初始化 WireMock HTTP 服务器时出现 HttpHostConnectException

HttpHostConnectException when initializing WireMock HTTP server

我正在尝试测试我的代码,该代码具有对 HTTP 服务器的底层 GET 调用。

我正在尝试使用 WireMock,基于 "Getting Started" 我有以下代码:

@Rule
public WireMockRule wireMockRule = 
    new WireMockRule(WireMockConfiguration.wireMockConfig().port(8888)); // No-args constructor defaults to port 8080

@BeforeClass
public static void beforeClass(){
    stubFor(get(urlEqualTo("/Path/Get"))
            .willReturn(aResponse()
                    .withStatus(200)
                    .withBody("[1]")));
}

@Test
public void testGetRanking() throws Exception {
    Fetcher fetcher = new Fetcher("http://localhost:8888",null);
    int rankinganking = fetcher.getRanking("Max");
    Assert.assertEquals(1, ranking);
}

当我 运行 测试时,我得到以下堆栈跟踪:

wiremock.org.apache.http.conn.HttpHostConnectException: Connect to localhost:8080 [localhost/127.0.0.1] failed: Connection refused
at wiremock.org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:151)
at wiremock.org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:353)
at wiremock.org.apache.http.impl.execchain.MainClientExec.establishRoute(MainClientExec.java:380)
at wiremock.org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:236)
...

该错误涉及端口 8080,但我将端口配置为 8888。我知道默认情况下 WireMock 从端口 8080 开始,因此这可能是其内部配置的问题。

这里有什么问题?

这里的问题是 @BeforeClass@rule 之前执行。 将存根移动到 @Before 方法或直接进入测试即可解决问题。
