我在AWS beantalk平台上的伦敦地区中部署Spring Boot应用程序，但出现错误：-
“无法实例化[org.springframework.cloud.aws.core.region.StaticRegionProvider]：构造函数引发了异常；嵌套的异常是java.lang.IllegalArgumentException：区域'eu-west-2'不是有效的区域！”
我什至在application.properties文件中放置了cloud.aws.region.static = eu-west-2和cloud.aws.region.auto = false，但错误仍然相同。
请在下面找到详细信息错误：

最佳答案
在Spring Cloud AWS中似乎还没有eu-west-2是受支持的AWS区域。
似乎支持eu-west-1。
可能的区域是（当前）us-east-1，us-west-1，us-west-2，eu-west-1，eu-central-1，ap-southeast-1，ap-southeast-1，ap- northeast-1，sa-east-1，cn-north-1以及配置有自己的区域元数据的任何自定义区域
更新资料
使用Spring Boot 2.2.1.RELEASE和CloudFormation模板here的修改版本，我可以毫无问题地在eu-west-2伦敦AZ本地启动webapp。您可以验证您正在运行的Spring Boot的版本吗？
