Spring Boot-Spring Cloud AWS：未找到区域

Question

我有一个Spring Boot，Spring Cloud AWS服务，用于接收来自AWS SQS队列的消息。在我自己的个人AWS账户服务中，一切都很好，区域设置为“us-east-1”，但是当切换到AWS GovCloud区域“us-gov-east-1”时，收到错误消息“该区域“us-gov-east-1”不是一个有效的区域”。追踪到与拉取真实旧版本的aws-java-sdk-core-1.11.415库有关的问题，该库在其Regions.enum对象中不包含新的GovCloud区域。不太确定为什么这个项目会引入aws-java-sdk-core-1.11.415的一个非常旧的传递依赖项，因为我相信Spring-Cloud项目会引入aws-java-sdk-core-1.11.7xx。当然，我可能在我的pom.xml配置中做了一些错误的事情，但是我似乎不明白为什么这个项目会引入旧版本的aws-java-sdk-core库。

我一直在运行初始测试目的，默认区域设置为没有问题：

cloud.aws.region.static=us-east-2

但是，我们正在尝试将 Docker 容器服务迁移到新的 AWS GovCloud 区域：

cloud.aws.region.static=us-gov-east-1

我在运行时遇到以下错误：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.aws.core.region.StaticRegionProvider]: Constructor threw exception; nested exception is java.lang.IllegalArgumentException: The region 'us-gov-east-1' is not a valid region!

感谢您的任何帮助。

要追踪旧版本的AWSJavaSDK在您的代码中泄漏的位置，请执行mvn依赖项：树。研究这棵树，看看它来自哪里。

要强制使用最新版本的AWS Java SDK，请将其BOM导入到dependenciesManagement：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.amazonaws</groupId>
            <artifactId>aws-java-sdk-bom</artifactId>
            <version>1.11.808</version>
            <type>pom</type>
        </dependency>
    </dependencies>
</dependencyManagement>

在官方文件和这个SO线程中阅读更多关于BOM的信息。
