1、一个标签对应一个标签模型类

2、属性为String类型，子元素标签则是map类型，子元素标签的唯一标识则为map的键，子元素对应的模型类是map的值

3、通过一个根标签工厂类实例化一个根标签类（在创建根标签的时候，就是建模的过程，说白了就是将xml封装成对象）

核心代码

public class ConfigModelFactory {
	
	public static ConfigModel build() throws Exception {
		return build("config.xml");
	}

	public static ConfigModel build(String xmlPath) throws Exception {
		ConfigModel configModel = new ConfigModel();
		InputStream in = ConfigModelFactory.class.getResourceAsStream(xmlPath);
		SAXReader saxReader = new SAXReader();
		Document doc = saxReader.read(in);
		ActionModel actionModel = null;
		ForwardModel forwardModel = null;
		List<Element> actionEles = doc.selectNodes("/config/action");
		for (Element actionEle : actionEles) {
			actionModel = new ActionModel();
			//接下来需要往actionModel中填充内容
			actionModel.setPath(actionEle.attributeValue("path"));
			actionModel.setType(actionEle.attributeValue("type"));
			List<Element> forwardEles = actionEle.selectNodes("forward");
			for (Element forwardEle : forwardEles) {
				forwardModel = new ForwardModel();
				//接下来需要往forwardModel中填充内容
				forwardModel.setName(forwardEle.attributeValue("name"));
				forwardModel.setPath(forwardEle.attributeValue("path"));
				forwardModel.setRedirect(!"false".equals(forwardEle.attributeValue("redirect")));
				actionModel.push(forwardModel);
			}
			
			configModel.push(actionModel);
		}
		
		return configModel;
	}
	
	public static void main(String[] args) throws Exception {
		ConfigModel configModel = ConfigModelFactory.build();
		ActionModel actionModel = configModel.pop("/loginAction");
		System.out.println(actionModel.getType());
		ForwardModel forwardModel = actionModel.pop("a");
		System.out.println(forwardModel.getPath() + "   " + forwardModel.isRedirect());
		
	}
