注：本人所用JSON为alibaba的json。至于效率相对一般json如何。各位自己baidu就知道了。运行需要相应jar包。

欢迎互相交流。效率至上哦。看到很多人居然遍历List**new 对象然后封装成JSON数据。实在多此一举。不管是new对象还是使用普通JSON效率上都是大打折扣。希望我这个精简代码可以帮到大家。互相学习。用的是alibaba的JSON。

必须要支持主动交流的朋友！

请问楼主需要导入那些jar包 特别是json方面的

json方面就一个alibaba的jar。

进qun交流，我的新群：1806431，欢迎你的加入。java开源struts1、struts2、spring、hibernate、ibatis等，另有ztree、json、jsp等网页技术。
