網上能查的方法都用過了，比如
linux服務增加下面的內容
#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
錯誤如下：

兩個服務器通信上傳檔案 就報這個錯誤，換臺機器同樣代碼就沒問題。想不通了。uj5u.com熱心網友回復：
使用TCP短鏈接無效。//最后的解決方案是客戶端和服務器統一使用TCP短連接
httppost.setProtocolVersion(HttpVersion.HTTP_1_0);
httppost.addHeader(HTTP.CONN_DIRECTIVE, HTTP.CONN_CLOSE);
uj5u.com熱心網友回復：
你這檔案上傳走的是HTTP啊，最大的可能感覺是檔案太大導致http傳輸超時；你看看你的http呼叫里面timeout值是怎么設定的，這個值在http里面是傳輸時間不是連接超時設定，值改大點看看。uj5u.com熱心網友回復：
下面的方法無效瀏覽器發送請求到servlet，servlet處理時間太久，所以導致chrome瀏覽器出現ERR_CONNECTION_RESET錯誤
解決方案：
在相應servlet執行最后添加一句代碼：
Thread.currentThread().join();
表示必須在當前執行緒執行完之后才回傳頁面到瀏覽器。
uj5u.com熱心網友回復：
鏈接時間改再大也無效int timeout = 60;//這個要弄長點
RequestConfig defaultRequestConfig = RequestConfig.custom()
.setSocketTimeout(timeout * 1000)
.setConnectTimeout(timeout * 1000)
.setConnectionRequestTimeout(timeout * 1000)
.build();
uj5u.com熱心網友回復：
CloseableHttpClient httpclient = HttpClientBuilder.create().setDefaultRequestConfig(defaultRequestConfig).build();HttpPost httppost = new HttpPost(transDto.getWebSiteUrl());
問題肯定出在這里，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, "執行的請求:" + httppost.getRequestLine());
CloseableHttpResponse response = httpclient.execute(httppost);
