构建ASP.NET MVC4+EF5+EasyUI+Unity2.x注入的后台管理系统（23）-权限管理系统-角色组模块

系列目录

距离上次发布22讲已经有少许日子了,真是太抱歉,最近年关项目比较急,时间太紧,没有时间发布.请大家见谅

接下来我们的目标是

1. 角色组管理
2. 角色组权限设置
3. 用户管理
4. 把角色组授权给用户
5. 给用户分配角色组

所以最少我们还要讲多5讲才能结束这个管理系统，经过之前的样例程序，我们很熟悉这个套路了，如果你很喜欢这个系列，你可以为这种重复性的动作写一个简单的代码生成器，或者一套强大的T4模版，其实这2个我都有，而且也是刚写的，以后系统完善了，给发布出来。

是不是还可以呢，哈哈，T4我也写了一套，但毕竟还是没有winfrom来得方便。

接下来我们在之前做好的模块管理，在22讲中，添加角色组管理的记录和操作码，如图

目前我是需要添加这么多个操作码。回头就机械性的创建DAL层，BLL层，Model层，还有注入

我们注重的是效果，看下

由于我们的用户管理还没做，分配还不能做，所以就先给个空的值吧。

我们能够这么机械性全靠我们的架构，才能这么清晰的分析问题。

做了这么久不知道大家有没有发现，层层扣层层，异常捕获，异常记录，日志记录，反转控制，系统的可维护性非常的高，一目了然，这也是发布文章这么久，没人质疑这个架构的所在之处（我们是不是应该自豪一下）

上面的图已经好了，关于记录，那必须是要有新增修改功能了，这个留给大家自己动手做做，因为这节是没有好讲的，这是为了下一节的，权限设置做铺垫而已。

谢谢大家
