Spring.NET Installation and setup the first program

  

1. Download the file in blue box from website http://www.springsource.com/, then execute the exe file to install it

 

2. Create a sample porject called DataAccess in C# console program

3. Add C:\Program Files\Spring.NET 1.3.2\bin\net\2.0\release\Spring.Core.dll  (2.0 means framework 2)

The solution file is like

The code is like below

Program.cs

   1: using System;

   2: using System.Collections.Generic;

   3: using System.Text;

   4: using Spring.Context;

   5: using Spring.Context.Support; 

   6: namespace DataAccess

   7: {

   8:   class MainApp

   9:   { 

  10:     static void Main()

  11:     {

  12:       DataAccessObject daoCategories = new Categories();

  13:       daoCategories.Run();

  14:  

  15:       DataAccessObject daoProducts = new Products();

  16:       daoProducts.Run();

  17:  

  18:       IApplicationContext context = ContextRegistry.GetContext(); 

  19:       DataAccessObject DAO = (DataAccessObject)context.GetObject("DataAccessObject");

  20:       DAO.Run();

  21:  

  22:       // Wait for user

  23:       Console.ReadKey();

  24:     }

  25:   }

  26:  

  27:   abstract class DataAccessObject

  28:   {

  29:     protected string connectionString; 

  30:  

  31:     public virtual void Connect()

  32:     {

  33:         Console.WriteLine("Connect '" + connectionString + "'"); 

  34:     }

  35:  

  36:     public abstract void Select();

  37:     public abstract void Process();

  38:  

  39:     public virtual void Disconnect()

  40:     {

  41:         Console.WriteLine("Discount\r\n");

  42:     }

  43:  

  44:     // The 'Template Method'

  45:     public void Run()

  46:     {

  47:       Connect();

  48:       Select();

  49:       Process();

  50:       Disconnect();

  51:     }

  52:   }

  53:   

  54:   class Categories : DataAccessObject

  55:   {

  56:     public override void Select()

  57:     {

  58:         Console.WriteLine("Get Categories"); 

  59:     }

  60:  

  61:     public override void Process()

  62:     {

  63:         Console.WriteLine("Process Categories"); 

  64:     }

  65:   }

  66:   

  67:   class Products : DataAccessObject

  68:   {

  69:     public override void Select()

  70:     {

  71:         Console.WriteLine("Get Products"); 

  72:     }

  73:  

  74:     public override void Process()

  75:     {

  76:         Console.WriteLine("Process Products"); 

  77:     }

  78:   }

  79: } 

App.config

xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
    sectionGroup>
  configSections>
  <spring>
    <context>
      <resource uri="spring.xml.config"/>
    context> 
  spring>
configuration>

 

 

spring.xml.config

xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <object id="DataAccessObject" type="DataAccess.Products">
    <property name="connectionString" value="C:\db\northwind.mdb"/>
  object>
objects>

 

Running the application, the output is like

Now modify the spring.xml.config as below, only change “Products” to “Categories”

xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net">
  <object id="DataAccessObject" type="DataAccess.Categories">
    <property name="connectionString" value="C:\db\northwind.mdb"/>
  object>
objects>

 

The output will be changed to

See the red highlight, it has changed the program direction without recompile the exe.
