java XML解析成Map
1.需要解析的文件.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <request> 3 <realName>test</realName> 4 <identityNumber>411525152242417185276</identityNumber> 5 <phone>1314456788</phone> 6 <user> 7 <value>1444444</value> 8 <name>12334</name> 9 <aa> 10 <hehe>222222</hehe> 11 </aa> 12 <age>23</age> 13 </user> 14 </request>
2.工具包
1 package com.ynet.utils; 2 3 import org.dom4j.Document; 4 import org.dom4j.Element; 5 6 import java.util.*; 7 8 /** 9 * Created by Arya on 2017/11/3. 10 */ 11 public class XmlUtils { 12 public static Map<String, Object> Dom2Map(Document doc) { 13 Map<String, Object> map = new HashMap<String, Object>(); 14 if (doc == null) 15 return map; 16 Element root = doc.getRootElement(); 17 for (Iterator iterator = root.elementIterator(); iterator.hasNext(); ) { 18 Element e = (Element) iterator.next(); 19 List list = e.elements(); 20 if (list.size() > 0) { 21 map.put(e.getName(), Dom2Map(e)); 22 } else 23 map.put(e.getName(), e.getText()); 24 } 25 return map; 26 } 27 28 29 public static Map Dom2Map(Element e) { 30 Map map = new HashMap(); 31 List list = e.elements(); 32 if (list.size() > 0) { 33 for (int i = 0; i < list.size(); i++) { 34 Element iter = (Element) list.get(i); 35 List mapList = new ArrayList(); 36 37 if (iter.elements().size() > 0) { 38 Map m = Dom2Map(iter); 39 if (map.get(iter.getName()) != null) { 40 Object obj = map.get(iter.getName()); 41 if (!obj.getClass().getName().equals("java.util.ArrayList")) { 42 mapList = new ArrayList(); 43 mapList.add(obj); 44 mapList.add(m); 45 } 46 if (obj.getClass().getName().equals("java.util.ArrayList")) { 47 mapList = (List) obj; 48 mapList.add(m); 49 } 50 map.put(iter.getName(), mapList); 51 } else 52 map.put(iter.getName(), m); 53 } else { 54 if (map.get(iter.getName()) != null) { 55 Object obj = map.get(iter.getName()); 56 if (!obj.getClass().getName().equals("java.util.ArrayList")) { 57 mapList = new ArrayList(); 58 mapList.add(obj); 59 mapList.add(iter.getText()); 60 } 61 if (obj.getClass().getName().equals("java.util.ArrayList")) { 62 mapList = (List) obj; 63 mapList.add(iter.getText()); 64 } 65 map.put(iter.getName(), mapList); 66 } else 67 map.put(iter.getName(), iter.getText()); 68 } 69 } 70 } else 71 map.put(e.getName(), e.getText()); 72 return map; 73 } 74 }
3.控制器
1 package com.ynet.controller; 2 3 4 import com.ynet.utils.XmlUtils; 5 import org.dom4j.Document; 6 import org.dom4j.DocumentHelper; 7 import org.springframework.boot.autoconfigure.EnableAutoConfiguration; 8 import org.springframework.web.bind.annotation.RequestMapping; 9 import org.springframework.web.bind.annotation.RestController; 10 11 import org.dom4j.DocumentException; 12 13 import java.io.FileInputStream; 14 import java.io.IOException; 15 import java.util.Map; 16 17 /** 18 * Created by Arya on 2017/11/3. 19 */ 20 @RestController 21 @EnableAutoConfiguration 22 public class XmlDemoController { 23 @RequestMapping(value="/xmlDemo") 24 public Map<String, Object> xmlDocumentFile(){ 25 Document doc = null; 26 try { 27 FileInputStream fis = new FileInputStream("F:\\myweb\\gateway\\gateway2\\src\\main\\resources\\customer.xml"); 28 byte[] b = new byte[fis.available()]; 29 fis.read(b); 30 String str = new String(b); 31 doc = DocumentHelper.parseText(str); 32 } catch (IOException e) { 33 e.printStackTrace(); 34 } catch (DocumentException e) { 35 e.printStackTrace(); 36 } 37 38 return XmlUtils.Dom2Map(doc); 39 } 40 }
