How to receive viber REST API callbacks (using java, spring)?

I'm trying to make viber bot (public account) using java/spring. I succeed with setting webhook for the bot (by deploying it to heroku and making post request

{ "url":"https://my.host.com" }

using Postman) and now I'm trying to receive messages from users. The problem is that I'm a newbie in using spring and don't actually know how to receive any viber events.

Here is my code (just checking if I can receive viber callbacks): 

@RestController 
@SpringBootApplication 
public class DemoApplication {

public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);
}

@RequestMapping
public String request(@RequestHeader("X-Viber-Content-Signature") String serverSideSignature) {
    System.out.println("Here we go!");
    System.out.println(serverSideSignature);
    return "Hello world!";
}
}

However, this doesn't works. If I make request with required serverSideSignature(example from documentation) using Postman, such as

{ "event":"message", "timestamp":1457764197627, "message_token":4912661846655238145, "sender":{ "id":"01234567890A=", "name":"John McClane", "avatar":"http://avatar.example.com", "country":"UK", "language":"en", "api_version":1 }, "message":{ "type":"text", "text":"a message to the service", "media":"http://example.com", "location":{ "lat":50.76891, "lon":6.11499 }, "tracking_data":"tracking data" } },

I can see an console output. But it does not work if I send message to bot (don't even get any information from logs). I guess the problem is that I do not understand properly how viber sends any information to my webhook, but maybe there is someone who can explain that for me? Thanks a lot.

P.S. Viber REST API documentation

@RequestMapping uses GET method by default and Viber sends a callback to a webhook using POST method. Try to change @RequestMapping to @PostMapping and of course, you should be sure that your webhook is set correctly and your URL has a valid and official SSL certificate from a trusted CA.
