SpringBoot: Timeout when the endpoint doesn't return a response

Question

I am new to SpringBoot and looking for a way to Timeout when endpoint takes more than 3 seconds to return the response. I tried by adding the property "server.servlet.session.timeout", but still no luck. How to achieve this? Thanks.

@GetMapping("/api")
public Data getData(){

    Thread.sleep(10000);

    return ....;
}

Application.properties

server.servlet.session.timeout=3s

Not sure what your http client looks like. (RestTemplate/WebClient). But using WebClient this is how you can create TimeOut for your need.

HttpClient client = HttpClient.create()
  .option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 3000);
