xml與Java對象的轉換詳解

1.xstream解析報文

									XStreamComponent x = XStreamComponent.newInstance();

									 x.processAnnotations(new Class[]{EquityExchangeDetail.class,PearTicketCustomerDTO.class,Date.class,Integer.class});

									 EquityExchangeDetail ptd = (EquityExchangeDetail) x.fromXML(xml);

2.xstream封裝報文

									XStreamComponent xres = XStreamComponent.newInstance();

									    xres.processAnnotations(new Class[]{TransResult.class});

									 String result=xres.toXML(transResult);

3.注解：

									@XStreamAlias("customerInfo")  //報文中<customerInfo>節點對應類名“PearTicketCustomerDTO”

									public class PearTicketCustomerDTO {

									@XStreamAlias("idno")   //報文中<idno>節點對應類屬性“idno”

									 private String idno;

									@XStreamOmitField

									private Long ticketId;  //報文中無<ticketId>節點 ，解析時忽略類屬性ticketId

4.方法比較

1 2	`x.processAnnotations（new` `Class[]{PearTicketDTO.class}）：讀取類名注解` `x.alias(new` `Class[]{PearTicketDTO.class})：不讀取類名注解`

5.解析報文

									x.alias("Equities", List.class);--把報文節點<Equities> 轉化為List對象

									x.alias("Equity", Equity.class);--把報文節點<Equity> 轉化為Equity類對象

									List<Equity> equities = (List<Equity>) x.fromXML(xml);--開始轉化
