Abp介绍
学习了一段时间的Abp,领略了一下前辈的架构.总结还是SOLID,降低耦合性.
虽然从架构上说甚至不依赖于DI框架,但实际上在基础框架中还是有一定的必须依赖Castle Windsor.
Abp依靠IOC和AOP实现了大量的自动化.
其中Module设计,是Abp的核心.
Abp源码分析
Abp的入口:AbpBootstrapper.Initialize()
此方法中做了各种配置的注册及初始化.
最重要的是AbpModuleManager的初始化.
在这个初始化代码中
先查询出所有的module,根据依赖关系排序后.并保证AbpKernelModule为第一.
然后初始化module,所有module依次调用PreInitialize、Initialize、PostInitialize
代码实现
定义AbpModule
public class AbpModule
{
public virtual void PreInitialize() { }
public virtual void Initialize() { }
public virtual void PostInitialize() { }
}
定义2个module
public class ApplicationModule : AbpModule
{
public override void PreInitialize()
{
Console.WriteLine("ApplicationModule's PreInitialize is called");
} public override void Initialize()
{
Console.WriteLine("ApplicationModule's Initialize is called");
} public override void PostInitialize()
{
Console.WriteLine("ApplicationModule's PostInitialize is called");
}
} public class CoreModule : AbpModule
{
public override void PreInitialize()
{
Console.WriteLine("CoreModule's PreInitialize is called");
} public override void Initialize()
{
Console.WriteLine("CoreModule's Initialize is called");
} public override void PostInitialize()
{
Console.WriteLine("CoreModule's PostInitialize is called");
}
}
定义IoCManager
public class IocManager
{
public static IocManager Instance { get; private set; } public IWindsorContainer IocContainer { get; private set; } static IocManager()
{
Instance = new IocManager();
} public IocManager()
{
IocContainer = new WindsorContainer();
//Register self!
IocContainer.Register(
Component.For<IocManager>().UsingFactoryMethod(() => this)
);
}
}
实现AbpBootstrapper
public class AbpBootstrapper
{
public IocManager IocManager { get; private set; }
public AbpBootstrapper()
{
IocManager = IocManager.Instance;
}
public virtual void Initialize()
{
InitializeModules();
}
private void InitializeModules()
{
var types = Assembly.GetExecutingAssembly().GetTypes();
var moduleTypes = new List<Type>();
var modules = new List<AbpModule>();
foreach (var type in types)
{
if (typeof(AbpModule).IsAssignableFrom(type))
{
moduleTypes.Add(type);
IocManager.IocContainer.Register(Component.For(type));
}
}
foreach (var module in moduleTypes)
{
var obj = IocManager.IocContainer.Resolve(module) as AbpModule;
modules.Add(obj);
}
modules.ForEach(x => x.PreInitialize());
modules.ForEach(x => x.Initialize());
modules.ForEach(x => x.PostInitialize());
}
}
执行
class Program
{
static void Main(string[] args)
{
var booter = new AbpBootstrapper();
booter.Initialize(); Console.ReadKey();
}
}
Abp原理如上,只是在本例中并未做dependency排序处理.
在Abp中的排序依赖ListExtensions类对List的扩展方法实现的.
