升级Swagger打破了Spring Cloud（Eureka，Zuul，Ribbon）

我有两个Spring Boot应用程序，一个用作另一个的反向代理 . 我正在使用Spring Boot（1.4.1.RELEASE），Spring Cloud（Camden.SR1） . 我使用的是Swagger 2.5.0，一切都按预期工作 . 我的BootA应用程序托管了Eureka Server并包含Zuul映射，成功地将收到的请求转发到BootB应用程序 .

但是，如果我将Swagger升级到2.6.0，事情就会开始失败 . 首先，当我查看Eureka Dashboard时，BootB应用程序显示为“Unknown” . 实际上，在我的BootB的application.properties中，我没有定义eureka.instance.appname . 如果我在BootB的application.properties中定义它，应用程序将正确显示在Eureka Dashboard中 . 然而，Zuul使用的Load Balancer无法找到服务器BootB . 我收到一个ZuulException（转发错误），它是由netflix客户端的客户端异常引起的

我在调试中运行了netflix组件，在使用Swagger 2.6.0时我没有看到BootB服务器，但我可以看到它是在旧版本中找到的 .

虽然我想在Swagger中修复一些错误，但这会阻止我使用它 . 分配eureka.instance.appname听起来像我正在治疗症状 . 任何人都可以指出我让这些组件协同工作的正确方向？从表面上看，我不明白为什么Swagger会影响Zuul，但我很难找到任何根本原因 . 谢谢你的帮助 .
