基于ABP的模块化、插件化设计，Abp底层框架提供便捷的方法集成每个Module，开发人员可以将自定义的功能以模块的形式集成到ABP中。
模块：
插件：
Configuration：
模块及插件的加载路线：
1. 扩展的HttpApplication对象（在Abp.Web项目中AbpWebApplication<TStartupModule> : HttpApplication）中有AbpBootstrapper成员
AbpWebApplication的Application_Start方法：
protected virtual void Application_Start(object sender, EventArgs e)
{
ThreadCultureSanitizer.Sanitize();
AbpBootstrapper.Initialize();
_webLocalizationConfiguration = AbpBootstrapper.IocManager.Resolve<IAbpWebLocalizationConfiguration>();
}
项目的Global文件中
public class MvcApplication : AbpWebApplication<HKWEBWebModule>
{
protected override void Application_Start(object sender, EventArgs e)
{
AbpBootstrapper.IocManager.IocContainer.AddFacility<LoggingFacility>(
f => f.UseAbpLog4Net().WithConfig("log4net.config")
);
//添加插件
AbpBootstrapper.PlugInSources.AddFolder(@"C:\MyPlugIns");
AbpBootstrapper.PlugInSources.AddTypeList(typeof(MyPlugInModule));
base.Application_Start(sender, e);
}
}
AbpBootstrapper的Initialize方法
public virtual void Initialize()
{
//实例化_logger
ResolveLogger();
try
{
//把Bootstrapper类自身加到容器里
RegisterBootstrapper();
IocManager.IocContainer.Install(new CoreInstaller());
//将附加的插件加入队列
IocManager.Resolve<PlugInManager>().PlugInSources.AddRange(PlugInSources);
//StartupConfiguration.Modules,Settings,ServiceReplaceActions等核心配置
IocManager.Resolve<StartupConfiguration>().Initialize();
_moduleManager = IocManager.Resolve<ModuleManager>();
//加载所有Module
_moduleManager.Initialize(StartupModule);
//对这些Module排序，之后依次执行所有模块的PreInitialize，Initialize，PostInitialize
_moduleManager.StartModules();
}
catch (Exception ex)
{
_logger.Fatal(ex.ToString(), ex);
throw;
}
}
模块管理器的初始化操作会加载所有依赖的模块，并通过模块类型上的Dependon属性确定它们的注册顺序，同时也会加载AbpBootstrapper.PlugInSources中添加的插件，插件的添加 目前提供了两种实现。
AbpBootstrapper的Dispose方法，倒序释放各模块中加载的资源
public virtual void Dispose()
{
if (IsDisposed)
{
return;
}
IsDisposed = true;
//倒序执行所有模块的Shutdown方法
_moduleManager?.ShutdownModules();
}
以Abp.Web模块为例，每个自定义模块都会提供一个由AbpModule衍生的类型，模块管理器就是遍历所有被应用的程序集，从中找到每一个包含AbpModule类型的视为一个个模块。然后在依据DependsOn对这些Module排序，之后依次执行所有模块的PreInitialize，Initialize，PostInitialize（3个foreach）。
[DependsOn(typeof(AbpWebCommonModule))]
public class AbpWebModule : AbpModule
{
/// <inheritdoc/>
public override void PreInitialize()
{
IocManager.Register<IAbpAntiForgeryWebConfiguration, AbpAntiForgeryWebConfiguration>();
IocManager.Register<IAbpWebLocalizationConfiguration, AbpWebLocalizationConfiguration>();
IocManager.Register<IAbpWebModuleConfiguration, AbpWebModuleConfiguration>();
Configuration.ReplaceService<IPrincipalAccessor, HttpContextPrincipalAccessor>(DependencyLifeStyle.Transient);
Configuration.ReplaceService<IClientInfoProvider, WebAuditInfoProvider>(DependencyLifeStyle.Transient);
AddIgnoredTypes();
}
/// <inheritdoc/>
public override void Initialize()
{
IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
}
//……
}
一个扩展方法用于添加配置信息，configurations.AbpConfiguration就是IAbpStartupConfiguration
public static class AbpWebConfigurationExtensions
{
/// <summary>
/// Used to configure ABP Web module.
/// </summary>
public static IAbpWebModuleConfiguration AbpWeb(this IModuleConfigurations configurations)
{
return configurations.AbpConfiguration.Get<IAbpWebModuleConfiguration>();
}
}
internal class AbpStartupConfiguration : DictionaryBasedConfig, IAbpStartupConfiguration
{
/// <summary>
/// Reference to the IocManager.
/// </summary>
public IIocManager IocManager { get; }
/// <summary>
/// Used to configure modules.
/// Modules can write extension methods to <see cref="ModuleConfigurations"/> to add module specific configurations.
/// </summary>
public IModuleConfigurations Modules { get; private set; }
public T Get<T>()
{
return GetOrCreate(typeof(T).FullName, () => IocManager.Resolve<T>());
}
//……
}
public class DictionaryBasedConfig : IDictionaryBasedConfig
{
/// <summary>
/// Dictionary of custom configuration.
/// </summary>
protected Dictionary<string, object> CustomSettings { get; private set; }
/// <summary>
/// Gets a configuration object with given name.
/// </summary>
public T GetOrCreate<T>(string name, Func<T> creator)
{
var value = Get(name);
if (value == null)
{
value = creator();
Set(name, value);
}
return (T) value;
}
//……
}
