幸福框架：可扩展的应用程序 “启动引导” 框架

news 来源：原创 2024/4/30 21:33:41

背景

应用程序引导经常要做如下这些事情：

- 动态加载DLL（或各种插件）。
- 注册IOC容器。
- 设置其他全局配置。

尤其以注册IOC容器的代码最烦人，看一个我昨天写的烦人代码：

 1 using System;
 2  using System.Collections.Generic;
 3  using System.Linq;
 4  using System.Text;
 5  using System.Threading.Tasks;
 6  using System.Threading;
 7  
 8  using Microsoft.Practices.ServiceLocation;
 9  using Microsoft.Practices.Unity;
10  
11  using Happy.Event;
12  using Happy.Event.Offline;
13  
14  namespace Happy.Event.Demo.Simple
15  {
16      class Program
17      {
18          static readonly string _QueueName = "Happy.Event.Demo.Simple";
19  
20          static void Main(string[] args)
21          {
22              InitUnity();
23  
24              var writeQueue = OfflineEventQueueFactory.CreateMSMQOfflineEventQueue(_QueueName);
25              EventPublisher.Current.AddService(writeQueue);
26  
27              EventPublisher.Current.Publish(new TestEvent());
28  
29              new Thread(() =>
30              {
31                  var readQueue = OfflineEventQueueFactory.CreateMSMQOfflineEventQueue(_QueueName);
32                  var offlineEventProcessor = new OfflineEventProcessor(readQueue);
33  
34                  offlineEventProcessor.Start();
35              })
36              .Start();
37  
38              Console.ReadLine();
39          }
40  
41          static void InitUnity()
42          {
43              var container = new UnityContainer();
44  
45              ServiceLocator.SetLocatorProvider(() => new UnityServiceLocator(container));
46  
47              container.RegisterType<ISyncEventSubscriber<TestEvent>, TestSyncEventSubscriber1>("TestSyncEventSubscriber1");
48              container.RegisterType<ISyncEventSubscriber<TestEvent>, TestSyncEventSubscriber2>("TestSyncEventSubscriber2");
49              container.RegisterType<IAsyncEventSubscriber<TestEvent>, TestAsyncEventSubscriber1>("TestAsyncEventSubscriber1");
50              container.RegisterType<IAsyncEventSubscriber<TestEvent>, TestAsyncEventSubscriber2>("TestAsyncEventSubscriber2");
51              container.RegisterType<IOfflineEventSubscriber<TestEvent>, TestOfflineEventSubscriber1>("TestOfflineEventSubscriber1");
52              container.RegisterType<IOfflineEventSubscriber<TestEvent>, TestOfflineEventSubscriber2>("TestOfflineEventSubscriber2");
53          }
54      }
55  }

是不是很糟糕，看着不爽。这也是我写这篇文章的目的。

新框架原理

约定胜于配置

用新框架重新昨天的配置代码

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 using System.Threading;
 7 
 8 using Happy.Bootstrap;
 9 using Happy.Event;
10 using Happy.Event.Offline;
11 
12 namespace Happy.Event.Demo.Simple
13 {
14     class Program
15     {
16         static readonly string _QueueName = "Happy.Event.Demo.Simple";
17 
18         static void Main(string[] args)
19         {
20             InitApp();
21 
22             InitOfflineEventProcessor();
23 
24             InitEventPublisher();
25 
26             EventPublisher.Current.Publish(new TestEvent());
27         }
28 
29         static void InitApp()
30         {
31             BootstrapService
32                 .Current
33                 .UseRegisterServiceByConventionPlug()
34                     .UseEventSubscriberRegister()
35                     .Done()
36                 .Start();
37         }
38 
39         private static void InitEventPublisher()
40         {
41             var writeQueue = OfflineEventQueueFactory.CreateMSMQOfflineEventQueue(_QueueName);
42             EventPublisher.Current.AddService(writeQueue);
43         }
44 
45         private static void InitOfflineEventProcessor()
46         {
47             new Thread(() =>
48             {
49                 var readQueue = OfflineEventQueueFactory.CreateMSMQOfflineEventQueue(_QueueName);
50                 var offlineEventProcessor = new OfflineEventProcessor(readQueue);
51 
52                 offlineEventProcessor.Start();
53             })
54             .Start();
55         }
56     }
57 }
