使用您的AWS Access Key和Secret Key创建基础AWS凭证。 使用AmazonS3ClientBuilder构建一个S3客户端,并指定区域。 定义要上传的文件以及目标S3 Bucket的名称。 创建一个PutObjectRequest请求,将文件上传到指定的Bucket。 调用s3Client.putObject(request)进行文件上传操作,并在控制台输出成功信息。 步骤4: 运行代码并验证...

Increasing the max connections can increase client throughput (unless the network interface is already fully utilized), but can eventually start to hit operation system limitations on the number of file descriptors used by the process. If you already are fully utilizing your network interface or cann...
Now we're getting hundreds of errors with a stack trace like the attached. The Client retries and eventually succeeds uploading the file, but I don’t understand what exactly is causing this error to manifest. Stack trace: java.net.SocketException: Connection or outbound has closed ...
