java.net.ConnectException：拒绝连接：connect（JWT-SpringBoot-OAUTH-Spring Security））

Question

我有这个集成测试：

@RunWith(SpringRunner.class)
@SpringBootTest(classes = ResourceServerApplication.class, webEnvironment = WebEnvironment.RANDOM_PORT)
public class AuthenticationClaimsIntegrationTest {

    @Autowired
    private JwtTokenStore tokenStore;

    @Test
    public void whenTokenDontContainIssuer_thenSuccess() {
        final String tokenValue = obtainAccessToken("clientId", "root", "");
        final OAuth2Authentication auth = tokenStore.readAuthentication(tokenValue);
        System.out.println(tokenValue);
        System.out.println(auth);
        assertTrue(auth.isAuthenticated());
        System.out.println(auth.getDetails());

        Map<String, Object> details = (Map<String, Object>) auth.getDetails();
        assertTrue(details.containsKey("organization"));
        System.out.println(details.get("organization"));
    }

    private String obtainAccessToken(String clientId, String username, String password) {
        final Map<String, String> params = new HashMap<String, String>();
        params.put("grant_type", "password");
        params.put("client_id", clientId);
        params.put("username", username);
        params.put("password", password);
        final Response response = RestAssured.given()
            .auth()
            .preemptive()
            .basic(clientId, "secret")
            .and()
            .with()
            .params(params)
            .when()
            .post("http://localhost:8081/skillsws/oauth/token");
        return response.jsonPath()
            .getString("access_token");
    }

}

当我尝试运行它时，我收到以下错误：

虽然我在SO上轻松了解类似的错误，但我认为它可能是服务器端口问题，因此我添加了以下代码以使用与应用程序使用的8080不同的数字“预先设置”端口：

@LocalServerPort
private int port;

@Before
public void setUp() throws Exception {
    RestAssured.port = port;
}

仍然无法连接。有什么东西我在这里俯瞰吗？

Answer 1

由于您在setUp()方法中配置了端口，因此在创建请求时不应指定整个URL http://localhost:8081/skillsws/oauth/token - 只使用您要测试的路径（没有上下文路径），这可能是/oauth/token。
