篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了asp.net mvc+web api+easyui相关的知识,希望对你有一定的参考价值。
前奏:第一次写博客,记录一下学习和开发的过程。
现在写的是一个后台管理系统,有基本的权限功能,其他功能都可以扩展。用到的技术是 asp.net mvc5,web api 2,entityframework,autofac,easyui等。
先来上个解决方案的图:
01-ZY.Web.MVC:是页面的展示,由于用了web api 所以在mvc里面没有做数据的操作。mvc里面主要有权限的判断,controller里面也没有太多的逻辑处理。
02-ZY.Web.Api:这里用到了web api。web api的好处是可以多平台调用,前后端可以分别开发,很好的分离了前后端的开发工作。
03-ZY.Identity:这里面主要是权限的判断,用到了asp.net identity。
04-ZY.Core:这个是项目的核心类库,包含了autofac,缓存,仓储接口,实体基类,扩展方法等,后续会详细的讲讲。
05-ZY.Repositories.EntityFramework:这个就是EntityFramework仓储的实现。
06-ZY.Model:这个就是实体类库。
在看一下运行的效果图片:
1:账号管理界面
2:编辑管理员 角色是多角色。
3:管理员选中角色,多角色选择,查找带回控件
4.设置菜单权限界面
5.角色管理 角色管理是在行内编辑
6.设置角色权限
7.菜单管理
8.设置菜单需要的按钮权限
再贴一些代码吧:
仓储接口

关于Repository的具体实现思路,博客园里面有很多文章了,这里就不详细说明了。
IUnitOfWork 考虑到可能会执行单独的存储过程,所以在UnitOfWork里面加了对存储过程的支持
using System; using System.Data; using System.Threading.Tasks; namespace ZY.Core.Repositories { /// <summary> /// 业务单元操作接口 /// </summary> public interface IUnitOfWork: IDependency, IDisposable { /// <summary> /// 提交 /// </summary> /// <returns></returns> void Commit(); /// <summary> /// 异步提交 /// </summary> /// <returns></returns> Task CommitAsync(); /// <summary> /// 同步 /// </summary> /// <param name="sql"></param> /// <param name="parameters"></param> /// <returns></returns> int ExecuteSqlCommand(string sql, params object[] parameters); /// <summary> /// 异步执行SQL语句 /// </summary> /// <param name="sql"></param> /// <param name="parameters"></param> /// <returns></returns> Task<int> ExecuteSqlCommandAsync(string sql, params object[] parameters); /// <summary> /// 执行存储过程 /// </summary> /// <param name="storedProcName">存储过程名称</param> /// <returns></returns> DataSet QueryProcedure(string storedProcName); /// <summary> /// 执行存储过程 带参数 /// </summary> /// <param name="storedProcName">存储过程名称</param> /// <param name="parameters">参数</param> /// <returns></returns> DataSet QueryProcedure(string storedProcName, IDataParameter[] parameters); /// <summary> /// 执行存储过程 /// </summary> /// <param name="storedProcName">存储过程名称</param> /// <param name="parameters">参数</param> /// <returns>存储过程返回值</returns> int RunProcedure(string storedProcName, IDataParameter[] parameters); /// <summary> /// 执行存储过程 /// </summary> /// <param name="storedProcName">存储过程名称</param> /// <param name="parameters">参数</param> /// <returns></returns> int RunProcedure(string storedProcName); } }
UnitOfWork的具体实现
