Question

当我尝试使用Spring RestApi测试我的“testCreateUser”方法时出现错误，uploadNewUser.xml包含有关用户和角色的登录信息。

  @Test
  public void testCreateUser() throws Exception {
    Reader reader = getFileReader("src/test/resources/uploadNewUser.xml");
    String input_xml = IOUtils.toString(reader);

    byte[] content = input_xml.getBytes();
    request.addHeader("Accept", "application/xml");
    request.addHeader("Content-Type", "application/xml");
    request.setContent(content);
    request.setContentType("text/xml");
    request.setMethod(RequestMethod.POST.name());
    request.setRequestURI("/restapi/users/");
    final ModelAndView mav = handle(request, response);
    Map<String, Object> map = mav.getModel();
    for (Entry<String, Object> entry : map.entrySet()) {
      String key = entry.getKey();
      UserCollection collection = (UserCollection) entry.getValue();

org.springframework.validation.BindingResult.error = com.xxx.dashboard.restapi.GlobalResponse@42a4fd6d

错误堆栈：

java.lang.ClassCastException: com.xxx.dashboard.restapi.GlobalResponse cannot be cast to com.xxx.dashboard.restapi.UserCollection

我遇到的问题是无法将GlobalRespose转换为UserCollection。任何人都可以告诉我我在做什么是错的？提前感谢任何帮助或指示

 @Controller("userrestapi")
    @RequestMapping(value = { "/restapi/users/", "/restapi/users" })
    public class UserRestApi extends AbstractBaseApi {
...
         @RequestMapping(method = RequestMethod.POST)
          @ResponseStatus(value = HttpStatus.CREATED)
          public ModelAndView createNewUser(@RequestBody UserCollection userCollection,
              @RequestHeader(value = "accept", required = false) String accept,
              @RequestHeader(value = "version", required = false) String version) {
            try {
              OOUser ooUser = userCollection.getUsers().get(0);
              Mapper mapper = (Mapper) userVersions.get(Constants.USER_DETAIL_VERSION_MAPPER_KEY);
              int userId = usersRestApiService.validateAndCreateNewUser(ooUser, mapper);
              List<FilterField> filterFieldList = new ArrayList<FilterField>();
              filterFieldList.add(new FilterField("userId", String.valueOf(userId)));
              return getUserDetailsForFilter(filterFieldList, accept, version, mapper);
            } catch (Exception ex) {
              logger.warn("Api exception", ex);
              return getModelAndView(accept, "error", getGlobalResponse(ex));
            }

abstractbaseapi包含以下

public class AbstractBaseApi {

  public static final String XML_VIEW = "apiXmlView";
  public static final String JSON_VIEW = "apiJsonView";
  public static final String JSON_ACCEPT_HEADER = "application/json";
  public static final String JSON_CONTENT_HEADER = "Content-type: application/json";
  public static final String XML_CONTENT_HEADER = "Content-type: text/html;charset=utf-8";
  public static final int MAX_COUNT = 100;
  public static final String XML_REQUEST_ERROR_FORMAT = "<?xml version='1.0' encoding='UTF-8'?><GlobalResponse xmlns='http://www.operative.com/api' xmlns:v2='http://www.operative.com/api/v2' xmlns:v1='http://www.operative.com/api/v1'> <error errorCode='%1$s' text='%2$s'/> </GlobalResponse>";
  public static final String JSON_REQUEST_ERROR_FORMAT = "{error:{errorCode:'%1$s',text:'%2$s'}}";

  protected final Logger logger = Logger.getLogger(this.getClass());

  protected ModelAndView getModelAndView(String accept, String key, Object value) {
    String view = XML_VIEW;

    if (accept != null && accept.toLowerCase().contains(JSON_ACCEPT_HEADER)) {
      view = JSON_VIEW;
    }
    if (logger.isDebugEnabled()) {
      logger.debug("Accept Header:" + accept + " , generating:" + view);
    }

    return new ModelAndView(view, BindingResult.MODEL_KEY_PREFIX + key, value);
  }

您的模型包含的内容超出您的想象。

您正在浏览模型并查找您的用户集合。但是，地图中第一个遇到的对象似乎是GlobalResponse地图。

您可能只是从模型中获取名称，即

UserCollection collection = (UserCollection) mav.getModel().get("userCollection");

而不是迭代..
