如何通过SpringBootTest调试Spring Boot应用程序

Question

@RunWith(SpringRunner.class)
@SpringBootTest(classes = NewBusinessRevitalizationApplication.class, 
    webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@TestPropertySource(properties = {"management.port=0"})
public class NBRControllerTest extends TestCase {

    @LocalServerPort
    private int port;

    @Value("${local.management.port}")
    private int mgt;

    @Autowired
    private TestRestTemplate testRestTemplate;

    @Test
    public void getApplicationByAgencyIdAndStatusTest() {
        String uri = "http://localhost:" + this.port + "/nbr-services/applications/{status}?agencyIds=123456,56765,678576";
        Map<String, String> vars = new HashMap<String, String>();
        vars.put("status", "SAVED");
        ResponseEntity<String> response = testRestTemplate.getForEntity(uri, String.class, vars);
        assertEquals(HttpStatus.OK, response.getStatusCode());
    }
}

@RestController
@RequestMapping("/nbr-services")
public class NBRController {

    @Autowired
    private NBRServices nbrServices;

    private static Logger logger = LoggerFactory.getLogger(NBRController.class);

    @RequestMapping(value = "/configuration/environment/{environment}", method = RequestMethod.GET)
    @ResponseBody
    public String getConfiguration(@PathVariable("environment") String environment) throws RemoteException {
        logger.debug("environment={}", environment);
        String result = nbrServices.getConfiguration(environment);
        return result;
    }
}

当我意外地有两个控制器方法具有相同的路径映射时，我就发生了这种情况。

调试的其他备选方案：

通过不使用拆分的webEnvironment，而是使用spring MockMVC对控制器进行直接方法调用而不是http调用来调试系统是可能的。

@SpringBootTest(
   webEnvironment = SpringBootTest.WebEnvironment.MOCK // this is the default
)
@AutoConfigureMockMvc
class MyTest {

  @Autowired
  private MockMvc mockMvc;

  @Test public void myTest() {
     mockMvc.perform("/mypath");
     // ...
  }
}
