java - AWS Java：com.amazonaws.SdkClientException：错误的文件描述符

问题描述

我正在尝试从这个 repo https://github.com/jonyfs/spring-boot-jms-sqs遵循 SQS 示例。我已将 Spring boot 升级到 2.1.0-RELEASE 并将云依赖项升级到 Greenwich.M1。代码工作正常，产生消息并使用它但我一直低于异常。我尝试了不同的依赖组合并添加了客户端配置。

解决方案

Bad file descriptor当您使用关闭的套接字时通常会抛出。通常，AWS SDK 会自动重试这样的连接错误，这就是为什么您没有看到任何实际影响的原因 - 在重试时它使用新连接。

如果它们偶尔发生，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，看看是什么减少了它们。

我还强烈建议验证您没有某种类路径冲突，即类路径上有相同类的多个版本 - 由于类加载器如何选择要使用的类，在运行时可能会发生“有趣”的事情。
