请参阅有关为具有类似名称的服务发布契约的文档：

409在发布协议时

当pact正常发布时(通过PUT to /pacts/provider/PROVIDER/consumer/CONSUMER/version/CONSUMER_APP_VERSION)，consumer、provider和consumer version资源将自动创建。

为了防止使用稍微不同的名称变体(例如，用户或提供者)多次创建pacticipant (消费者或提供者)。( FooBar/foo- Bar /foo bar/Foo Bar服务)，如果新的参与者名称被认为与现有名称非常相似，则将返回一个409。响应机构将包含指示，说明如果拟为现有名称，则应更正pacticipant名称；如果拟为新名称，则应手动创建该pacticipant名称。

不幸的是，当发生这种情况时，一些clients客户端没有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.

如果发生以下情况之一，就会出现此问题: 1)您要上载的json文件中的使用者/提供者名称中存在命名冲突。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相关，而且还捕获“相似名称”.Please检查代理匹配代码以获得更多详细信息。目前还没有这方面的文件。例如: Cart_service和order_service是不允许的，汽车订单和订单处理是不允许的，因为他们有共同的词汇.

2)如果有任何问题，运行mvn上传协议将返回NullPointerException。要查看真正的错误，请确保您运行的是mvn测试或mvn安装。它将显示准确的服务器响应状态代码。
