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

Question

我正在尝试遵循此存储库中的 SQS 示例 https://github.com/jonyfs/spring-boot-jms-sqs 。我已将 Spring boot 升级到 2.1.0-RELEASE，并将云依赖项升级到 Greenwich.M1。该代码工作正常，生成消息并使用它但我一直低于异常(exception)。我尝试过不同的依赖项组合并添加客户端配置。

Answer 1

当您使用关闭的套接字时，通常会抛出

错误文件描述符。通常，AWS SDK 会自动重试此类连接错误，这就是为什么您看不到任何实际影响 - 在重试时它会使用新的连接。

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 中调整连接设置，看看是什么减少了它们。

我还强烈建议验证您是否存在某种类路径冲突，即您的类路径上存在相同类的多个版本 - 由于类加载器如何选择使用哪个版本，因此在运行时可能会发生“有趣”的事情.
