SpringBoot项目引入Shiro时，出现错误 : java.lang.NoClassDefFoundError: org/springframework/core/lo

原因：

版本兼容问题。

 Application run failed

上面使用的是

    
        org.springframework.boot
        spring-boot-starter-parent
        2.2.26.RELEASE
         
    

版本太高，不兼容

使用低版本,注意版本是2.1.10！！！！

    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.10.RELEASE
