关于shiro错误分析：

错误提示：

我这是普通java工程，错误原因在于没有将SecurityManager设置到系统运行环境，这样静态资源SecurityUtils无法载进去，使用SecurityUtils.getSubject()的时候就会报错

添加如下代码即可

//创建SecurityManager工厂
        Factory<SecurityManager> factory=new IniSecurityManagerFactory("classpath:com/txr/resource/shiro-permission.ini");
        //创建SecurityManager
        SecurityManager securityManager=factory.getInstance();
        //将SecurityManager设置到系统运行环境
        SecurityUtils.setSecurityManager(securityManager);
