public static byte[] callMapToXML(Map map) {logger.info("将Map转成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("将Map转成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 + ">");}}}}

待转化的多层级map代码：

public static void main(String[] args) {Map<String, Object> dataMap = new LinkedHashMap<String, Object>(); //默认dataMap.put("rtnCode", "02");dataMap.put("rtnMsg", "查询失败");dataMap.put("idWltCloudDistrict", "专区id");Map<String, Object> bizMap = new LinkedHashMap<String, Object>();bizMap.put("serviceId", "serviceId001");bizMap.put("data", dataMap);//data节点是一个mapMap<String, Object> objMap = new LinkedHashMap<String, Object>();objMap.put("idWltCloudDistrict", "专区id");objMap.put("districtName", "专区名称");objMap.put("validateDateStart", "专区有效期开始");objMap.put("validateDateEnd", "专区有效期结束");objMap.put("status", "专区状态(00-待发布;01-销售中; 02-已下架;)");objMap.put("partnerId", "合作伙伴id");objMap.put("channelId", "渠道id");objMap.put("areaId", "商圈专区id");dataMap.putAll(objMap); //List<Map<String, Object>> prodKindList1 = new ArrayList<Map<String, Object>>();for(int i=1;i<=2;i++){// 第二层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", "类目ID");prodKindObj2.put("prodKindName", "类目名称");prodKindObj2.put("prodKindIdx", "类目序号");Map<String, Object> prodKind2 = new LinkedHashMap<String, Object>();prodKind2.put("prodKind", prodKindObj2);prodKindList2.add(prodKind2);}//第一层Map<String, Object> prodKindOjb1 = new LinkedHashMap<String, Object>();prodKindOjb1.put("idWltCloudProdKind", "类目ID");prodKindOjb1.put("prodKindName", "类目名称");prodKindOjb1.put("prodKindIdx", "类目序号");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);}

转化后效果：

<?xml version="1.0" encoding="utf-8"?><bizdata>    <serviceId>serviceId001</serviceId>    <data>        <rtnCode>02</rtnCode>        <rtnMsg>查询失败</rtnMsg>        <idWltCloudDistrict>专区id</idWltCloudDistrict>        <districtName>专区名称</districtName>        <validateDateStart>专区有效期开始</validateDateStart>        <validateDateEnd>专区有效期结束</validateDateEnd>        <status>专区状态(00-待发布;01-销售中; 02-已下架;)</status>        <partnerId>合作伙伴id</partnerId>        <channelId>渠道id</channelId>        <areaId>商圈专区id</areaId>        <prodKindList>            <prodKind>                <idWltCloudProdKind>类目ID</idWltCloudProdKind>                <prodKindName>类目名称</prodKindName>                <prodKindIdx>类目序号</prodKindIdx>                <prodKindList>                    <prodKind>                        <idWltCloudProdKind>类目ID</idWltCloudProdKind>                        <prodKindName>类目名称</prodKindName>                        <prodKindIdx>类目序号</prodKindIdx>                    </prodKind>                    <prodKind>                        <idWltCloudProdKind>类目ID</idWltCloudProdKind>                        <prodKindName>类目名称</prodKindName>                        <prodKindIdx>类目序号</prodKindIdx>                    </prodKind>                </prodKindList>            </prodKind>            <prodKind>                <idWltCloudProdKind>类目ID</idWltCloudProdKind>                <prodKindName>类目名称</prodKindName>                <prodKindIdx>类目序号</prodKindIdx>                <prodKindList>                    <prodKind>                        <idWltCloudProdKind>类目ID</idWltCloudProdKind>                        <prodKindName>类目名称</prodKindName>                        <prodKindIdx>类目序号</prodKindIdx>                    </prodKind>                    <prodKind>                        <idWltCloudProdKind>类目ID</idWltCloudProdKind>                        <prodKindName>类目名称</prodKindName>                        <prodKindIdx>类目序号</prodKindIdx>                    </prodKind>                </prodKindList>            </prodKind>        </prodKindList>    </data></bizdata>
