AWS Java SDK：调用AmazonSQSClient.receiveMessage时发生AbortedException

Question

我们正在尝试从EC2实例上运行的Java程序的Amazon
SQS队列中读取数据。有时，我们得到一个com.amazonaws.AbortedException。我们的代码如下所示：

AmazonSQSClient sqs = new AmazonSQSClient(myCredentials);
ReceiveMessageRequest request = new ReceiveMessageRequest()
            .withWaitTimeSeconds(20)
            .withMaxNumberOfMessages(1)
            .withQueueUrl(queueUrl);
ReceiveMessageResult result = sqs.receiveMessage(request);

我们的堆栈跟踪如下所示：

的文档com.amazonaws.services.sqs.AmazonSQSClient没有告诉我们期望AbortedException。

我们正在使用SDK版本1.11.77。

任何帮助，将不胜感激。谢谢。

尽管on上的javadoc
AbortedException稀疏，但它是AmazonClientException＆的子类RuntimeException（不必声明）。另外，AWS
Exception处理文档
说：

AmazonClientException表示在尝试向AWS发送请求或解析来自AWS的响应时，Java客户端代码内部发生问题。通常，AmazonClientException比AmazonServiceException更为严重，它表示一个主要问题，该问题阻止客户端对AWS服务进行服务调用。例如，当您尝试在一个客户端上调用操作时，如果没有网络连接可用，则适用于Java的AWS开发工具包将引发AmazonClientException。

AbortedException通常在SDK处理时抛出InterruptedException（即：发出信号通知线程停止工作）。但是出于您的目的，您可能只想重试该操作。

（但是，如果您是明确Thread.interrupt执行此操作的人，则取决于您要如何进行-将其视为停止工作的信号，或者只是重试该操作）
