dom4j maven依賴
<!-- https://mvnrepository.com/artifact/dom4j/dom4j -->
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>xml轉換為map的方法原始碼
/** * * @param xml 要轉換的xml字串 * @param charset 字元編碼 * @return 轉換成map後返回結果 * @throws UnsupportedEncodingException * @throws DocumentException */ public static Map<String, String> xmlToMap(String xml, String charset) throws UnsupportedEncodingException, DocumentException{ Map<String, String> respMap = new HashMap<String, String>(); SAXReader reader = new SAXReader(); Document doc = reader.read(new ByteArrayInputStream(xml.getBytes(charset))); Element root = doc.getRootElement(); xmlToMap(root, respMap); return respMap; } public static Map<String, String> xmlToMap(Element tmpElement, Map<String, String> respMap){ ArrayList<String> strings = new ArrayList<String>(); for (String s:strings ) { } if (tmpElement.isTextOnly()) { respMap.put(tmpElement.getName(), tmpElement.getText()); return respMap; } @SuppressWarnings("unchecked") Iterator<Element> eItor = tmpElement.elementIterator(); while (eItor.hasNext()) { Element element = eItor.next(); xmlToMap(element, respMap); } return respMap; }
注意導包不要搞錯
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;測試資料

測試之後得出的map呼叫toString並列印輸出，得到的結果
{to=George, body=Don't forget the meeting!, from=John, heading=Reminder}
