AWS Java SDK:调用AmazonSQSClient.receiveMessage时异常中止

我们试图从运行在EC2实例上的Java程序中读取AmazonSQS队列。有时，我们会得到一个

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);

的文档没有告诉我们预期异常会中止

我们使用的是SDK版本1.11.77

任何帮助都将不胜感激。谢谢

虽然上的javadoc是稀疏的，但它是

AmazonClientException

和

RuntimeException

的子类（不必声明）。此外，报告说：

AmazonClientException表示Java客户端代码中出现问题，可能是在尝试向AWS发送请求时，也可能是在尝试解析来自AWS的响应时。AmazonClientException通常比AmazonServiceException更严重，它表示一个主要问题，即阻止客户端对AWS服务进行服务调用。例如，当您尝试调用其中一个客户端上的操作时，如果没有可用的网络连接，AWS SDK For Java会抛出AmazonClientException

AbortedException

通常在SDK处理

interruptedeexception

（即：）时引发。不过，出于您的目的，您可能只想重试该操作

（如果是您执行显式

线程。中断
导致此问题，则由您决定如何继续-将其视为停止工作的信号，或只是重试该操作）
