InputStreamReader isr = new InputStreamReader(is, "UTF-8");

贴上整个调用接口的代码，如下，也是一般的使用HttpURLConnection调用Webservice接口的代码

public String callInterface(String URL, String requestMethod, String contentType, String SOAPAction, String soapXml) throws IOException{
	String result = "";
	//第一步：创建服务地址
	URL url = new URL(URL);
	//第二步：打开一个通向服务地址的连接  

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();  

        //第三步：设置参数  

        //3.1发送方式设置：POST必须大写  

        connection.setRequestMethod(requestMethod);  

        //3.2设置数据格式：content-type  SOAPAction

        connection.setRequestProperty("content-type", contentType);

        connection.setRequestProperty("SOAPAction", SOAPAction);

        //3.3设置输入输出，因为默认新创建的connection没有读写权限，  

        connection.setDoInput(true);  

        connection.setDoOutput(true);  

        //第四步：组织SOAP数据，发送请求  

        System.out.println("requestXml:"+soapXml);

        connection.connect();//可能非必须

        //将信息以流的方式发送出去

        OutputStream os = connection.getOutputStream();  

        os.write(soapXml.getBytes("UTF-8"));  

        os.flush();

        os.close();

        //第五步：接收服务端响应，打印  

        int responseCode = connection.getResponseCode();  

        if(200 == responseCode){//表示服务端响应成功  

        	//获取当前连接请求返回的数据流

            InputStream is = connection.getInputStream();  

            InputStreamReader isr = new InputStreamReader(is, "UTF-8");  

            BufferedReader br = new BufferedReader(isr);  

              

            StringBuilder sb = new StringBuilder();  

            String temp = null;  

            while(null != (temp = br.readLine())){  

                sb.append(temp);  

            }  

            /**

             * 打印结果

             */

            //response = sb.toString();

            result = sb.toString();

            System.out.println("返回XML："+ sb.toString());  

            is.close();  

            isr.close();  

            br.close(); 

        }  

        os.close();
	return result;
}
