基础环境：依赖
org.springframework.boot spring-boot-starter-parent2.2.1.RELEASE
org.apache.shiro shiro-spring-boot-starter1.4.0
如果不是前后端分离，要实现页面级的权限控制，则加入以下依赖就可以使用shiro的权限标签了（记得在html头部加上相应约束：

补充：SpringBoot配置Shiro时踩坑
在SpringBoot2.0整合shiro时使用@EnableAutoConfiguration的时候需要对config文件进行扫描，即使用@ComponentScan对配置进行扫描。
或者直接使用@SpringBootApplication,但是这种方法会将主方法目录下的所有package都进行扫描影响项目效率。
Authentication failed for token submission [org.apache.shiro.authc.UsernamePasswordToken - zxc, rememberMe=false]. Possible unexpected error? (Typical or expected login exceptions should extend from AuthenticationException
当出现此异常时，一般情况是用户名密码不匹配，或者是在配置对应的Realm时出现空值导致匹配失败。
以上为个人经验，希望能给大家一个参考，也希望大家多多支持考高分网。如有错误或未考虑完全的地方，望不吝赐教。
