SpringMVC+ZTree实现树形菜单权限配置的方法

2021-03-11 14:06Javahih Java教程

本篇文章主要介绍了SpringMVC+ZTree实现树形菜单权限配置的方法,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧

计划在开源项目里加入权限配置的功能,打算加入ztree实现树形结构。

team的github开源项目链接:https://github.com/u014427391/jeeplatform 欢迎star(收藏)

ztree 是一个依靠 jquery 实现的多功能 “树插件”。优异的性能、灵活的配置、多种功能的组合是 ztree 最大优点。
