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

using System;
using System.Collections.Generic;
using System.Text;
using Spring.Context;
using Spring.Context.Support;
namespace DataAccess
{
  class MainApp
  {
    static void Main()
    {
      DataAccessObject daoCategories = new Categories();
      daoCategories.Run();

      DataAccessObject daoProducts = new Products();
      daoProducts.Run();

      IApplicationContext context = ContextRegistry.GetContext();
      DataAccessObject DAO = (DataAccessObject)context.GetObject("DataAccessObject");
      DAO.Run();

      // Wait for user
      Console.ReadKey();
    }
  }

  abstract class DataAccessObject
  {
    protected string connectionString;

    public virtual void Connect()
    {
        Console.WriteLine("Connect '" + connectionString + "'");
    }

    public abstract void Select();
    public abstract void Process();

    public virtual void Disconnect()
    {
        Console.WriteLine("Discount\r\n");
    }

    // The 'Template Method'
    public void Run()
    {
      Connect();
      Select();
      Process();
      Disconnect();
    }
  }

  class Categories : DataAccessObject
  {
    public override void Select()
    {
        Console.WriteLine("Get Categories");
    }

    public override void Process()
    {
        Console.WriteLine("Process Categories");
    }
  }

  class Products : DataAccessObject
  {
    public override void Select()
    {
        Console.WriteLine("Get Products");
    }

    public override void Process()
    {
        Console.WriteLine("Process Products");
    }
  }
}

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.
