java反射获取xml元素

类名:

class Person {
	
	public void run(String who){
		System.out.println("Person::run()" + who);
	}
	public void jump(String who){
		System.out.println("Person::jump()" + who);
	}

	
	public void run(){
		System.out.println("Person::run()");
	}
	public void jump(){
		System.out.println("Person::jump()");
	}
}

配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<root>
	<class>
		<className>day2.mode1.Person</className>
		<methodName>jump</methodName>
		<argType>java.lang.String</argType>
		<argValue>李玟</argValue>
	</class>
</root>

测试类：

import java.io.File;
import java.lang.reflect.Method;
import org.dom4j.Document;
import org.dom4j.io.SAXReader;
import org.junit.Test;

//使用dom4j和反射技术
public class Demo1 {
	
	//解析xml文件
	@Test
	public void fanse() throws Exception
	{
		SAXReader saxReader = new SAXReader();
		Document document = saxReader.read(new File("src/day2/mode1/config.xml"));
	    
		String className = document.selectSingleNode("//className").getText();
		String methodName = document.selectSingleNode("//methodName").getText();
		//System.out.println(className + ":" + methodName);
			
		//反射创建对象并执行方法
		Class clazz = Class.forName(className);
		Method method = clazz.getMethod(methodName,null);
		method.invoke(clazz.newInstance(),null);
	}

	   //解析xml文件  参数
		@Test
		public void fanse2() throws Exception
		{
			SAXReader saxReader = new SAXReader();
			Document document = saxReader.read(new File("src/day2/mode1/config.xml"));
		    
			String className = document.selectSingleNode("//className").getText();
			String methodName = document.selectSingleNode("//methodName").getText();
			//System.out.println(className + ":" + methodName);
				
			//参数
			
			String argType = document.selectSingleNode("//argType").getText();
			String argValue = document.selectSingleNode("//argValue").getText();
			//反射创建对象并执行方法
			Class clazz = Class.forName(className);
			Method method = clazz.getMethod(methodName,Class.forName(argType));
			method.invoke(clazz.newInstance(),argValue);
