java xml to json(xml 转 json)

代码：

import org.apache.commons.io.FileUtils;

import java.io.File;
import java.io.IOException;

public class Xml2Json {
    public static void main(String[] args) {
        String xml = null;
        try {
            xml = FileUtils.readFileToString(new File("E:\\code\\test\\1.xml"));
            System.out.println(org.json.XML.toJSONObject(xml).toString());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

备注：

maven项目，需要导入响应的包
