dom4j

开源xml解析包，把整个xml文档当成一个对象，把内容一次性装载进内存

xml转map

Map<String, String> map = new HashMap<>();
SAXReader reader = new SAXReader();

InputStream ins = request.getInputStream();
Document doc = reader.read(ins);
//获取根节点
Element root = doc.getRootElement();
List<Element> list = root.elements();
for (Element e : list) {
	map.put(e.getName(), e.getText());
}
ins.close();
