ClientAbortException Connection reset by peer: socket write error

时间：2024-03-20 11:33:24

最近在整合和上传下载相关的工具类，做了个小demo，如图

 


ClientAbortException Connection reset by peer: socket write error
 

 

 

点击 download链接，程序自动下载使用outputStream write 一个那片海.mp4，这个mp4 大概  44.76MB

 

代码如下：

  

private int					i	= 0;

	@RequestMapping("/download")
	public void download(HttpServletRequest request,HttpServletResponse response) throws IOException{
		i++;
		log.info("access i:{}", i);

		String pathname = null;

		pathname = "D:\\Downloads\\那片海.mp4";
		pathname = "C:\\Users\\feilong\\Downloads\\那片海.mp4";
		//pathname = "D:\\Downloads\\viewfile.png";
		//pathname = "D:\\Downloads\\export-飞天奔月.opml";

		//int contentLength = inputStream.available();

		File file = new File(pathname);
		int contentLength = (int) FileUtil.getFileSize(file);

		// 以流的形式下载文件。
		InputStream inputStream = new FileInputStream(pathname);
		String saveFileName = FileUtil.getFileName(pathname);

		download(saveFileName, inputStream, contentLength, request, response);
	}

 

 

 

普通的IE浏览器下载，不会出现问题，但是如果是迅雷下载，或者是 360极速浏览器开了  “使用迅雷下载加速模块”功能

日志里面瞬间就会出现 10个相同的请求

并且 log中会报  异常

 究其原因：

 

 

/*
 * 在写数据的时候， 对于 ClientAbortException 之类的异常， 是因为客户端取消了下载，而服务器端继续向浏览器写入数据时， 抛出这个异常，这个是正常的。
 * 尤其是对于迅雷这种吸血的客户端软件， 明明已经有一个线程在读取
 * 如果短时间内没有读取完毕，迅雷会再启第二个、第三个。。。线程来读取相同的字节段，
 * 直到有一个线程读取完毕，迅雷会 KILL掉其他正在下载同一字节段的线程， 强行中止字节读出，造成服务器抛 ClientAbortException。
 */

 

 

这对项目是不小的一笔开销 （从日志中可以看到，每个相同的请求 都会过 下 Interceptor）

 

 

对于这种异常，我们可以在代码中忽略掉，避免 log太多了，代码示例如下:

 

  

try{
			OutputStream outputStream = response.getOutputStream();

			//这种 如果文件一大，很容易内存溢出
			//inputStream.read(buffer);
			//outputStream = new BufferedOutputStream(response.getOutputStream());
			//outputStream.write(buffer);

			IOWriteUtil.write(inputStream, outputStream);
			if (log.isInfoEnabled()){
				Date endDate = new Date();
				log.info(
								"end download,saveFileName:[{}],contentLength:[{}],time use:[{}]",
								saveFileName,
								FileUtil.formatSize(contentLength),
								DateExtensionUtil.getIntervalForView(beginDate, endDate));
			}
		}catch (IOException e){

			//ClientAbortException:  java.net.SocketException: Connection reset by peer: socket write error
			final String exceptionName = e.getClass().getName();

			if (StringUtil.isContain(exceptionName, "ClientAbortException") || StringUtil.isContain(e.getMessage(), "ClientAbortException")){
				log.warn(
								"[ClientAbortException],maybe user use Thunder soft or abort client soft download,exceptionName:[{}],exception message:[{}] ,request User-Agent:[{}]",
								exceptionName,
								e.getMessage(),
								RequestUtil.getHeaderUserAgent(request));
			}else{
				log.error("[download exception],exception name: " + exceptionName, e);
				throw e;
			}
		}

 

 

网站是时候禁用迅雷下载了
