有人可以给我提供代码示例，以编写针对使用HTTPS进行保护的控制器的集成测试吗？使用HTTP可以写，但是使用HTTPS可以得到认证错误。

控制者

@RestController
@RequestMapping("/rest/otm/v1")
public class LoginController {

    @Autowired
    UserAuthenticationService userAuthService;

    @ExceptionHandler({ AuthenticationFailedException.class})
    @RequestMapping(value = "/login", method = RequestMethod.POST)
    @ResponseBody
    public void login(HttpServletRequest request,HttpServletResponse response) throws AuthenticationDeniedException {

        //some code
    }

}

测试班

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
@IntegrationTest("server.port:0") 
public class IdentityControllerTest {

    @Value("${local.server.port}")
    int port;

    @Test
    public void test_Login_Controller() {

        SimpleClientHttpRequestFactory clientHttpRequestFactory = new SimpleClientHttpRequestFactory();

        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("some-proxy", 8080));
        clientHttpRequestFactory.setProxy(proxy);

        RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);

        HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.set("credential", "pratap");
        requestHeaders.set("deviceid", "xyz123");

        HttpHeaders response = restTemplate.postForObject("https://localhost:"+port+"/rest/otm/v1/login", requestHeaders, HttpHeaders.class);

    }

}

错误

org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://localhost:51184/rest/otm/v1/login":sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
