所以我正在使用rails3_acts_as_paranoidgem，并且在使用has_many:throughassociations控制范围时遇到了一些问题。例如#User.rbacts_as_paranoidhas_many:foldershas_many:files,:through=>:folders-#Folder.rbacts_as_paranoidbelongs_to:userhas_many:files,:dependent=>:destroy-#File.rbacts_as_paranoidbelongs_to:files现在让我们在users_controller.

我正在使用Jackson来解析我无法控制的JSON。JSON如下所示:{"status":"0""type":"type1""info":{//additionalfields}}我的类(class)是这样的publicclassResponse{privateStringstatus;privateStringtype;privateInfoinfo}我使用的Info的子类取决于type属性，所以我对info的映射是@JsonTypeInfo(use=JsonTypeInfo.Id.NAME,include=JsonTypeInfo.As.EXTERNAL_PROPERTY,prop
