I have a running code with spring boot and spring cloud using sleuth to log the TraceId. However i have problems in call one controller from other in the integrationTest
public class TraceIdApp {
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
public static void main(String[] args) {
SpringApplication.run(TraceIdApp.class, args);
}
}
@Slf4j
@Getter
@RestController
public class TraceIdController {
private SpanAccessor spanAccessor;
private RestTemplate restTemplate;
private String url;
@Autowired
public TraceIdController(SpanAccessor spanAccessor, RestTemplate restTemplate,
@Value("http://localhost:${local.server.port:${server.port:8080}}/other") String url) {
this.spanAccessor = spanAccessor;
this.restTemplate = restTemplate;
this.url = url;
}
@GetMapping(path = "/")
public String handlerOne() {
long traceId = spanAccessor.getCurrentSpan().getTraceId();
log.info("loggin the real traceId => " + traceId);
String response = getRestTemplate().getForObject(getUrl(), String.class);
return "one" + response;
}
@GetMapping(path = "/other")
public String handlerOther() {
long traceId = spanAccessor.getCurrentSpan().getTraceId();
log.info("loggin the real traceId => " + traceId);
return "other";
}
}
@Getter
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
public class TraceIdAppTest {
@Autowired
private SpanAccessor spanAccessor;
@Autowired
private MockMvc mockMvc;
@Value("http://localhost:${local.server.port:${server.port:8080}}/other")
String url;
@Test
public void test() throws Exception {
mockMvc.perform(get("/")).andExpect(status().isOk());
assertTrue("trace is wrong type", getSpanAccessor() instanceof DefaultTracer);
}
}
running on test the first i notice its that the port on url take a correct value on the test, however its value is zero on the controller. hardcoding the port didnt fix the problem.
