问uploadPart失败，无法执行HTTP请求:连接重置

EN

我正在尝试使用多部分上传AWS S3 java执行文件上传(我使用的是SDK1.8.1)。我能够成功地执行上传。

但是，我断断续续地得到了这个例外。

7月31日，2014年4:39:38 AM com.amazonaws.http.AmazonHttpClient executeHelper信息:无法执行HTTP请求:连接重置java.net.SocketException:连接重置在java.net.SocketInputStream.read(SocketInputStream.java:121) at sun.security.ssl.InputRecord.readFully(InputRecord.java:312) at sun.security.ssl.InputRecord.read(InputRecord.java:350) at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:927)在sun.security.ssl.SSLSocketImpl.readDataRecord(SSLSocketImpl.java:884) at sun.security.ssl.AppInputStream.read(AppInputStream.java:102) at org.apache.http.impl.io.AbstractSessionInputBuffer.fillBuffer(AbstractSessionInputBuffer.java:166) at org.apache.http.impl.io.SocketInputBuffer.fillBuffer(SocketInputBuffer.java:90) at org.apache.http.impl.io.AbstractSessionInputBuffer.readLine(AbstractSessionInputBuffer.java:281) at org.apache.http.impl.conn.DefaultHttpResponseParser.org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:62) at org.apache.http.impl.io.AbstractMessageParser.parse(AbstractMessageParser.java:254) org.apache.http.impl.AbstractHttpClientConnection.receiveResponseHeader(AbstractHttpClientConnection.java:289) at org.apache.http.impl.conn.DefaultClientConnection.receiveResponseHeader(DefaultClientConnection.java:252) at org.apache.http.impl.conn.ManagedClientConnectionImpl.receiveResponseHeader(ManagedClientConnectionImpl.java:191 parseHead(DefaultHttpResponseParser.java:92))在org.apache.http.protocol.HttpRequestExecutor.doReceiveResponse(HttpRequestExecutor.java:300) at com.amazonaws.http.protocol.SdkHttpRequestExecutor.doReceiveResponse(SdkHttpRequestExecutor.java:66) at org.apache.http.protocol.HttpRequestExecutor.execute(HttpRequestExecutor.java:127) at org.apache.http.impl.client.DefaultRequestDirector.tryExecute(DefaultRequestDirector.java:717) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:522) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:906) at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:805) at com.amazonaws.http.AmazonHttpClient.executeHelper(AmazonHttpClient.java:402) at com.amazonaws.http.AmazonHttpClient.execute(AmazonHttpClient.java:245) at com.amazonaws.services.s3.AmazonS3Client.invoke(AmazonS3Client.java:3711) at com.amazonaws.services.s3.AmazonS3Client.uploadPart(AmazonS3Client.java:2809) at cloud<-filename->.writeContent(<-filename->.java:<-linenumber->)

在以下代码中

try {
                  _partETags.add(_s3.uploadPart(uploadPartReq).getPartETag());
      } catch (AmazonClientException e) {
                  System.out.println("Amazon service error. Retrying...");
                  printException(e);
      } catch (Exception e) {
                  printException(e);
                  throw new UserException("Received an exception while performing upload part");
      }

如果我看一下文档化，它会说uploadPart函数只会抛出两个类AmazonClientException和AmazonServiceException。

链接：http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/AmazonS3.html#uploadPart(com.amazonaws.services.s3.model.UploadPartRequest)

..。UploadPartResult uploadPart(UploadPartRequest request)抛AmazonClientException，AmazonServiceException .抛出: AmazonClientException --如果在进行请求或处理响应时客户端遇到任何错误。AmazonServiceException --如果在处理请求时亚马逊S3中发生了任何错误。..。

但是，我收到了不同的例外。

我有以下问题

• 这是否是一种预期的行为，如果不是，我如何解决这个问题？
• 为什么我的try catch块不能捕获这个异常？
• 在AmazonClient或AmazonServiceException的情况下，是建议我们重新尝试上传，还是认为这些都是不可恢复的错误？
