如下所示：
// public static void main（string [] args）throws ioexception {datainputStream in = null; outputStream out = null; httpurlconnection conn = null; jsonObject resposetxt = null; inputstream ins = null; bytearrayoutputStream outStream = null; try {url url = new url（ "http://10.28.160.160:9080/main/uploadfile？filename =列表txt"）; conn =（httpurlconnection）url.openconnection（）; //发送post请求必须设置如下两行conn.setdooutput（true）; conn.setusecaches（false）; conn.setRequestMethod（ "post"）; conn.setRequestProperty（ "content-type"、 "text/html"）; conn.setRequestProperty（ "Cache-Control"、 "no-cache"）; conn.setRequestProperty（ "charsert"、 "utf-8"）; conn.connect（）; conn.setConnectTimeout（10000）; out = conn.getOutputStream（）; file file = new file（ "h：/users/chengtingyu/desktop/test/list.txt"）; in = new DatainputStream（new FileInputStream（file））; int bytes = 0; byte [] buffer = new byte [1024]; while（（bytes = in.read（buffer））！= -1）{out.write（buffer、0、bytes）; } out.flush（）; // if（conn.getResponseCode（）== httpurlconnection.http_ok）{ins = conn.getInputStream（）; outStream = new bytearrayoutputStream（）; byte [] data = new byte [1024]; int count = -1; while（（count = ins.read（data、0、1024））！= -1）{outstream.write（data、0、count）; } data = null; resposetxt = jsonobject.parseObject（new String（outstream .tobytearray（）、 "utf-8"））; }} catch（例外e）{e.printstacktrace（）; }最後に{if（in！= null）{in.close（）; } if（out！= null）{out.close（）; } if（ins！= null）{ins.close（）; } if（outstream！= null）{outstream.close（）; } if（conn！= null）{conn.disconnect（）; }}} //文字列filefullpath = "h：/users/chengtingyu/desktop/" + filename; inputstream input = null; fileoutputStream fos = null; try {input = request.getInputStream（）; file file = new file（ "h：/users/chengtingyu/desktop"）; if（！file.exists（））{file.mkdirs（）; } fos = new fileoutputStream（filefullpath）; int size = 0; byte [] buffer = new byte [1024]; while（（size = input.read（buffer、0,1024））！= -1）{fos.write（buffer、0、size）; } // Responsemap.put（ "flag"、true）; //生成响应的JSON sendResponse（jsonresponse）; } catch（ioexception e）{// Responsemap.put（ "flag"、false）; ResponseMap.put（ "Errormsg"、e.getMessage（））; string jsonresponse = jsonobject.tojsonstring（responsemap）; sendResponse（jsonresponse）; }最後に{if（input！= null）{input.close（）; } if（fos！= null）{fos.close（）; }} nullを返します。 }/** *返回响应 * * @throws例外 */private void sendResponse（string responseString）スロー例外{response.setContentType（ "Application/json; charset = utf-8"）; printwriter pw = null; try {pw = response.getWriter（）; pw.write（responsestring）; pw.flush（）; }最後に{ioutils.closequetly（pw）; }}以上这篇利用httpurlconnection上传、希望能给大家一个参考、也希望大家多多支持武林网。
