按日期搜索 Web 方法的问题使用 GetMapping

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（从到达时间到出发时间）搜索时，没有任何反应。刚刚在浏览器中加载。

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(pattern = "yyyy-MM-dd") LocalDate arrivalTime,
                                      @RequestParam(name = "departureTime", required = false) @DateTimeFormat(pattern = "yyyy-MM-dd") 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 arrivalTimeString = arrivalTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
    String departureTimeString = departureTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
    String searchUrl = "http://localhost:8080/search?arrivalTime=" + arrivalTimeString + "&departureTime=" + departureTimeString;

    HttpHeaders headers = new HttpHeaders();
    headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
    HttpEntity<Apartment> entity = new HttpEntity<>(headers);
    return restTemplate.exchange(searchUrl, HttpMethod.GET, entity, new ParameterizedTypeReference<List<Resident>>() {
    }).getBody();
}

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>

Answer 1

您的 REST 服务尝试向 MVC 端点请求 returns HTML 字符串，而不是居民列表。在 CRUD 中实现 findAllByTime，而不是 REST 请求。

Answer 2

您可能有兴趣使用这个库：https://github.com/turkraft/spring-filter

它将让您运行搜索查询，例如：

/search?filter= average(ratings) > 4.5 and brand.name in ('audi', 'land rover') and (year > 2018 or km < 50000) and color : 'white' and accidents is empty

它支持枚举、日期和集合等多种字段类型。

Answer 3

谢谢，我发现了一个错误。我需要使用 8090 端口而不是 8080。
