How to get method URL programmatically in SpringBoot test?-CodePudding

I would like to test my controller with

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class MyTest {

    @LocalServerPort
    int port;

    @Autowired
    TestRestTemplate rest;

    String myUrl = ...;

    @Test
    public void testSequence() {
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        String requesString = ...
        HttpEntity<String> request = new HttpEntity<>( requesString, headers );
        String response = rest.postForObject(myUrl, request, String.class);

here I need to hardcode myUlr with something like

 String.format("http://localhost:%d/my/endpint/path", port);

where my/endpint/path depends on annotations I applied to my controller class and it's methods.

But can I derive it programmatically having class name and method name?

Of course you could extract the @RequestMapping path from your REST controller using reflection and combine it with the path from a handler method in it, but it's really not worth the hassle and it is much easier to put them into public constants and use those to construct the resulting url in your test. Also, constructing an url before testing it is actually a part of the test - you check that your api url looks like you expect it to.

If I understand your question properly the one way which I am aware of is below:

 public static String[] extractWebServiceDetails(HandlerMethod handlerMethod) {
    String methodURI[] = handlerMethod.getMethod().getAnnotation(RequestMapping.class).value();
    return methodURI;
}

Here you can use this at class level for extracting Controller level URI by calling :

public static String[] extractWebServiceDetails(HandlerMethod handlerMethod) {
        String classURI[] = handlerMethod.getClass().getAnnotation(RequestMapping.class).value();
        return classURI;
    }

Only constraint with this is you need to have instance of HandlerMethod for deriving these values.
