字节到流

得到了 byte[]，转成流：

Java代码  

1. byte[] responseBody = getMethod.getResponseBody();   
2.             SAXReader saxReader = new SAXReader();   
3.             InputStream in = new ByteArrayInputStream(responseBody);   
4.             InputStreamReader strInStream = new InputStreamReader(in, "GBK");  

byte[] responseBody = getMethod.getResponseBody();
			SAXReader saxReader = new SAXReader();
			InputStream in = new ByteArrayInputStream(responseBody);
			InputStreamReader strInStream = new InputStreamReader(in, "GBK");

此时strInStream就可以使用了
