How to access endpoints in a controller in Spring?

Question

I have a controller class this way with endpoints. I know that we can access RESTful endpoints in a web application through a tool like 'postman' using the URL. But I am not sure how to access these endpoints. This is not a web application.

This is a java application deployed as a JAR on server using embedded tomcat.

How can I access these endpoints?

@Controller
public class TopicStatsController {

    @Autowired
    private QueueDepths depths;

    @RequestMapping("/topicDepth")
    @ResponseBody
    public Long topicDepth() throws Exception {
        return depths.topicDepth();
    }

    @RequestMapping("/subscribersDepth")
    @ResponseBody
    public List<Long> subscribersDepth() throws Exception {
        return depths.subscribersDepth();
    }
}

Answer 1

You can access the endpoints using RestTemplate .

RestTemplate restTemplate = new RestTemplate();
String fooResourceUrl
  = "/topicDepth";
ResponseEntity<String> response
  = restTemplate.getForEntity(fooResourceUrl + "/1", Long.class);

Answer 2

Your remote must be having an IP address and a port number .

You can use it to hit a GET or POST request.

On localhost - http://localhost:8080/myapp-oracle/api/v1/user

On remote - http://172.16.254.1:8080/myapp-oracle/api/v1/user

Note: You also need to change the http protocol depending upon the server.
