使用xStream对xml进行反序列化转为JavaBean

在前面已经介绍使用xStream包处理null值的问题，现在我们一起讨论一下对于使用xStream进行反序列化的问题。
这里我们使用的xml模板为：

<ShippingOrder xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/DataExchange.Utility.BussinessObject">

我们需要四个类，分别为SendXML、Consignee、Consignor和Goods，这里我给出SendXML的源码如下：

public class SendXML {

	private String billId;// 托运单号

	private String labelId;// 票签号
	
	private String isRouteRecord;//记录类型，0为线路员记录单，1为托运单

	private String branchName;// 营业网点名称

	private String stationName;// 受理站

	private String sendStationName;// 发送站点

	private String transferName;// 中转站编号

	private String endStationName;// 到达站点

	private String chargeType;// 收费模式
	
	private String procedureCharge;// 手续费

	private String packageBillId;// 打包托运单号

	private String agencyPrice;// 代收货款
	
	private String prepayPrice;// 代垫货款

	private String totalCharge;// 总金额
	
	private String totalCount;// 总数量
	
	private String totalWeight;// 总重量
	
	private String isInsurance;//是否保价

	private Consignee consignee;// 收获方信息

	private Consignor consignor;// 装货方信息
	
	private String consigneeCardNO;// 收获人身份证

	private String consigneeSignName;// 收获人签名

	private Date travelTime;// 运输时间

	private Date acceptTime;// 受理时间

	private Date checkTime;// 签发时间

	private Date limitTime;// 到货时限
	
	private String billingPersonName;//开单人姓名
	
	private String routePersonName;//线路员
	
	private String remark;//备注
	
	private String route;//终点站（使用）
	
	private String consigneeName;//收货人姓名
	
	private String consignorName;//发货人姓名
	
	private List<Goods> goodsInfomations;//货物信息
        
        //setter、getter

之前看了很多其他的介绍没有使用转换器的，但这里我必须需要写转换器实现，否则无法得到结果。
在这里我写了一个类实现Converter接口，如：

        //这个是反序列化是实现的方法
        @Override
	public Object unmarshal(HierarchicalStreamReader reader,
			UnmarshallingContext context) {
		
		SendXML sendXML = new SendXML();
		
		while(reader.hasMoreChildren()){
			reader.moveDown();
			String node = reader.getNodeName();
			if (node.indexOf("Time")!=-1) {
				SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.0");
				Date date = null;
				try {
					date = sdf.parse(reader.getValue());
				} catch (ParseException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
				String temp = node.substring(0, 1).toUpperCase()+node.substring(1);
				Class[] classes = new Class[1];
				classes[0] = Date.class;
				try {
					Method m = SendXML.class.getMethod("set"+temp, classes);
					m.invoke(sendXML, date);
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}else if ("consigneeInfomation".equals(node)) {
				Consignee cgee = new Consignee();
				while(reader.hasMoreChildren()){
					reader.moveDown();
					String node2 = reader.getNodeName();
					if ("requestedUnloadedDateTime".equals(reader.getNodeName())) {
						SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.0");
						Date date = null;
						try {
							date = sdf.parse(reader.getValue());
						} catch (ParseException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						}
						cgee.setRequestedUnloadedDateTime(date);
					}else {
						String temp = node2.substring(0, 1).toUpperCase()+node2.substring(1);
						try {
							Class[] classes = new Class[1];
							classes[0] = String.class;
							Method method = Consignee.class.getMethod("set"+temp, classes);
							method.invoke(cgee, reader.getValue());
						} catch (Exception e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						}
					}
					reader.moveUp();
				}
				
				sendXML.setConsignee(cgee);
			}else if("consignorInfomation".equals(node)){
				Consignor cgor = (Consignor)context.convertAnother(sendXML, Consignor.class);
				sendXML.setConsignor(cgor);
			}else if ("goodsInfomations".equals(node)) {
				List<Goods> list = new ArrayList<Goods>();
				while(reader.hasMoreChildren()){
					reader.moveDown();
					Goods goods = (Goods)context.convertAnother(sendXML, Goods.class);
					list.add(goods);
					reader.moveUp();
				}
				sendXML.setGoodsInfomations(list);
			}else {
				String temp = node.substring(0, 1).toUpperCase()+node.substring(1);
				try {
					Class[] classes = new Class[1];
					classes[0] = String.class;
					Method method = SendXML.class.getMethod("set"+temp, classes);
					method.invoke(sendXML, reader.getValue());
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
			reader.moveUp();
		}
		return sendXML;
	}

在使用到XStream时，需要注册这个转换器，如：

File xmlModel = new java.io.File(filePath);
		
		FileInputStream in  = new FileInputStream(xmlModel);
		
		XStream xStream = new XStream(new DomDriver());
		xStream.alias("ShippingOrder", SendXML.class);
		
		xStream.registerConverter(new ShippingConverter());
		SendXML sendXML = (SendXML)xStream.fromXML(in);

现在基本上就已经满足要求了，但是效率不高。
