[英]problem with spring boot/microservices and eureka
我在 intellij 中运行了 2 个 spring boot/微服务。 这两项服务启动时都没有错误。 但是，如果第一个微服务尝试从第二个微服务调用服务，我会收到错误消息。 有任何想法吗？ 该代码在测试环境中运行良好，但在我的本地计算机上出现以下错误。 我不知道应该从哪里开始寻找错误。 两个微服务都在尤里卡注册，状态为“UP”。 如果我将异常中显示的 URL 复制到浏览器，则不会出现连接超时。 所以我认为问题出在 intellij 的某个地方，但我不知道什么地方可以“阻止”我的请求。 我正在使用 openjdk 8。任何提示都很好，谢谢

很难说到底是什么问题，如果您提供更多有关配置的信息，那将是很好的。 由于是连接超时错误，建议在application.properties中设置feign超时：
feign.client.config.default.connectTimeout: 160000000
查看类似的问题： feign.RetryableException: Read timed out executing GET
发现了错误...我有
-Djava.net.preferIPv4Stack=true
在虚拟机选项...没有此设置，它工作正常。
