每天学点Shiro-添加角色管理

protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

        System.out.println("=========>MyRealm doGetAuthorizationInfo");
        Set<String> set = new HashSet<>() ;
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(set) ;
        set.add("user") ;
        if("admin".equals(principalCollection.getPrimaryPrincipal())){
            set.add("admin") ;
        }
        return authorizationInfo;
    }
