xml格式化工具有哪些（ue格式化xml快捷键）

使用的javax这个jar下的类，jaxb（java architecture for xml binding) 这个java和xml的互转标准如果感兴趣可以自行百度这里就不介绍概念，直接上代码。

首先是工具类，这里比较简单，就没做生成实体文件，就是两个，一个对象转xml，一个xml转对像。

import javax.xml.bind.jaxbcontext;
import javax.xml.bind.marshaller;
import javax.xml.bind.unmarshaller;
import java.io.stringreader;
import java.io.stringwriter;
import java.util.arraylist;
import java.util.hashmap;
import java.util.list;
import java.util.map;
