这几天在用xstream做转换的时候发现了类型不匹配的属性xStream会自动在节点加上class=xxxx,看着非常不爽
解决办法:

public class XMLUtil

{
    private static final XStream xStream = new XStream();

    // 将对象转为XML字符串
    public static <T> String toXML(T obj)

    {
        Class<?> cls = obj.getClass();
        xStream.alias(cls.getSimpleName().toLowerCase(),cls);
        xStream.aliasSystemAttribute(null,"class"); // 去掉 class 属性
        return xStream.toXML(obj);
    }

    // 将XML字符串转为对象
    @SuppressWarnings({"unchecked"})
    public static <T> T fromXML(String xml)

    {
        return (T) xStream.fromXML(xml);
    }
}
