现在有以下的xml文件, 内容如下:

<iso_10303_28_terse xmlns="urn:oid:1.0.10303.238.1.0.1" xmlns:exp="urn:oid:1.0.10303.28.2.1.1"

现在要求变成json, 最好能变成对象在java代码中进行使用,

//获取xml文件
            InputStream in = new FileInputStream("D:\\mywork\\demo2\\src\\main\\resources\\chengxu.xml");
            String xml = IOUtils.toString(in);
            //把xml变成json
            JSONObject jsonObject = XML.toJSONObject(xml);
            //把json变成一个Map
            Map<String, Object> map = jsonObject.toMap();

这个代码是把整个大的XML变成了一个Map, Map中不断的嵌套, 嵌套的形式和XML中的一致. 比用XML好用, 哈哈哈

本来这个是帮别人写的, 不过最后别人没给钱, 就算了.

依赖的包是:

commons-io-2.4.jar 和 json-20200518.jar
