class mytest {

    private String name;

    private String xb;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getXb() {
        return xb;
    }

    public void setXb(String xb) {
        this.xb = xb;
    }
}
 XStream 的编码:
    本身并没有实现编码，必须依靠java.io.Writer来实现输出编码的转换。参考上例代码
XStream 的常用方法
    xstream.omitField(mytest.class, "name");               定义某一个属性的值不进行xml序列化。
    xstream.alias("cat", Cat.class);
    xstream.aliasField("age", Cat.class, "mAge");        对某一个类和类的属性进行别名定义。
    xstream.useAttributeFor(String.class);                     对所有String类型的字段定义为属性tag显示
    xstream.useAttributeFor("name".String.class);       对所有String类型的字段名成为name 定义为属性tag显示
