Biwen.Settings 是一个简易的配置项管理模块,主要的作用就是可以校验并持久化配置项,比如将自己的配置存储到数据库中,JSON文件中等
使用上也是很简单,只需要在服务中注入配置,
比如我们有一个GithubSetting的配置项,我们只需要定义好对象然后注入到Service中即可:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | [Description("Github配置")]public class GithubSetting : ValidationSettingBase{ [Description("Github用户名")] public string? UserName { get; set; } = "vipwan"; [Description("Github仓库")] public string? Repository { get; set; } = "Biwen.Settings"; [Description("Github Token")] public string? Token { get; set; } = ""; public GithubSetting() { //验证规则 RuleFor(x => x.UserName).NotEmpty().Length(3, 128); RuleFor(x => x.Repository).NotNull().NotEmpty().Length(3, 128); RuleFor(x => x.Token).NotNull().NotEmpty().Length(3, 128); }} |
1 | @inject GithubSetting GithubSetting;//直接对象注入 |
尽管这样已经足够好用且便捷,但是对于习惯了使用IConfiguration和IOptions的朋友来说还是有些不习惯,其实实现对IConfiguration的支持还是很简单的,实现一下IConfigurationProvider即可,我们来动手实现一个名为BiwenSettingConfigurationProvider的Provider:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 | internal class Events{ /// <summary> /// Channel队列 /// </summary> public static readonly Channel ConfigrationChangedChannel = Channel.CreateUnbounded();}internal sealed class BiwenSettingConfigurationSource(bool autoRefresh = true) : IConfigurationSource{ public IConfigurationProvider Build(IConfigurationBuilder builder) => new BiwenSettingConfigurationProvider(autoRefresh);}internal class BiwenSettingConfigurationProvider : ConfigurationProvider, IDisposable, IAsyncDisposable{ public BiwenSettingConfigurationProvider(bool autoRefresh) { if (Settings.ServiceRegistration.ServiceProvider is null) { throw new BiwenException("必须首先注册Biwen.Setting模块,请调用:services.AddBiwenSettings()"); } if (autoRefresh) { StartAlertAsync(cts.Token); } } private CancellationTokenSource cts = new(); /// <summary> /// 使用Channel通知配置变更,如果有事件更新则重新加载 /// </summary> /// /// public Task StartAlertAsync(CancellationToken cancellationToken) { _ = Task.Run(async () => { while (!cancellationToken.IsCancellationRequested) { _ = await Events.ConfigrationChangedChannel.Reader.ReadAsync(cancellationToken); Load(); //通知配置变更 OnReload(); } }, cancellationToken); return Task.CompletedTask; } //从SettingManager中加载配置项 public override void Load() { Dictionary dics = []; using var scope = Settings.ServiceRegistration.ServiceProvider.CreateScope(); var settingManager = scope.ServiceProvider.GetRequiredService(); var settings = settingManager.GetAllSettings()!; foreach (var setting in settings) { if (setting.SettingContent is null) continue; if (JsonNode.Parse(setting.SettingContent) is not JsonObject json) continue; foreach (var item in json) { dics.TryAdd($"{setting.SettingName}:{item.Key}", item.Value?.ToString()); } } Data = dics; } public void Dispose() { cts.Cancel(); Events.ConfigrationChangedChannel.Writer.Complete(); } public ValueTask DisposeAsync() { cts.Cancel(); Events.ConfigrationChangedChannel.Writer.Complete(); return ValueTask.CompletedTask; }} |
内部通过Channel实现变更通知,
1 2 3 4 5 6 7 8 | internal class ConfigurationMediratorDoneHandler(ILogger logger) : IMediratorDoneHandler{ public Task OnPublishedAsync(T @event) where T : ISetting, new() { Events.ConfigrationChangedChannel.Writer.TryWrite((true, typeof(T).Name)); logger.LogInformation($"Setting Changed: {typeof(T).Name},并通知Configuration刷新!"); return Task.CompletedTask; }} |
然后老规矩我们扩展一下IServiceCollection:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | public static class ServiceRegistration { internal static IServiceCollection AddBiwenSettingConfiguration(this IServiceCollection services) { //ConfigurationMediratorDoneHandler services.AddSingleton(); return services; } /// <summary> /// 提供对IConfiguration,IOptions的支持 /// </summary> /// /// /// public static ConfigurationManager AddBiwenSettingConfiguration( this ConfigurationManager manager, IServiceCollection serviceDescriptors, bool autoRefresh = true) { var sp = Settings.ServiceRegistration.ServiceProvider ?? throw new BiwenException("必须首先注册Biwen.Setting模块,请调用:services.AddBiwenSettings()"); //添加订阅 if (autoRefresh) {serviceDescriptors.AddBiwenSettingConfiguration(); } IConfigurationBuilder configBuilder = manager; configBuilder.Add(new BiwenSettingConfigurationSource(autoRefresh)); var settings = ASS.InAllRequiredAssemblies.ThatInherit(typeof(ISetting)).Where(x => x.IsClass && !x.IsAbstract).ToList(); //注册ISetting settings.ForEach(x => { //IOptions DI manager?.GetSection(x.Name).Bind(GetSetting(x, sp)); }); return manager; } static object GetSetting(Type x, IServiceProvider sp) { var settingManager = sp.GetRequiredService(); var cache = sp.GetRequiredService(); //使用缓存避免重复反射 var md = cache.GetOrCreate($"GenericMethod_{x.FullName}", entry => { MethodInfo methodLoad = settingManager.GetType().GetMethod(nameof(settingManager.Get))!; MethodInfo generic = methodLoad.MakeGenericMethod(x); return generic; }); return md!.Invoke(settingManager, null)!; } } |
最后在启动时调用AddBiwenSettingConfiguration扩展即可
1 | builder.Configuration.AddBiwenSettingConfiguration(builder.Services, true); |
最后按下面的形式注册就可以了:
1 2 3 4 | @inject GithubSetting GithubSetting;//直接对象注入@inject IOptions IOP; //通过IOptions注入@inject IConfiguration Configuration;//IConfiguration... |
