XStream异常com.thoughtworks.xstream.security.ForbiddenClassException

在使用XStream解析的过程中遇到com.thoughtworks.xstream.security.ForbiddenClassException异常的问题，解决方式：

xStream = new XStream();
//尽量限制所需的最低权限 这条语句解决该问题
xStream.addPermission(AnyTypePermission.ANY);

//对象设置默认安全防护 
//会导致com.thoughtworks.xstream.security.ForbiddenClassException
//xStream.setupDefaultSecurity(xStream);
//对类开启注解
xStream.processAnnotations(FaultInfo.class);
