JAVA實現map集合轉成XML格式
例如:
程式碼塊
import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.Map.Entry; import org.dom4j.Document; import org.dom4j.DocumentException; import org.dom4j.DocumentHelper; import org.dom4j.Element; import cn.sdk.util.StringUtil; public class XmlUtil { private static final String PREFIX_XML = "<xml>"; private static final String SUFFIX_XML = "</xml>"; private static final String PREFIX_CDATA = "<![CDATA["; private static final String SUFFIX_CDATA = "]]>"; /** * 轉化成xml, 單層無巢狀 * @param map * @param isAddCDATA * @return */ public static String mapToXml(Map<Object, Object> parm, boolean isAddCDATA) { StringBuffer strbuff = new StringBuffer(PREFIX_XML); if (null != parm) { for (Entry<Object, Object> entry : parm.entrySet()) { strbuff.append("<").append(entry.getKey()).append(">"); if (isAddCDATA) { strbuff.append(PREFIX_CDATA); if (null != entry.getValue()) { strbuff.append(entry.getValue()); } strbuff.append(SUFFIX_CDATA); } else { if (null != entry.getValue()) { strbuff.append(entry.getValue()); } } strbuff.append("</").append(entry.getKey()).append(">"); } } return strbuff.append(SUFFIX_XML).toString(); } /** * @description 將xml字串轉換成map * @param xml * @return Map */ public static Map<String, String> xml2Map(String xml) { Map<String, String> map = new HashMap<String, String>(); Document doc = null; try { doc = DocumentHelper.parseText(xml); // 將字串轉為XML Element rootElt = doc.getRootElement(); // 獲取根節點 @SuppressWarnings("unchecked") List<Element> list = rootElt.elements();// 獲取根節點下所有節點 for (Element element : list) { // 遍歷節點 map.put(element.getName(), element.getText()); // 節點的name為map的key,text為map的value } } catch (DocumentException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } return map; }
