AOP and Spring.NET

Today I wrote a nice code using AOP and Spring.NET.I used IOC facilities of Spring.NET and it is really fantastic. Implementing some interfaces and a little bit of code you can have great and flexible code.

This is an example of interface that you must implement:

using System;
using System.Reflection;
using Actvalue.Data.Interfaces;
using My.JobProfiler.Entities;
using Spring.Aop;

namespace My.AOP
{
    public class CVLoggingAfterAdvice : IAfterReturningAdvice
    {
        public void AfterReturning(
           object returnValue, MethodInfo method, object[] args, object target)
        {
            EasyCV.Entities.CVStatus st;
            if (args.Length > 0)
                st = (EasyCV.Entities.CVStatus)args[0];
            else return;
            IUnitOfWork UoW = DataAccessProviderFactory.GetConversationUnitOfWork();
            CVHistory obj = new CVHistory();
            obj.CV = UoW.GetByKey<Actvalue.JobProfiler.Entities.CVCore>(st.cvst_cvcr_id);
            obj.Modified = DateTime.Now;
            obj.Status_Id = st.cvst_cvtypologicalId_State;
            obj.Type_Id = st.cvst_cvtypologicalId_Type;
            obj.User = "rew";
            UoW.RegisterNew(obj);

        }
    }
}
 

After running a method I logged everything there without change class (class that I call) that works. After in web.config I used IOC Spring facilities:

 <spring>
    <context>
      <resource uri="config://spring/objects" />
    </context>
    <objects xmlns="http://www.springframework.net">
      <description></description>

      <object id="afterAdvice" type="My.AOP.CVLoggingAfterAdvice, Actvalue.AOP" />
      <object id="throwsAdvice"  type="My.AOP.CVLoggingThrowsAdvice, Actvalue.AOP" />

      <object id="CVStatusChanged" type="Spring.Aop.Framework.ProxyFactoryObject">
        <property name="Target">
          <object type="My.DataAccessLayer.CVStatusDAL, My.DataAccessLayer" />
        </property>
        <property name="InterceptorNames">
          <list>
            <value>afterAdvice</value>
            <value>throwsAdvice</value>
          </list>
        </property>
      </object>
    </objects>
  </spring>

 
This is a little methos test for see if it works:

        [NUnit.Framework.Test()]
        public void CVHistoryTest1()
        {
            // Create AOP proxy using Spring.NET IoC container.
            IApplicationContext ctx = ContextRegistry.GetContext();
            ICVStatus command = (ICVStatus)ctx["CVStatusChanged"];
            My.Entities.CVStatus obj=new CVStatus();
            obj.cvst_cvcr_id = 23;
            obj.cvst_cvtypologicalId_State = 588;
            obj.cvst_cvtypologicalId_Type = 592;
            obj.cvst_dateinserted = DateTime.Now;
            obj.cvst_dateupdated = DateTime.Now;
            obj.cvst_profcatassigned = 12111;

            command.Update(obj);
            
        }

I used more times AOP with Spring.NET and it is a great framework for AOP too (for IOC maybe is the best). Maybe in future I will write an article about AOP in Spring.NET...
