【问题描述】：

我正在尝试编写一个简单的 pact 测试，但是当我在 runTest 中调用端点时，连接总是被拒绝。看起来 PactProviderRuleMk2 无法正常工作。

public class ConsumerTestCurrencyExchange {

@Rule
public PactProviderRuleMk2 mockProvider = new PactProviderRuleMk2("forexService", "localhost", 8003, this);

@Pact(consumer = "forexServiceClient")
public RequestResponsePact createPact(PactDslWithProvider builder) {
    Map<String, String> headers = new HashMap<String, String>();
    headers.put("Content-Type", "application/json;charset=UTF-8");

    return builder
            .given("Test 1 For Currency Exchange")
                .uponReceiving("Pact JVM example Pact interaction")
                .path("/api/currency-exchange/from/USD/to/EUR")
                .method("GET")
                .headers(headers)
            .willRespondWith()
                .status(200)
                .headers(headers)
                .body(new PactDslJsonBody().stringType("conversionMultiple", "2").asBody())
            .toPact();
}

@Test
@PactVerification()
public void runTest() throws IOException, JSONException {
    System.setProperty("pact.rootDir", "../pacts");
    
    // Connection refused here
    HttpResponse response = Request.Get("http://localhost:8003/api/currency-exchange/from/USD/to/EUR").execute().returnResponse();
    
    
    String json = EntityUtils.toString(response.getEntity());
    JSONObject jsonObject = new JSONObject(json);
    String conversionMultiple = jsonObject.get("conversionMultiple").toString();

    assertEquals(conversionMultiple, "2");
}}

这是堆栈跟踪：

依赖：（我尝试了不同的版本，但结果是一样的）

    <dependency>
        <groupId>au.com.dius</groupId>
        <artifactId>pact-jvm-consumer-junit_2.12</artifactId>
        <version>3.5.10</version>
