Eureka、BOM、Part微服务部署在Azure上。 Eureka 注册微服务，我还可以使用“/service-instances/plm-part-ms”在 bom 微服务中部分微服务详细信息，其中 "plm-part-ms" 是部分微服务的 spring 应用程序名称。任何帮助将不胜感激！
@Santosh，这个问题好像是Azure Webapp的一些限制导致的，比如尝试连接本地地址和机器自己的IP会失败等等，请看here.
根据类似的 SO 线程 ，请尝试使用 Azure Docker 或 Azure Marketplace 的 Pivotal Cloud Foundry 来部署您的 Spring Boot 项目。

Eureka、BOM、Part微服务部署在Azure上。 Eureka 注册微服务，我还可以使用“/service-instances/plm-part-ms”在 bom 微服务中部分微服务详细信息，其中 "plm-part-ms" 是部分微服务的 spring 应用程序名称。任何帮助将不胜感激！
@Santosh，这个问题好像是Azure Webapp的一些限制导致的，比如尝试连接本地地址和机器自己的IP会失败等等，请看here.
根据类似的 SO 线程
创建一个新的 RestTemplate 而不是自动装配它。
