1.pom依赖
<dependency> <groupId>org.jdom</groupId> <artifactId>jdom</artifactId> <version>2.0.2</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.39</version> </dependency>
2.代码
1 public class Xml2JsonUtil { 2 3 /** 4 * 转换一个xml格式的字符串到json格式 5 * 6 * @param xml 7 * xml格式的字符串 8 * @return 成功返回json 格式的字符串;失败反回null 9 */ 10 public static String xml2JSON(String xml) { 11 JSONObject obj = new JSONObject(); 12 try { 13 InputStream is = new ByteArrayInputStream(xml.getBytes("utf-8")); 14 SAXBuilder sb = new SAXBuilder(); 15 Document doc = sb.build(is); 16 Element root = doc.getRootElement(); 17 obj.put(root.getName(), iterateElement(root)); 18 return obj.toString(); 19 } catch (Exception e) { 20 e.printStackTrace(); 21 return null; 22 } 23 } 24 25 /** 26 * 转换一个xml格式的字符串到json格式 27 * 28 * @param file 29 * java.io.File实例是一个有效的xml文件 30 * @return 成功反回json 格式的字符串;失败反回null 31 */ 32 public static String xml2JSON(File file) { 33 JSONObject obj = new JSONObject(); 34 try { 35 SAXBuilder sb = new SAXBuilder(); 36 Document doc = sb.build(file); 37 Element root = doc.getRootElement(); 38 obj.put(root.getName(), iterateElement(root)); 39 return obj.toString(); 40 } catch (Exception e) { 41 e.printStackTrace(); 42 return null; 43 } 44 } 45 46 /** 47 * 一个迭代方法 48 * 49 * @param element 50 * : org.jdom.Element 51 * @return java.util.Map 实例 52 */ 53 @SuppressWarnings({ "rawtypes", "unchecked" }) 54 private static Map iterateElement(Element element) { 55 List jiedian = element.getChildren(); 56 Element et = null; 57 Map obj = new HashMap(); 58 List list = null; 59 for (int i = 0; i < jiedian.size(); i++) { 60 list = new LinkedList(); 61 et = (Element) jiedian.get(i); 62 if (et.getTextTrim().equals("")) { 63 if (et.getChildren().size() == 0) 64 continue; 65 if (obj.containsKey(et.getName())) { 66 list = (List) obj.get(et.getName()); 67 } 68 list.add(iterateElement(et)); 69 obj.put(et.getName(), list); 70 } else { 71 if (obj.containsKey(et.getName())) { 72 list = (List) obj.get(et.getName()); 73 } 74 list.add(et.getTextTrim()); 75 obj.put(et.getName(), list); 76 } 77 } 78 return obj; 79 } 80 81 // 测试 82 public static void main(String[] args) { 83 String xml = "<xml><version><![CDATA[2.0]]></version><charset><![CDATA[UTF-8]]></charset><status><![CDATA[400]]></status><message><![CDATA[Require POST method]]></message></xml>"; 84 System.out.println(Xml2JsonUtil.xml2JSON(xml)); 85 } 86 }
3.运行结果(手动格式化了的)
{ "xml":{ "charset":[ "UTF-8" ], "message":[ "Require POST method" ], "version":[ "2.0" ], "status":[ "400" ] } }
