如果发生以下情况之一，则会出现此问题： 1) 您上传的 json 文件中的消费者/提供者名称存在命名冲突。解决方案：确保名称是唯一的，匹配规则不仅与子字符串匹配有关，而且还捕获“相似名称”。请查看Broker匹配代码以获取更多详细信息。目前还没有这方面的文档。示例：不允许使用 Cart_service 和 order_service，不允许使用 Car-order、order-processing，因为它们有常用词。

2) 如果有任何问题，运行 mvn upload-pacts 将返回 NullPointerException。要查看真正的错误，请确保您运行 mvn test 或 mvn install 。它将向您显示确切的服务器响应状态代码。

有关为具有相似名称的服务发布协议的信息，请参阅此文档：

发布协议时出现 409

当协议正常发布（通过 PUT to /pacts/provider/PROVIDER/consumer/CONSUMER/version/CONSUMER_APP_VERSION）时consumer，会自动创建provider和consumer version资源。

为防止参与者（消费者或提供者）被多次创建并使用略有不同的名称变体（例如 FooBar/foo-bar/foo bar/Foo Bar Service），如果认为新的参与者名称与现有名称足够相似，则409 将被退回。响应正文将包含说明，如果参与者姓名打算是现有姓名，则应更正该参与者姓名，或者如果参与者姓名打算为新姓名，则应手动创建参与者姓名。

不幸的是，一些 Pact Broker 客户端在发生这种情况时不会显示完整的错误文本。全文如下： This is the first time a pact has been published for "%{new_name}". The name "%{new_name}" is very similar to the following existing consumers/providers: %{existing_names} If you meant to specify one of the above names, please correct the pact configuration, and re-publish the pact. If the pact is intended to be for a new consumer or provider, please manually create "%{new_name}" using the following command, and then re-publish the pact: $ curl -v -XPOST -H "Content-Type: application/json" -d '{"name": "%{new_name}"}' http://broker/pacticipants If the pact broker requires authentication, include '-u <username>:<password>' in the command.
