报错java.lang.NoClassDefFoundError: org/jaxen/JaxenException

在前端传参xml格式的字符串时

Document document = null;
        SAXReader reader = new SAXReader();
        try {
            document = reader.read(new ByteArrayInputStream(new String(in
                    .getBytes("UTF-8"), "UTF-8").getBytes("UTF-8")));
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
String nodeValue;
        if (document.selectSingleNode(url) == null) {
            nodeValue = "";
        } else {
            nodeValue = document.selectSingleNode(url).getText();
        }
        return nodeValue;

获取子节点时报错，我时采用dom4j解析的，经过查询，缺少依赖，加上就好了
