public static byte[] callMapToXML(Map map) { logger.info("將Map轉成Xml, Map：" + map.toString()); StringBuffer sb = new StringBuffer(); sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?><bizdata>"); mapToXMLTest2(map, sb); sb.append("</bizdata>"); logger.info("將Map轉成Xml, Xml：" + sb.toString()); try { return sb.toString().getBytes("UTF-8"); } catch (Exception e) { logger.error(e); } return null; } private static void mapToXMLTest2(Map map, StringBuffer sb) { Set set = map.keySet(); for (Iterator it = set.iterator(); it.hasNext();) { String key = (String) it.next(); Object value = map.get(key); if (null == value) value = ""; if (value.getClass().getName().equals("java.util.ArrayList")) { ArrayList list = (ArrayList) map.get(key); sb.append("<" + key + ">"); for (int i = 0; i < list.size(); i++) { HashMap hm = (HashMap) list.get(i); mapToXMLTest2(hm, sb); } sb.append("</" + key + ">"); } else { if (value instanceof HashMap) { sb.append("<" + key + ">"); mapToXMLTest2((HashMap) value, sb); sb.append("</" + key + ">"); } else { sb.append("<" + key + ">" + value + "</" + key + ">"); } } } }
待轉化的多層級map程式碼：
public static void main(String[] args) { Map<String, Object> dataMap = new LinkedHashMap<String, Object>(); //預設 dataMap.put("rtnCode", "02"); dataMap.put("rtnMsg", "查詢失敗"); dataMap.put("idWltCloudDistrict", "專區id"); Map<String, Object> bizMap = new LinkedHashMap<String, Object>(); bizMap.put("serviceId", "serviceId001"); bizMap.put("data", dataMap);//data節點是一個map Map<String, Object> objMap = new LinkedHashMap<String, Object>(); objMap.put("idWltCloudDistrict", "專區id"); objMap.put("districtName", "專區名稱"); objMap.put("validateDateStart", "專區有效期開始"); objMap.put("validateDateEnd", "專區有效期結束"); objMap.put("status", "專區狀態(00-待發布;01-銷售中; 02-已下架;)"); objMap.put("partnerId", "合作伙伴id"); objMap.put("channelId", "渠道id"); objMap.put("areaId", "商圈專區id"); dataMap.putAll(objMap); // List<Map<String, Object>> prodKindList1 = new ArrayList<Map<String, Object>>(); for(int i=1;i<=2;i++){ // 第二層 List<Map<String, Object>> prodKindList2 = new ArrayList<Map<String, Object>>(); for(int j=1;j<=2;j++){ Map<String, Object> prodKindObj2 = new LinkedHashMap<String, Object>(); prodKindObj2.put("idWltCloudProdKind", "類目ID"); prodKindObj2.put("prodKindName", "類目名稱"); prodKindObj2.put("prodKindIdx", "類目序號"); Map<String, Object> prodKind2 = new LinkedHashMap<String, Object>(); prodKind2.put("prodKind", prodKindObj2); prodKindList2.add(prodKind2); } //第一層 Map<String, Object> prodKindOjb1 = new LinkedHashMap<String, Object>(); prodKindOjb1.put("idWltCloudProdKind", "類目ID"); prodKindOjb1.put("prodKindName", "類目名稱"); prodKindOjb1.put("prodKindIdx", "類目序號"); prodKindOjb1.put("prodKindList", prodKindList2); Map<String, Object> prodKind1 = new LinkedHashMap<String, Object>(); prodKind1.put("prodKind", prodKindOjb1); prodKindList1.add(prodKind1); } dataMap.put("prodKindList", prodKindList1); XmlCommonUtil.callMapToXML(bizMap); }
轉化後效果：
<?xml version="1.0" encoding="utf-8"?> <bizdata> <serviceId>serviceId001</serviceId> <data> <rtnCode>02</rtnCode> <rtnMsg>查詢失敗</rtnMsg> <idWltCloudDistrict>專區id</idWltCloudDistrict> <districtName>專區名稱</districtName> <validateDateStart>專區有效期開始</validateDateStart> <validateDateEnd>專區有效期結束</validateDateEnd> <status>專區狀態(00-待發布;01-銷售中; 02-已下架;)</status> <partnerId>合作伙伴id</partnerId> <channelId>渠道id</channelId> <areaId>商圈專區id</areaId> <prodKindList> <prodKind> <idWltCloudProdKind>類目ID</idWltCloudProdKind> <prodKindName>類目名稱</prodKindName> <prodKindIdx>類目序號</prodKindIdx> <prodKindList> <prodKind> <idWltCloudProdKind>類目ID</idWltCloudProdKind> <prodKindName>類目名稱</prodKindName> <prodKindIdx>類目序號</prodKindIdx> </prodKind> <prodKind> <idWltCloudProdKind>類目ID</idWltCloudProdKind> <prodKindName>類目名稱</prodKindName> <prodKindIdx>類目序號</prodKindIdx> </prodKind> </prodKindList> </prodKind> <prodKind> <idWltCloudProdKind>類目ID</idWltCloudProdKind> <prodKindName>類目名稱</prodKindName> <prodKindIdx>類目序號</prodKindIdx> <prodKindList> <prodKind> <idWltCloudProdKind>類目ID</idWltCloudProdKind> <prodKindName>類目名稱</prodKindName> <prodKindIdx>類目序號</prodKindIdx> </prodKind> <prodKind> <idWltCloudProdKind>類目ID</idWltCloudProdKind> <prodKindName>類目名稱</prodKindName> <prodKindIdx>類目序號</prodKindIdx> </prodKind> </prodKindList> </prodKind> </prodKindList> </data> </bizdata>
