Question

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();

public static void main(String[] args) {
// TODO Auto-generated method stub
StringBuffer result = new StringBuffer();
URL httpurl=null;
HttpURLConnection httpConn=null;
try {
httpurl = new URL("http://www.123.com");
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("keywords=help");
// 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);
}
System.out.println(result.toString());
ins.close();
httpConn.connect();
} catch (IOException e) {
System.out.println(e);
} }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！

Answer 3

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
