Asp.net MVC + EF + Spring.Net 项目实践（二）

这一篇主要介绍数据库和entity framework集成

1. 先创建数据库，很简单的几张表，但也涉及了一些主外键关系、联合主键等，关系图如下（DB脚本在最后）

　　

2. 打开VS，现在建立Model实体，在Repository层右键，选择“新建项目”，添加“数据”-“ADO.NET 实体数据类型”，名称改为“SMSContext”，也可以后期再修改

　　

3. 点击“添加”选择“来自数据库的 Code First”选项，什么？没有此选项？呵呵~~~（请下载eftool http://www.microsoft.com/en-us/download/details.aspx?id=40762）

　　

4. 点击“下一步”，选择“Microsoft SQL Server”，之后选择数据库

　　

5. 按上面的配置，将App.Config文件先单独存储，后面我们会把连接字符串放到WEB项目中，再把这个文件删掉的

　　选择要生成Model的表，点击“完成”

　　

6. VS会自动引入EntityFramework和另的一些dll，生成SMSContex.cs还有对应的Grade, Score, Student, Subject类，也就是咱们需要的Model，如下图所示　　　　　　

7. 删除没用的Class1.cs，再创建一个单元测试项目来验证一下（记得要把app.config复制一份放到测试项目里），发现能取出内容，OK。
