XmlJSON 工具类

import net.sf.json.JSONObject;import net.sf.json.xml.XMLSerializer;public class XmlJSON {    public static String xmlToJson(String xml) {        XMLSerializer serializer = new XMLSerializer();        return serializer.read(xml).toString();    }    public static String jsonToXML(String json) {        JSONObject jobj = JSONObject.fromObject(json);        XMLSerializer xmlSerializer = new XMLSerializer();        // 根节点名称        xmlSerializer.setRootName("xml");        // 不对类型进行设置        xmlSerializer.setTypeHintsEnabled(false);        String xmlStr=xmlSerializer.write(jobj);        xmlStr=xmlStr.split("\r\n")[1];        log.info("转换后的参数："+xmlStr);        return xmlStr;    }}
