            1.4.10
        

注解：

 @XStreamAlias("a")

 代码：

    public  T transferXMLToBean(Class clazz, String str) {
        XStream xstream = new XStream();
        xstream.processAnnotations(clazz);
        xstream.autodetectAnnotations(true);
        xstream.setupDefaultSecurity(xstream);
        xstream.allowTypes(new Class[]{clazz});
//或//  xstream.allowTypesByRegExp(new String[] {".*"});
        xstream.setClassLoader(clazz.getClassLoader());//这行是重点

        return (T)xstream.fromXML(str);
    }
