杭州家具网站建设方案whois域名查询

1、需求

对于Teach账号创建的数据，其他用户仅仅只有查询的权限，而不能修改和删除。并且部分接口只允许Teach账号访问

2、实现思路

在删除和修改时往往需要传递数据的id，进而可以通过id查询该数据是否由Teach账号创建。当然我们可以在每个删除和修改接口里面进行判断，但这样照成管控不够集中，并且不利于后续的修改。如果后续又要求对Admin账号创建的数据也做同样的管控，那需要修改的地方会很多。
因此可以通过Aop拦截删除、修改等接口，通过接口的参数中的查询id对应的数据是否由Teach账号创建。

3、实现Demo

}

4、可优化点

切入点表达式，可以改为自定义注解
