java - 从 Http 响应读取数据很少引发 BindException : Address already in use

Question

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“httpURLConnection.getResponseCode()”会抛出 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 ){
            }

代码运行在Java 1.6，Tomcat 6。 谢谢

去掉 disconnect() 并关闭 Reader。您的本地端口用完了，使用 disconnect() 会禁用 HTTP 连接池，这是解决该问题的方法。
