Angular Post请求转为待处理状态且未命中服务器

Question

我试图使用发布请求获取电子邮件ID的用户列表，有时发布请求转为待处理状态，并永远保持相同状态。如果我重新启动tomcat，则该请求有效，但过了一段时间发生相同的问题。

  

下面是在angular中调用的post方法

loadBOEDetailsListByEmail(emailId, password) {
const url = `${environment.url}backofficeemployee/detailsByBoeEmailId/`;
const params = {
  resetEmail: emailId
};
const myHeader = new HttpHeaders();
myHeader.append('Content-Type', 'application/x-www-form-urlencoded');
return Observable.create(observer => {
  this.http.post(url, params, { headers: myHeader }).subscribe(
    (response: any) => {
      if (response && response.data && response.data[0] !== undefined) {
        this.accountList = response.data;
        const boe = response.data[0];
        this.checkAccountValidity(boe, password, observer);
      } else {
        observer.error('No account found');
      }
    },
    () => observer.error('Employee service call failed')
  );
});

}

  

在Java方面，这就是我的接收方式

    // Backoffice employee - Details by BoeUserId
@PostMapping(value = "/detailsByBoeEmailId/")
    public @ResponseBody Map<String, Object> getBackofficeemployeeDetailsByBoeEmailId(@RequestBody ResetpasswordRequestDto requestDto) {
        log.info(" boeEmailId in getBackofficeemployeeDetails {}", requestDto.getResetEmail());
        try {
            List<BackofficeemployeeResponseDto> backofficeemployeeResponseDto = backofficeemployeeService
                    .getByBoeEmailId(requestDto.getResetEmail());
            return JsonUtils.mapOK(backofficeemployeeResponseDto);
        } catch (Exception e) {
            log.error("Exception in getBackofficeemployeeDetailsByBoeEmailId", e);
            return JsonUtils.mapError(ERROR_MSG + e.getMessage());
        }
    }
