各位高手大家好！
请问下在用java HttpURLConection类post数据时刚开时能够顺利完成但是如果联系多次进行就被卡在getInputStream()处无法运行下去，不知道大家在运用时有没有碰到，希望大侠指点。
StringBuffer result = new StringBuffer();
URL httpurl=null;
HttpURLConnection httpConn=null;
try {
httpurl = new URL(url);
httpConn = (HttpURLConnection) httpurl.openConnection();
httpConn.setRequestMethod("POST");
//httpConn.setReadTimeout(5000);
httpConn.setConnectTimeout(30000);
httpConn.setUseCaches(false);

httpConn.setDoOutput(true);
httpConn.setDoInput(true);
httpConn.connect();
OutputStreamWriter outw = new OutputStreamWriter(httpConn.getOutputStream(), "utf-8");
outw.write("line=" + line + "");
outw.flush();
outw.close();
//InputStreamReader re=new InputStreamReader(httpConn.getInputStream(),"utf-8");
/*运行到下面这条语句就不卡主了无法继续运行，如果设置读取时间，当读取时间到时会发生异常，但下次还是会被卡住*/
BufferedReader ins = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), "utf-8"));
// BufferedReader ins = new BufferedReader(re);

String lines;
while ((lines = ins.readLine()) != null) {
result.append(lines);
}
ins.close();
httpConn.connect();

能行的,我运行没有卡住.你再试试

没遇到过类似错误，我只做过获取方面的！没遇过post的，学习！

是不是跟多线程有关，链接次数 少没问题但多了就会出问题啊

你前面输出的都关了，你还要得到哪里的数据？肯定等待数据了。

刚开始是可以运行，连续多次调用后就不能运行下去了，如果设定read时间httpConn.setReadTimeout(5000);时间到后就抛出异常 Read timed out，url为本地的一个jsp页面的url,不知道什么原因
