我正在尝试遵循此仓库https://github.com/jonyfs/spring-boot-jms-sqs中的SQS示例。 我已经将Spring boot升级到2.1.0-RELEASE，并将云依赖性升级到Greenwich.M1。代码运行良好，生成消息并使用它 但是我一直处于例外之下。我尝试了不同的依赖项组合，还添加了客户端配置。

Bad file descriptor。通常，AWS开发工具包会自动重试这样的连接错误，这就是为什么您看不到任何实际影响的原因-它使用全新的连接对其重试。
如果它们偶尔发生一次，请忽略它们。如果它们经常发生，请尝试在ClientConfiguration中使用您的连接设置，以查看减少它们的原因。
我也强烈建议您验证在类路径上存在相同类的多个版本的情况下，没有类路径冲突-由于类加载器如何选择使用哪个类加载器，在运行时可能会发生“有趣”的事情
