Einfaches Beispiel zu Remoting mit Springframework .Net

[Thomas Darimont]

Hallo,

hier mal ein einfaches Beispiel zu Remoting mit Springframework .Net. (Ein einfaches Beispiel zu konventionellem Remoting unter .Net findet man hier: http://www.tutorials.de/forum/net-w...66857-einfaches-beispiel-zu-net-remoting.html )
Hierbei haben wir zwei Projekte:
1) Server (beinhaltet die Service Implementierung und exportiert den Service als Server Activated Object (SAO))
2) Client (benutzt den Service über einen Remoting Proxy)

Die Springframework .Net Bibliotheken bekomment man von:
http://springframework.net/download.html

D:\stuff\.net\spring.net\1.1-M1\Spring.NET\bin\net\2.0\debug -> (der einfachheit halber alle assemblies Referenzieren)

Dokumentation zu Springframework.Net Remoting findet man hier:
file:///D:/stuff/.net/spring.net/1.1-M1/Spring.NET/doc/reference/html/remoting.html

Das Client Projekt hat einen Verweis auf das Server Projekt.

Unser Interface über den wir unseren Service Remote verfügbar machen wollen:

using System;
using System.Collections.Generic;
using System.Text;

namespace De.Tutorials.Training.Spring.Services
{
    public interface IBusinessService
    {
        string BusinessOperation(string argument);
    }
}

Unsere Service Implementierung:

using System;
using System.Collections.Generic;
using System.Text;

namespace De.Tutorials.Training.Spring.Services.Internal
{
    public class BusinessService : IBusinessService
    {
        

        public bool LoggingEnabled
        {
            get { return loggingEnabled; }
            set { loggingEnabled = value; }
        } private bool loggingEnabled;
    

        #region IBusinessService Member

        public string BusinessOperation(string argument)
        {
            if (LoggingEnabled)
            {
                Console.WriteLine("Executing business operation with: " + argument);
            }
            return "Upper: " + argument.ToUpper();
        }

        #endregion
    }
}

Unser Server:

using System;
using System.Collections.Generic;
using System.Text;
using Spring.Context;
using Spring.Context.Support;
using System.Runtime.Remoting;

namespace De.Tutorials.Training.Spring
{
    public class Server
    {
        static void Main(string[] args)
        {
            IApplicationContext applicationContext = ContextRegistry.GetContext();
            Console.WriteLine("Server started");
            Console.ReadLine();
        }
    }
}

Unsere App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <spring>
    <context name="spring.root">
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.net http://www.springframework.net/xsd/spring-objects.xsd">
      <object name="businessService" type="De.Tutorials.Training.Spring.Services.Internal.BusinessService"
      singleton="true">
        <property name="loggingEnabled" value="true"/>
      </object>

      <object name="saoBusinessService" type="Spring.Remoting.SaoExporter, Spring.Services">
        <property name="TargetName" value="businessService" />
        <property name="ServiceName" value="RemotedBusinessService" />
      </object>

      <object type="Spring.Remoting.RemotingConfigurer, Spring.Services">
        <property name="filename" value="Server.exe.config"/>
      </object>
      
    </objects>
  </spring>

  <system.runtime.remoting>
    <application>
      <channels>
        <channel ref="tcp" port="8005"  />
      </channels>
    </application>
  </system.runtime.remoting>
</configuration>

Unser Client:

using System;
using System.Collections.Generic;
using System.Text;
using Spring.Context;
using Spring.Context.Support;
using De.Tutorials.Training.Spring.Services;
using System.Threading;

namespace Client
{
    public class Program
    {
        static void Main(string[] args)
        {
            IApplicationContext applicationContext = ContextRegistry.GetContext();
            IBusinessService businessService = (IBusinessService)applicationContext.GetObject("businessService");
            for (int i = 0; i < 10; i++)
            {
                Console.WriteLine("Client got response: " + businessService.BusinessOperation("bubu"+DateTime.Now.Ticks));
                Thread.Sleep(1000);
            }
        }
    }
}

Unsere App.config (für den Client):

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="spring">
      <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
      <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
    </sectionGroup>
  </configSections>
  <spring>
    <context name="spring.root">
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.net http://www.springframework.net/xsd/spring-objects.xsd">
      <object id="businessService" type="Spring.Remoting.SaoFactoryObject, Spring.Services">
        <property name="ServiceInterface" value="De.Tutorials.Training.Spring.Services.IBusinessService, Server" />
        <property name="ServiceUrl" value="tcp://localhost:8005/RemotedBusinessService" />
      </object>
    </objects>
  </spring>
</configuration>

Ausgabe:
Server:
