【问题描述】：

刚开始使用 Amazon S3。尝试使用简单的 java 方法从 Amazon S3 访问文件时出现以下错误。

2016-08-23 09:46:48 INFO  request:450 - Received successful response:200, AWS Request ID: F5EA01DB74D0D0F5
Caught an AmazonClientException, which means the client encountered an   
internal error while trying to communicate with S3, such as not being 
able to access the network.
Error Message: Unable to store object contents to disk: Read timed out

昨天的确切代码行有效。我能够在 12 分钟内下载 100% 的 5GB 文件。今天我在一个更好的连接环境中，但只下载了 2% 或 3% 的文件，然后程序就失败了。

我用来下载的代码。

s3Client.getObject(new GetObjectRequest("mybucket", file.getKey()), localFile);

【解决方案1】：

您需要在客户端配置中设置连接超时和套接字超时。

Here is an excerpt from the article:

Several HTTP transport options can be configured through the com.amazonaws.ClientConfiguration object. Default values will suffice for the majority of users, but users who want more control can configure: 
Socket timeout
Connection timeout
Maximum retry attempts for retry-able errors
Maximum open HTTP connections

下面是一个例子：

Downloading files >3Gb from S3 fails with "SocketTimeoutException: Read timed out"

对此的推荐设置是什么？ Java DOC 说A value of 0 means infinity, and isn't recommended，那么如何避免这个错误呢？
目前的默认值是50 seconds，可以这样解决吗：stackoverflow.com/questions/40500888/…
