java做微信开发时报错说HierarchicalStreamDriver类不存在，不知道怎么解决

Question

massageUtil.java

  @SuppressWarnings("unchecked")  
    public static Map<String, String> parseXml(HttpServletRequest request) throws Exception {  
        // 将解析结果存储在HashMap中  
        Map<String, String> map = new HashMap<String, String>();  

        // 从request中取得输入流  
        InputStream inputStream = request.getInputStream();  
        // 读取输入流  
        SAXReader reader = new SAXReader();  
        Document document = reader.read(inputStream);  
        // 得到xml根元素  
        Element root = document.getRootElement();  
        // 得到根元素的所有子节点  
        List<Element> elementList = root.elements();  

        // 遍历所有子节点  
        for (Element e : elementList)  
            map.put(e.getName(), e.getText());  

        // 释放资源  
        inputStream.close();  
        inputStream = null;  

        return map;  
    }
