SpringBoot之----了解Shiro安全框架整合Mybatis和thymeleaf，实现授权登陆认证
这里我做一个流程图帮助大家理解Shiro安全框架整合Mybatis和thymeleaf，实现授权登陆认证的过程，大家先了解，然后看代码，看完代码再看流程图。
1.了解完那我们先看项目结构：
项目结构：
数据库截图：
2.我们再看整个项目的代码：

3.运行结果：
点击登陆：
那么输入我们数据库设计好的账号：wt 密码：123456 点击提交：
不难看出，这里只显示了add，说明某些用户获取的权限和看到界面就是给过滤过的，点击add就能看见我们写好给规定用户看的了：
那么我们换一个账号密码呢？账号：xian_yu 密码 123456
当然我们也只能看见update界面的东西：
这时候我们再去返回首页就能看见首页变成我们的update了：
