从Http中读取数据响应很少抛出BindException：地址已在使用中

问题描述

我使用以下代码从http请求中读取数据。
在一般情况下它运行良好，但有时候httpURLConnection.getResponseCode（）会抛出java.net.BindException：地址已在使用中：connect

I use following code to read data form http request.In general cases it works good, but some time "httpURLConnection.getResponseCode()" throws java.net.BindException: Address already in use: connect

     ............
     URL url = new URL( strUrl );
     httpURLConnection = (HttpURLConnection)url.openConnection();
     int responseCode = httpURLConnection.getResponseCode();
     char charData[] = new char[HTTP_READ_BLOCK_SIZE];
     isrData = new InputStreamReader( httpURLConnection.getInputStream(), strCharset );
     int iSize = isrData.read( charData, 0, HTTP_READ_BLOCK_SIZE );
     while( iSize > 0 ){
            sbData.append( charData, 0, iSize );
            iSize = isrData.read( charData, 0, HTTP_READ_BLOCK_SIZE );
     }
     .................





 finally{
            try{
                if( null != isrData ){
                    isrData.close();
                    isrData = null;
                }

                if( null != httpURLConnection ){
                    httpURLConnection.disconnect();
                    httpURLConnection = null;
                }

                strData = sbData.toString();
             }
            catch( Exception e2 ){
            }

在Java 1.6，Tomcat 6上运行的代码。
谢谢

The code running on Java 1.6, Tomcat 6.Thank you

推荐答案

摆脱disconnect（）并关闭读者而不是。您正在耗尽本地端口，并使用disconnect（）禁用HTTP连接池，这是解决方案。

Get rid of the disconnect() and close the Reader instead. You are running out of local ports, and using disconnect() disables HTTP connection pooling which is the solution to that.
