivalTime;
    this.departureTime = departureTime;
    this.apartmentNumber = apartmentNumber;
}

我的网络控制器

    @GetMapping("/search")
public String searchAllResidentByDate(@RequestParam(name = "arrivalTime", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate arrivalTime,
                                      @RequestParam(name = "departureTime", required = false) @DateTimeFormat(iso = DateTimeFormat.ISO.DATE) LocalDate departureTime,
                                      Model model) {
    LOGGER.debug("search residents by date() {} {}", arrivalTime, departureTime);
    List<Resident> residentListByTime = residentService.findAllByTime(arrivalTime, departureTime);
    model.addAttribute("allResidentsAttribute", residentListByTime);
    return "Residents_list";
}

服务休息：

    @Override
public List<Resident> findAllByTime(LocalDate arrivalTime, LocalDate departureTime) {
    String searchUrl = "http://localhost:8080/search";
    String arrivalTimeString = "{arrivalTime}";
    String departureTimeString = "{departureTime}";
    UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(searchUrl).queryParam("arrivalTime", arrivalTimeString)
            .queryParam("departureTime", departureTimeString);
    HttpHeaders headers = new HttpHeaders();
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    HttpEntity<Apartment> entity = new HttpEntity<>(headers);
    return restTemplate.exchange(builder.build().toUri(), HttpMethod.GET, entity, new ParameterizedTypeReference<List<Resident>>() {
    }).getBody();
}

休息控制器：

    @GetMapping("/search")
public ResponseEntity<List<Resident>> searchAllResidentByDate(
        @RequestParam("arrivalTime") @DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate arrivalTime,
        @RequestParam("departureTime") @DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate departureTime) {
    List<Resident> residents = residentService.findAllByTime(arrivalTime, departureTime);
    LOGGER.debug("Find residents by date, where arrivalTime = {} and end departureTime => {} In the amount of {} ", arrivalTime, departureTime, residents.size());
    return new ResponseEntity<>(residents, HttpStatus.FOUND);
}

通过这个 URL:

我得到了正确的休息结果

http://localhost:8090/search?arrivalTime=2021-03-01&departureTime=2021-04-04

Html部分：

    <form class="d-flex"
      action="/search"
      th:method="@{get}">
    <div class="col-sm-2">
        <input class="form-control form-control-sm" name="arrivalTime" type="date" aria-label="arrivalTime"
               id="arrivalTime">
    </div>
    <div class="col-sm-2">
        <input class="form-control form-control-sm" name="departureTime" type="date" aria-label="departureTime"
               id="departureTime">
    </div>
    <button type="submit" class="btn btn-outline-secondary btn-sm">Search</button>
</form>

当我点击搜索按钮时，我有这个 URL:

http://localhost:8080/search?arrivalTime=2021-03-01&departureTime=2021-05-09 I need this pattern:yyyy-MM-dd. But something doesn't work.

我使用了错误的端口。我需要 8090，而不是 8080。谢谢
