写一个小小的框架来玩一玩：

package cn.mengmei.Framework;public class Person {public void run(){System.out.println("run.........");}}

<?xml version="1.0" encoding="UTF-8"?><framework><class name="cn.mengmei.Framework.Person"><method>run</method></class></framework>

package cn.mengmei.Framework;import java.lang.reflect.Method;import org.dom4j.Document;import org.dom4j.Element;import org.dom4j.io.SAXReader;public class MyFramework {public static void main(String[] args) throws Exception {SAXReader reader = new SAXReader();Document document = reader.read("src/config.xml");Element root = document.getRootElement();Element classNode = root.element("class");String className = classNode.attributeValue("name");String methodName = classNode.element("method").getText();Class clazz = Class.forName(className);Method method = clazz.getMethod(methodName, null);method.invoke(clazz.newInstance(), null);}}
