Simple graduation design with asp.net MVC3

A friend wants to make a graduation project and ask me to help him develop a simple library management system. I have nothing to do at night, so I am ready to help him develop a simple one. Because it is a graduation project, I plan to use a technology that is rarely used in my work to develop it. I also want to train myself. So I chose Entityframework, spring.net, asp.net MVC and other technologies for development. The following is the project structure of my project:

 

Common is a public class that stores public classes that are not related to the business, and also contains extension methods in this class library.

Domain is the Domain logic layer, which stores Domain objects.

DTO is the data transmission Object layer, which is mainly used to transmit data objects. In MVC, the data transmission objects from Controller to View or View to Controller are also placed here, And ViewData is not used.

The Filter layer is used to control permissions and operation log records.

Model is a Model level, Entityframework object, and some enumeration objects are placed in this layer.

Repository is the database persistence layer.

 

EntityFrameworkHeper code:

 

1 using System;
2 using System. Collections. Generic;
3 using System. Linq;
4 using System. Text;
5 using Com. Romi. YangXiaoDong. Model;
6 using Com. Romi. YangXiaoDong. IRepository;
7 using System. Threading;
8
9 namespace Com. Romi. YangXiaoDong. Repository
10 {
11 /// <summary>
12 // persistence base class
13 /// </summary>
14 public class BaseRepository
15 {
16 private static ThreadLocal <BookManageEntities> threadLocal = new ThreadLocal <BookManageEntities> ();
17 # region IBaseQuery Member
18 /// <summary>
19 // open
20 /// </summary>
21 /// <returns> </returns>
22 public BookManageEntities GetSession ()
23 {
24 BookManageEntities session = (BookManageEntities) threadLocal. Value;
25 if (session = null)
26 {
27 session = new BookManageEntities ();
28 threadLocal. Value = session;
29}
30 return session;
31}
32 /// <summary>
33 // close
34 /// </summary>
35 public void CloseSession ()
36 {
37 BookManageEntities session = (BookManageEntities) threadLocal. Value;
38 if (session! = Null)
39 {
40 session. Dispose ();
41}
42}
43 # endregion
44}
45}

 

The above code is modeled after the help class of Hibernate in java. If you have any questions, I would be very grateful to you.

This article mainly introduces the basic structure of the trainer project. The next article will briefly introduce the simple application of EntityFramework in this project.

It is the source code, but it simply implements the user management function.
