Spring RestController 6 parallel execution? [duplicate]

Answer 1

In the log i can see instant:

PRE!!!!!!!!!!!!!

after approximately 15 sek. the next 5: PRE!!!!!!!!!!!!! PRE!!!!!!!!!!!!! PRE!!!!!!!!!!!!! PRE!!!!!!!!!!!!! PRE!!!!!!!!!!!!!

I think this is a problem / limitation from the browser.

When a request arrives to the servlet container (Tomcat for an example), a thread is retrieved from the pool to serve it. This means that the each request has it's own thread and it will work with this thread during it's whole lifecycle (i.e: you sent a response).

That's why I think this is a limitation imposed by the browser.

Take a look:

@RestController
@RequestMapping(path = "test")
public class TestController {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @GetMapping
    public ResponseEntity
