java实现Xml与json之间的相互转换操作示例

package exercise.xml;import net.sf.json.JSON;import net.sf.json.JSONSerializer;import net.sf.json.xml.XMLSerializer;import org.jdom.Document;public class XmlExercise {  /**   * 将xml字符串<STRONG>转换</STRONG>为JSON字符串   *   * @param xmlString   *      xml字符串   * @return JSON<STRONG>对象</STRONG>   */  public static String xml2json(String xmlString) {    XMLSerializer xmlSerializer = new XMLSerializer();    JSON json = xmlSerializer.read(xmlString);    return json.toString(1);  }  /**   * 将xmlDocument<STRONG>转换</STRONG>为JSON<STRONG>对象</STRONG>   *   * @param xmlDocument   *      XML Document   * @return JSON<STRONG>对象</STRONG>   */  public static String xml2json(Document xmlDocument) {    return xml2json(xmlDocument.toString());  }  /**   * JSON(数组)字符串<STRONG>转换</STRONG>成XML字符串   *   * @param jsonString   * @return   */  public static String json2xml(String jsonString) {    XMLSerializer xmlSerializer = new XMLSerializer();    return xmlSerializer.write(JSONSerializer.toJSON(jsonString));    // return xmlSerializer.write(JSONArray.fromObject(jsonString));//这种方式只支持JSON数组  }}

package exercise.xml;import net.sf.json.JSONArray;import net.sf.json.JSONObject;public class XmlTest extends XmlExercise {  public static void main(String[] args) {    JSONObject jsonObject = new JSONObject();    jsonObject.put("username", "horizon");    JSONArray jsonArray = new JSONArray();    JSONObject dataJson = new JSONObject();    jsonArray.add(jsonObject);    //jsonArray.add(jsonObject);    dataJson.put("data", jsonArray);    System.out.println(dataJson.toString());    String xml = json2xml(dataJson.toString());    System.out.println("xml:" + xml);    String str = xml2json(xml);    System.out.println("to_json" + str);  }}
