Abp.VNext 用.NET Core Console 项目介绍Abp (一)

首先需要 Nuget 上下载 Volo.Abp.Core Volo.Abp.Autofac

项目结构

AbpConsole 项目 Program 代码引用了 Volo.Abp.Autofac

 1 using AbpConsole;
 2 using Microsoft.Extensions.DependencyInjection;
 3 using Microsoft.Extensions.Hosting;
 4 using Volo.Abp.Modularity.PlugIns;
 5 
 6 static IHostBuilder CreateHostBuilder(string[] args) =>
 7          Host.CreateDefaultBuilder(args)
 8              .ConfigureAppConfiguration((context, config) =>
 9              {
10                  //setup your additional configuration sources
11              })
12              .UseAutofac()
13              .ConfigureServices((hostContext, services) =>
14              {
15                  services.AddApplication<ConsoleModule>(options =>
16                  {
17                      // 1、加载插件
18                     options.PlugInSources.AddFolder(@"D:\学习\Plugln");
19                  });
20              });
21 CreateHostBuilder(args).RunConsoleAsync().Wait();

ConsoleHostedService 代码

 1 using AbpConsoleAppCommon;
 2 using AbpConsoleInteface;
 3 using Microsoft.Extensions.Hosting;
 4 using System;
 5 using System.Collections.Generic;
 6 using System.Linq;
 7 using System.Text;
 8 using System.Threading.Tasks;
 9 
10 namespace AbpConsole
11 {
12     public class ConsoleHostedService : IHostedService
13     {
14 
15         //没有 传统 构造函数注入
16         // private readonly HelloWorldService _helloWorldService;
17         //public ConsoleHostedService(HelloWorldService helloWorldService)
18         //{
19         //    this._helloWorldService = helloWorldService;
20         //}
21 
22 
23         /// <summary>
24         /// 利用 abp 的autofac 进行属性依赖注入
25         /// </summary>
26         public HelloWorldService _helloWorldService { get; set; }
27 
28         public CommonService CommonService { get; set; }
29         //这是插件
30         public IPluginService Plugln { get; set; }
31         public Task StartAsync(CancellationToken cancellationToken)
32         {
33             this._helloWorldService.Helloworld();
34             this.CommonService.Show();
35             Plugln.Plugin();
36             return Task.CompletedTask;
37         }
38 
39         public Task StopAsync(CancellationToken cancellationToken)
40         {
41             throw new NotImplementedException();
42         }
43     }
44 }

ConsoleModule 代码

 1 using AbpConsoleAppCommon;
 2 using Microsoft.Extensions.DependencyInjection;
 3 using System;
 4 using System.Collections.Generic;
 5 using System.Linq;
 6 using System.Text;
 7 using System.Threading.Tasks;
 8 using Volo.Abp.Autofac;
 9 using Volo.Abp.DependencyInjection;
10 using Volo.Abp.Modularity;
11 
12 namespace AbpConsole
13 {
14     [DependsOn(typeof(AbpAutofacModule),typeof(CommonModule))]
15     public class ConsoleModule : AbpModule
16     {
17         public override void ConfigureServices(ServiceConfigurationContext context)
18         {
19             // 1、IOC注册自定义类
20             System.Console.WriteLine("加载ConsoleModule模块");
21             //context.Services.AddSingleton<HelloWorldService>();
22             context.Services.AddHostedService<ConsoleHostedService>();
23         }
24     }
25 }

HelloWorldService 代码

 1 using Microsoft.Extensions.DependencyInjection;
 2 using System;
 3 using System.Collections.Generic;
 4 using System.Linq;
 5 using System.Text;
 6 using System.Threading.Tasks;
 7 using Volo.Abp.DependencyInjection;
 8 
 9 namespace AbpConsole
10 {
11     [Dependency(ServiceLifetime.Transient)]
12     public class HelloWorldService//: ITransientDependency
13     {
14         public void Helloworld()
15         {
16             Console.WriteLine("你好世界");
17         }
18     }
19 }

这里主要是特性

[DependsOn(typeof(AbpAutofacModule),typeof(CommonModule))] 对Module的标注 这里面是 是typeof 属性加载所以 Autofac需要在第一位置 要不然依赖
注入会有问题
[Dependency(ServiceLifetime.Transient)] 对 HelloWorldService 标注 有对生命周期 的标注
下面代码主要是 Abp 引用其他项目

 1 using Microsoft.Extensions.DependencyInjection;
 2 using System;
 3 using System.Collections.Generic;
 4 using System.Linq;
 5 using System.Text;
 6 using System.Threading.Tasks;
 7 using Volo.Abp.Modularity;
 8 
 9 namespace AbpConsoleAppCommon
10 {
11     public class CommonModule:AbpModule
12     {
13         public override void ConfigureServices(ServiceConfigurationContext context)
14         {
15             // base.ConfigureServices(context);    
16             // context.Services.AddHostedService<CommonService>();
17             System.Console.WriteLine("加载CommonModule模块");
18         }
19     }
20 }

 1 using Microsoft.Extensions.DependencyInjection;
 2 using System;
 3 using System.Collections.Generic;
 4 using System.Linq;
 5 using System.Text;
 6 using System.Threading.Tasks;
 7 using Volo.Abp.DependencyInjection;
 8 
 9 namespace AbpConsoleAppCommon
10 {
11 
12     [Dependency(ServiceLifetime.Scoped)]
13     public class CommonService
14     {
15         public void Show()
16         {
17             Console.WriteLine("我是common");
18         }
19     }
20 }

引用Common项目

设置依赖设置

使用插件

上层不能直接依赖插件，如果直接依赖插件就违反开闭原则，需要依赖接口

重点说明接口实现类名称是有约定的，一般去掉 I 就是接口实现类要不然加载插件会出现注入报错的情况

PluginService : IPluginService

 1 using AbpConsoleInteface;
 2 using Microsoft.Extensions.DependencyInjection;
 3 using System;
 4 using System.Collections.Generic;
 5 using System.Linq;
 6 using System.Text;
 7 using System.Threading.Tasks;
 8 using Volo.Abp.DependencyInjection;
 9 namespace AbpConsole.Plugln
10 {
11     [Dependency(ServiceLifetime.Transient)]
12     public class PluginService : IPluginService
13     {
14         public void Plugin()
15         {
16             Console.WriteLine("我是插件");
17         }
18     }
19 }

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 using Volo.Abp.Modularity;
 7 
 8 namespace AbpConsole.Plugln
 9 {
10     /// <summary>
11     /// 插件模块
12     /// </summary>
13     public class Plugin : AbpModule
14     {
15         public override void ConfigureServices(ServiceConfigurationContext context)
16         {
17             System.Console.WriteLine("加载插件模块...........");
18         }
19     }
20 }

然后编译，将编译后的DLL文件放置到文件夹里，然后引用

 .ConfigureServices((hostContext, services) =>
              {
                  services.AddApplication<ConsoleModule>(options =>
                  {
                      // 1、加载插件
                     options.PlugInSources.AddFolder(@"D:\学习\Plugln");
                  });
              });

 1 // See https://aka.ms/new-console-template for more information
 2 
 3 
 4 using AbpConsole;
 5 using Microsoft.Extensions.DependencyInjection;
 6 using Microsoft.Extensions.Hosting;
 7 using Volo.Abp.Modularity.PlugIns;
 8 
 9 static IHostBuilder CreateHostBuilder(string[] args) =>
10          Host.CreateDefaultBuilder(args)
11              .ConfigureAppConfiguration((context, config) =>
12              {
13                  //setup your additional configuration sources
14              })
15              .UseAutofac()
16              .ConfigureServices((hostContext, services) =>
17              {
18                  services.AddApplication<ConsoleModule>(options =>
19                  {
20                      // 1、加载插件
21                     options.PlugInSources.AddFolder(@"D:\学习\Plugln");
22                  });
23              });
24 CreateHostBuilder(args).RunConsoleAsync().Wait();
25 
26 Console.WriteLine("Hello, World!");

掉用直接写接口依赖注入了
