Spring Rest API - multiple threads -

-

i have developed spring rest api takes multipart file in request , uploading them aws s3 location. process taking time , client has wait whole process completed.

i not want client wait upload process complete want send image urls in response.

can send image urls in response , open thread uploading images s3?

you can achieve via springs' deferredresult leverages servlet 3.0 async capabilities.

your controller below (originally posted here tomasz)

@requestmapping("/upload") @responsebody public deferredresult<string> upload() {     final deferredresult<string> deferredresult = new deferredresult<>();     runinotherthread(deferredresult);     return deferredresult; }  private void runinotherthread(deferredresult<string> deferredresult) {     // call aws s3 upload , collect response     deferredresult.setresult("file uploaded"); }

refer tutorial complete working example.

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
