Angular 角度8大超时

我的Angular 8应用程序面临超时问题。我的应用程序需要向java后端服务器发送POST查询，该服务器将处理脚本7-8分钟。java应用程序将继续处理，但由于超时，我将无法读取响应。我在该链接中尝试了建议的解决方案，并能够减少超时。不幸的是，当我设置了较大的超时值时（900000），我在4分钟后遇到超时问题。当我用Postman测试POST查询时，我没有遇到这个问题

这是HttpInterceptor

import { Inject, Injectable, InjectionToken } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';
import { timeout } from 'rxjs/operators';

export const DEFAULT_TIMEOUT = new InjectionToken<number>('defaultTimeout');

@Injectable()
export class TimeoutInterceptor implements HttpInterceptor {
  constructor(@Inject(DEFAULT_TIMEOUT) protected defaultTimeout: number) {
  }

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    return next.handle(req).pipe(timeout(900000));
  }
}

我的服务

  import(docType:any,docContent:any){
    let params =  new HttpParams();
    params = params.append('docType', docType);
    params = params.append('docContent', docContent);
    return this.http.post<any>(`${BASE_PATH}/repriseManager/importAgreements`,{docType,docContent});
  }

导入（docType:any，docContent:any）{ 设params=newhttpparams（）； params=params.append（'docType'，docType）； params=params.append（'docContent'，docContent）； 返回此.http.post（`${BASE_PATH}/represemanager/importAgreements`，{docType，docContent}）； } 控制台日志
