I have the following in my controller, in a Spring-Boot application:
@RequestMapping(method=RequestMethod.GET,value="/info")
public DataModel getinfodata()
{
//this method runs some script which takes more than 3 minutes and sends the response back
return run_xyz()
}
In my angular app, I have this:
export class FetchService {
private _url:string="/info";
constructor(private _http:Http) { }
getData():any
{
return this._http.get(this._url).map((res:Response)=>res.json()).
catch(this.errorHandler).subscribe(data=>console.log(data));
}
errorHandler(error: Response){
console.error(error);
return Observable.throw(error || "Server Error");
}
The issue I am facing currently is that the Http get
is making silent retries to the server, and as result, my expensive script is getting called 3 or 4 times. Is there an approach by which the get
will make only a single request with 0 retries and wait until the script is completed and then the response should be sent back.I am calling the getData method only once.
