JAVA-使用反射为任意对象生成XML

提示

目前只支持基本类型和封装类型

package ztf.question1;import java.io.BufferedWriter;import java.io.FileNotFoundException;import java.io.FileWriter;public class Application {    //存在问题，没有模仿缩进    public static void main(String[] args){        Person person=new Person();        person.setName("ddd");        person.setAge(23);        Address address=new Address("chonqqing","Hong Guang Street");        person.setAddress(address);        System.out.println(ObjectToXml.writeXML(person.getClass(),person));    }}
