我目前正在使用 Spring 4.1.4 使用 STS 3.6.3SR1。尝试测试 spring-cloud-aws 在我们的应用程序中使用的可行性。
与问题相关的罐子：
- spring-cloud-aws-autoconfigure-1.0.0.RC2.jar
- spring-cloud-aws-context-1.0.0.RC2.jar
- spring-cloud-aws-core-1.0.0.RC2.jar
- spring-cloud-aws-messaging-1.0.0.RC2.jar
使用 aws-sdk-1.9.19
这是我在 spring-cloud-aws starter page之后的 applicationContext 文件。
<aws-context:context-region region="us-east-1"/>
<aws-context:context-credentials>
<aws-context:simple-credentials
access-key="*******" secret-key="*******"/>
</aws-context:context-credentials>
<aws-messaging:queue-messaging-template id="queueMessagingTemplate" />
<aws-messaging:annotation-driven-queue-listener />
Spring-cloud-aws 的起始页建议 queuemessagingtemplate bean 在使用消息传递命名空间时会自动注入一个 AmazonSQS bean。但是，据我了解，我遇到了关于将字符串值区域转换为 AWS 枚举值区域的错误。
以下是相关日志：

有人可以阐明我的上下文文件是否不正确吗？我相信us-east-1是指定区域的正确方法，但我错过了什么吗？
谢谢你。
