xml与Java对象的转换详解

xml与Java对象的转换详解

1.xstream解析报文

									XStreamComponent x = XStreamComponent.newInstance();

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

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

2.xstream封装报文

									XStreamComponent xres = XStreamComponent.newInstance();

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

									 String result=xres.toXML(transResult);

3.注解：

									@XStreamAlias("customerInfo")  //报文中<customerInfo>节点对应类名“PearTicketCustomerDTO”

									public class PearTicketCustomerDTO {

									@XStreamAlias("idno")   //报文中<idno>节点对应类属性“idno”

									 private String idno;

									@XStreamOmitField

									private Long ticketId;  //报文中无<ticketId>节点 ，解析时忽略类属性ticketId

4.方法比较

1 2	`x.processAnnotations（new` `Class[]{PearTicketDTO.class}）：读取类名注解` `x.alias(new` `Class[]{PearTicketDTO.class})：不读取类名注解`

5.解析报文

									x.alias("Equities", List.class);--把报文节点<Equities> 转化为List对象

									x.alias("Equity", Equity.class);--把报文节点<Equity> 转化为Equity类对象

									List<Equity> equities = (List<Equity>) x.fromXML(xml);--开始转化
