Detailed explanation of the conversion of xml and Java objects

1.xstream parsed message

XStreamComponent x = XStreamComponent.newInstance();
 x.processAnnotations(new Class[]{EquityExchangeDetail.class,PearTicketCustomerDTO.class,Date.class,Integer.class});
 EquityExchangeDetail ptd = (EquityExchangeDetail) x.fromXML(xml);

2.xstream encapsulated message

XStreamComponent xres = XStreamComponent.newInstance();
    xres.processAnnotations(new Class[]{TransResult.class});
 String result=xres.toXML(transResult);

3.Annotation:

@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. Method comparison

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. Parse the message

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
