版本说明

---

本文中使用的XStream版本为1.4.7:

<dependency><groupId>com.thoughtworks.xstream</groupId>        <artifactId>xstream</artifactId>        <version>1.4.7</version></dependency>

XSteam常用注解

---

• @XStreamAlias("message") 设置节点别名，用于类、字段。
• @XStreamAsAttribute 设置字段为属性，用于字段。
• @XStreamOmitField (反)序列化过程中忽略的字段，用于字段。
  
• @XStreamConverter(SingleValueCalendarConverter.class) 注入转换器(自定义转换器)，用于类、字段。
