我正在尝试进行集成测试，以了解当我的注册端点失败时的行为。我的注册端点是一个由外部源提供的 API(由 Spring OAuth 保护)。客户端网站使用客户端 Spring Oauth 与 API 进行通信。

我想做的是模拟 API，但是，我遇到了请求不针对模拟端点的问题； org.springframework.web.client.ResourceAccessException:“http://localhost:8081/oauth/token”的 POST 请求上的 I/O 错误:连接被拒绝:连接；嵌套异常是 java.net.ConnectException: Connection refused: connect。下面是我的测试:

 @WebAppConfiguration
 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations = {"classpath*:RegistrationControllerIntegrationTest-context.xml"})
 public class RegistrationControllerIntegrationTest {


  @Resource
  RegistrationController registrationController;

  @Resource
  private WebApplicationContext webApplicationContext;

  MockMvc mockMvc;

  @Value("${oauth.accessTokenUri}")
  private String oauthUri;

  private MockRestServiceServer mockRestServiceServer;


  private OAuth2RestTemplate clientCredRest;


  @Resource(name = "clientCredentialRest")
  public void setClientCredRest(OAuth2RestTemplate clientCredRest) {
    this.clientCredRest = clientCredRest;
  }



  @Before
  public void setUp()
  {
    this.mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();

    this.mockRestServiceServer = MockRestServiceServer.createServer(this.clientCredRest);


  }
  @Test
  public void testRegistrationThatReturnsBadRequestWhenUserAlreadyExist()
  {




 this.mockRestServiceServer.expect(MockRestRequestMatchers.requestTo("localhost:8081/oauth/token")).andExpect(MockRestRequestMatchers.method(HttpMethod.POST))
    .andRespond(MockRestResponseCreators.withSuccess().contentType(MediaType.APPLICATION_JSON).body("{\n" +
            "\"access_token\": \"8ecd93d4-2484-46de-922a-652fa79d027d\",\n" +
            "\"token_type\": \"bearer\",\n" +
            "\"expires_in\": 1265\n" +
            "\"scope\": \"read write\"\n" +
            "}"));

      Gson gson = Converters.registerDateTime(new GsonBuilder()).create();
      PodamFactory factory = new PodamFactoryImpl();
      RegistrationDTO dto = factory.manufacturePojo(RegistrationDTO.class);
    dto.setUserName("test");
      String json = gson.toJson(dto);


         this.mockRestServiceServer.expect(MockRestRequestMatchers.requestTo("localhost:8081/public/registration")).andExpect(MockRestRequestMatchers.method(HttpMethod.POST))
            .andRespond(MockRestResponseCreators.withBadRequest().contentType(MediaType.APPLICATION_JSON).body("{\n" +
                    "resource: null\n" +
                    "field: \"user_name\"\n" +
                    "code: \"0\"\n" +
                    "message: \"Username already exist\"\n" +
                    "}"));

      MockHttpServletRequestBuilder requestBuilder = MockMvcRequestBuilders.post("/frontend/register").content(json).header("activate", "true").header("User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36").header("Origin","chrome-extension://hgmloofddffdnphfgcellkdfbfbjeloo").contentType(MediaType.APPLICATION_JSON);

      try {
             this.mockMvc.perform(requestBuilder).andExpect(MockMvcResultMatchers.status().isBadRequest());
      } catch (Exception e) {
          e.printStackTrace();
      }
   }
 }

请注意，我为模拟 Web 服务器设置两个期望的原因是由于 Spring Oauth 在向 public/registration 端点发出请求之前获取访问 token 的方式。如果我遗漏了什么，请告诉我。

谢谢。

最佳答案

我自己设置访问 token 对我有用，这会阻止 OAuth2RestTemplate 本身获取访问 token :

@Before
public void before() {
    mockServer = MockRestServiceServer.createServer(oAuth2RestTemplate);
    oAuth2RestTemplate.getOAuth2ClientContext().setAccessToken(
            new DefaultOAuth2AccessToken("accesstoken")
    );
}
