Spring.Net Overview

Configure

• Add to References
  • Spring.Core.dll
• Add to App.config or Web.config

  <sectionGroup name="spring">
    <section name="context"
      type="Spring.Context.Support
              .ContextHandler,
      Spring.Core" />
      <section name="objects"
      type="Spring.Context.Support
              .DefaultSectionHandler,
    Spring.Core" />
  </sectionGroup>

• Define an object interface

  public interface ISimpleMessage
  {
  String Message { get; }
  }

• Do an implementation

  public class SimpleMessage  
    : ISimpleMessage{
    private String _message;
    public SimpleMessage(){}
    public SimpleMessage(String message)
    {
      _message = message;
    }
   
    public String Message
    {
      get { return _message; }
      set { _message = value; }
    }
  }

• Map objects in App.config

  <spring>
  <context>
    <resource uri="config://spring/objects" />
  </context>
  <objects xmlns=
    "http://www.springframework.net">
    <!-- Messages -->
    <object name="SimpleMessage"
      type="Test.Spring.SimpleMessage, 
      Test.Spring"
      singleton="false">
      <constructor-arg name="message"
      value="constructor-based injection." />
    </object>
    <object name="SimpleMessageByProperty"
      type="Test.Spring.SimpleMessage, 
        Test.Spring"
      singleton="false">
      <property name="Message" 
        value="property-based injection." />
    </object>
  </objects>
  </spring>

• Use

  using Spring.Context;
  using Spring.Context.Support;
   
  ...
   
  IApplicationContext ctx = 
    ContextRegistry.GetContext();
  ISimpleMessage smsg = (ISimpleMessage) 
    ctx.GetObject("SimpleMessage");
  label1.Text = smsg.Message;
  ...

• Constructor injection

  <object name="SimpleMessage"
    type="Test.Spring.SimpleMessage, 
    Test.Spring"
    singleton="false">
    <constructor-arg name="message"
    value="constructor-based injection." />
  </object>

• Property injection

  <object name="SimpleMessageByProperty"
    type="Test.Spring.SimpleMessage, 
      Test.Spring"
    singleton="false">
    <property name="Message" 
      value="property-based injection." />
  </object>

• IMessageSource
  • For retrieving localized resources
    • Text
    • Image
  • Add a resouce file called TestResource.resx
  • Add a resouce file called TestImages.resx
  • Add to App.config

  <object name="messageSource" 
     type="Spring.Context.Support
     .ResourceSetMessageSource, 
      Spring.Core">
    <property name="resourceManagers">
     <list>
      <value>Test.Spring.TestImages, 
       Test.Spring</value>
     <ref object="myResourceManager" />
      </list>
    </property>
  </object>
   
  <object name="myResourceManager" 
    type="Spring.Objects.Factory
     .Config.ResourceManagerFactoryObject, 
     Spring.Core">
    <property name="baseName" 
     value="Test.Spring.TestResource" />
    <property name="assemblyName" 
     value="Test.Spring" />
  </object>

  • Use

    // Default culture
    label1.Text = ctx.GetMessage("FirstName", 
      CultureInfo.CurrentCulture);
    //Display spanish
    CultureInfo spanish = new CultureInfo("es");
    label1.Text = 
      ctx.GetMessage("FirstName", spanish);
    // Get image
    pbxTest.Image = ctx.GetResourceObject(
      "Sunset") as Image;
