I am using the Spring Frame Work .net to integrate the c# Application as follows.
Setting The Development Environment
1.1 Installing the NuGet Extension
Please follow the
NuGetInstall link to install the nuget extension for visual studio 2010.
1.2 Downloading the Pr-Requisiste Software Using Nuget Package Manager Console.
After Installing Nuget application, Create the HelloWorld console application in visual studio as follows.
1.2.1 File --> Project --> ConsoleApplication --> Enter application name is HelloWorld.
1.2.2
Open the Nuget Package Manager Console using Menu Tools --> Library
Package Manager --> Package Manager Console and It will open the
following screen.
1.2.3 Download the Spring Core Application using NuGet Package Manager Console.
Install-Package Spring.Core -Version 1.3.2
After Running the above command, the
Spring.Core dependencies are downloaded and as shown in the screen shot.
1.2.4 Download the Common.Logging.Log4Net using NuGet Package Manager Console.
Install-Package Common.Logging.Log4Net -Version 1.2.0
After Running the above command, the
Common.Logging.Log4Net dependencies are downloaded and as shown in the screen shot.
After
running above commands, all dependencies are added to your HelloWorld
Solution Folder --> Reference folder and it is shown below.
And also dll's are copied to your project solution folder --> Packages. The hierarchy as shown below.
Develop the Hello World Application
Create the Hello Package Folder
Create the
Hello Folder in the HelloWorld Solution Explore.
Create the Hello World Class
Create the following Class in the Hello Folder
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace HelloWorld.Hello
{
public class HelloWorld
{
public string GetMessage()
{
return "My First Spring Hello World Application";
}
}
}
Create the App.conf File
Right Click HelloWorld Solution Folder
--> Add --> New Item > Choose Application Configuration File
--> Click Add button and it will create the App.conf file.
Add the following Content to the App.conf file.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
</sectionGroup>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<common>
<logging>
<factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net">
<!-- choices are INLINE, FILE, FILE-WATCH, EXTERNAL-->
<!-- otherwise BasicConfigurer.Configure is used -->
<!-- log4net configuration file is specified with key configFile-->
<arg key="configType" value="INLINE" />
</factoryAdapter>
</logging>
</common>
<spring>
<context>
<!-- using embedded assembly configuration file
<resource uri="assembly://Spring.IocQuickStart.MovieFinder/Spring.IocQuickStart.MovieFinder/AppContext.xml"/>
-->
<!-- using section in App.config -->
<resource uri="config://spring/objects"/>
</context>
<objects xmlns="http://www.springframework.net" >
<description>An example that demonstrates simple IoC features.</description>
<object id="hello"
type="HelloWorld.Hello.HelloWorld, HelloWorld">
</object>
</objects>
</spring>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%-5level - %message%newline" />
</layout>
</appender>
<!-- Set default logging level to DEBUG -->
<root>
<level value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
</root>
<!-- Set logging for MovieFinder to DEBUG -->
<logger name="hello">
<level value="DEBUG" />
</logger>
<!-- Set logging for Spring to INFO.
Logger names in Spring correspond to the namespace -->
<logger name="Spring">
<level value="INFO" />
</logger>
</log4net>
</configuration>
Registering the Bean
I have highlighted the bold and italic font to register the Spring Bean in the App.Conf file As follows.
<object id="hello"
type="HelloWorld.Hello.HelloWorld, HelloWorld">
</object>
Id : Unique Id for your bean.
type: Hello World Class Name, and Assembly Name.
In our example Class Name is HelloWorld.Hello.HelloWorld and Assmbly Name is HelloWorld.
Running the Application
Getting the Spring Context
IApplicationContext context= ContextRegistry.GetContext();
Getting the registered bean
HelloWorld Hello = (HelloWorld)context.GetObject("hello");
Invoke the Hello WolrdBean GetMessage Method
Console.WriteLine (hello.GetMessage());
HelloWorld Client Class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Spring.Context;
using Spring.Context.Support;
using HelloWorld.Hello;
namespace HelloWorld
{
public class Program
{
static void Main(string[] args)
{
IApplicationContext context = null;
try
{
Console.WriteLine("Initializing the Context");
context = ContextRegistry.GetContext();
Console.WriteLine("Initializing the Context Successfully");
Console.WriteLine("Getting the HelloWorld Handle");
HelloWorld.Hello.HelloWorld hello = (HelloWorld.Hello.HelloWorld)context.GetObject("hello");
Console.WriteLine("Data Out put from spring method {0}", hello.GetMessage());
}
catch (Exception e)
{
Console.WriteLine(e);
}
finally
{
if (context != null)
{
context.Dispose();
}
}
}
}
}
Copy Dependencies DLL and XML Files to bin/debug folder
Visual
studio 2010 shouldn't copy internal dependencies to bin/debug folder.
Please go to the HelloWorld/Packages directory and copy the following
dependency files to bin/debug folder.
copy Common.Logging.Log4Net.1.2.0\lib\2.0\Common.Logging.Log4Net.dll ..\HelloWorld\bin\Debug
copy log4net.1.2.10\lib\2.0\log4net* ..\HelloWorld\bin\Debug
Execute Application
Go
to the HelloWorld Project Directory --> bin --> Debug Directory
and run the HelloWorld.exe and it will display the following output
Initializing the Context
INFO - ApplicationContext Refresh: Completed
Initializing the Context Successfully
Getting the HelloWorld Handle
Data Out put from spring method My First Spring Hello World Application
