Connection reset谁有办法处理？

[gong0585]

网上能查的方法都用过了，比如
linux服务增加下面的内容
#vi /etc/sysctl.conf
net.ipv4.tcp_syncookies=1
net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_fin_timeout=30
net.ipv4.tcp_keepalive_time=1800
net.ipv4.tcp_max_syn_backlog=4096
错误如下：

两个服务器通信上传文件 就报这个错误，换台机器同样代码就没问题。想不通了。

[gong0585]

使用TCP短链接无效。 //最后的解决方案是客户端和服务器统一使用TCP短连接 httppost.setProtocolVersion(HttpVersion.HTTP_1_0); httppost.addHeader(HTTP.CONN_DIRECTIVE, HTTP.CONN_CLOSE);

你这文件上传走的是HTTP啊，最大的可能感觉是文件太大导致http传输超时；你看看你的http调用里面timeout值是怎么设置的，这个值在http里面是传输时间不是连接超时设置，值改大点看看。

下面的方法无效 浏览器发送请求到servlet，servlet处理时间太久，所以导致chrome浏览器出现ERR_CONNECTION_RESET错误 解决方案： 在相应servlet执行最后添加一句代码： Thread.currentThread().join(); 表示必须在当前线程执行完之后才返回页面到浏览器。

[gong0585]

链接时间改再大也无效 int timeout = 60;//这个要弄长点 RequestConfig defaultRequestConfig = RequestConfig.custom() .setSocketTimeout(timeout * 1000) .setConnectTimeout(timeout * 1000) .setConnectionRequestTimeout(timeout * 1000) .build();

CloseableHttpClient httpclient = HttpClientBuilder.create().setDefaultRequestConfig(defaultRequestConfig).build(); HttpPost httppost = new HttpPost(transDto.getWebSiteUrl()); 问题肯定出在这里，就是不知道是什么原因。 MultipartEntityBuilder build = MultipartEntityBuilder.create().setMode(HttpMultipartMode.BROWSER_COMPATIBLE); for(int i = 0 ; i < fileList.size(); i++){ FileBody filebody = new FileBody(fileList.get(i), ContentType.create("multipart/form-data", "UTF-8")); build.addPart("file"+i, filebody); } StringBody userId = new StringBody(URLEncoder.encode(JSON.toJSONString(transDto), "utf-8"), ContentType.create( "text/plain", Consts.UTF_8)); build.addPart("data", userId); HttpEntity reqEntity = build.setCharset(CharsetUtils.get("UTF-8")).build(); httppost.setEntity(reqEntity); Logger.getLogger(HttpUploadUtils.class.getName()).log(Level.INFO, "执行的请求:" + httppost.getRequestLine()); CloseableHttpResponse response = httpclient.execute(httppost);

请问最后又结论吗 我也遇到这个问题
