问题：
pact-jvm：如何解决au.com.dius.pact.consumer.PactMisMatchesException
裴嘉良
我正在尝试使用Pact-JVM在我们的两个服务之间生成一个协议。但是当我尝试运行Java类时，我得到了这个异常。

我有一个类似的问题，即在测试运行后没有生成协议。我从未使用注释方法使它们工作，而是通过扩展ConsumerPactTestMK2解决了它。Pact将设置mockserver并为您模拟响应。
public class PactForDevice extends ConsumerPactTestMk2 {
Map<String, String> headers = MapUtils.putAll(new HashMap<String, String>(), new String[]{"Content-Type", "application/json;charset=UTF-8"});
public RequestResponsePact createPact(PactDslWithProvider builder) {
return builder
.given("Device M details")
.uponReceiving("retrieving Device details")
.path("/devices/v1")
.method("GET")
.query("externalId=0942dc67-35de-44f7-a061-743f59436a98")
.willRespondWith()
.headers(headers)

使用这种方法，我必须将谷歌番石榴19添加到我的POM中。但效果不错。

我在pact-jvm-consumer中的closeArray有问题。 给定这样的Json，如何构造“dslPart imeiResults=new PactDslJsonBody（）”-语句。 我试过这样： 但这不起作用，例如.closearray（）不返回PactDslJsonBody，而是返回DslPart，所以在.closearray（）之后永远不能有任何东西？我不明白，有人能给我们演示一

所以我有一个包含一些请求和响应数据的json文件，我想要完成的是遍历这些数据并创建一个使用每个请求和响应的pact文件。 所以目前我正在使用junit中的参数化测试来迭代我们的json数据，这基本上是有效的，只是因为生产者名称对于所有pacts都是相同的，它创建了相同的文件并覆盖了前面的文件。 不确定是否有更好的方法来实现这一点，我查看了Github for Pact Jvm并查看了堆栈溢出，但未

我有一个java的Spring BootAPI，它使用pact-jvm进行pact验证。我们有一个新的客户机，他想使用一个新的路径来使用相同的API，网关会处理这个路径，但这会引起pacts的问题，我想截取请求，并修改请求的路径，使新的pacts指向旧的路径。我试图在网上查阅一些资料，发现:https://medium.com/dazn-tech/pact-contract-testing-dea
