How to send POST request to relative URL with RestTemplate?

How can I send a POST request to the application itself?

If I just send a relative post request: java.lang.IllegalArgumentException: URI is not absolute.

@RestController
public class TestServlet {
    @RequestMapping("value = "/test", method = RequestMethod.GET)
    public void test() {
        String relativeUrl = "/posting"; //TODO how to generate like "localhost:8080/app/posting"?
        new RestTemplate().postForLocation(relativeUrl, null);
    }
}

So using the example above, how can I prefix the url with the absolute server url path localhost:8080/app? I have to find the path dynamically.

If you want to refresh application.properties, you should AutoWire the RefreshScope into you controller, and call it explicitly, it make it much easier to see what it going on. Here is an example

@Autowired
public RefreshScope refreshScope;

refreshScope.refreshAll();

Found a neat way that basically automates the task using ServletUriComponentsBuilder:

@RequestMapping("value = "/test", method = RequestMethod.GET)
    public void test(HttpServletRequest req) {
    UriComponents url = ServletUriComponentsBuilder.fromServletMapping(req).path("/posting").build();
        new RestTemplate().postForLocation(url.toString(), null);
    }

You can rewrite your method like below.

@RequestMapping("value = "/test", method = RequestMethod.GET)
public void test(HttpServletRequest request) {
    String url = request.getRequestURL().toString();
    String relativeUrl = url+"/posting"; 
    new RestTemplate().postForLocation(relativeUrl, null);
}
