Biwen.Settings 2.2.4

Biwen.Settings

Biwen.Settings介绍

解决程序配置项重复引用的问题,比如我们有一个GitHubSetting配置项, 我们可以在任意地方注入GitHubSetting,系统会自动将配置项注入到我们的业务代码中,并且可以在系统中动态修改配置项, 修改后会自动持久化到存储中,并通知集群的订阅子节点Setting配置项变更事件,清空缓存并重新加载持久层的最新项 案例项目:BiwenSettingsMutiNodeTest

当前仓储可以是一个抽象的概念,可以任意横向实现.比如使用多个数据库负载,或者多个Redis等.只要能保证数据一致性即可

基础案例

• 一个简单例子 比如我有一个Web站点,这个Web站点有很多的负载,以及一一些小程序后台服务 ,
• 这些独立的程序(或者裂变或者使用代理转发的微服务), 都使用同一个 WX账号收账,那么这些站点或者后台服务都可以是这个WX账号配置的消费节点,
• 这些节点可以配置一个或者多个作为主节点,当任意一个主节点修改配置项时,主动通知其他子节点更新配置,并且清空配置的缓存服务并重新加载Store!

NuGet 包

• dotnet add package Biwen.Settings

开发环境

• Windows 10
• Rider 2022 / Visual Studio 2022 / Visual Studio Code
• .NET 8.0

运行环境

• .NET 8.0

使用方式

[* 示例项目]

Easy to Use

Step 1

1.1 使用EntityFrameworkCore的方式

• implements IBiwenSettingsDbContext

public class MyDbContext : DbContext, IBiwenSettingsDbContext
{
    public MyDbContext(DbContextOptions<MyDbContext> options)
        : base(options)
    {
    }

    public DbSet<Setting> Settings { get; set; }

    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        //根据情况自定义表名
        builder.Entity<Setting>(b =>
        {
            b.ToTable("Settings");
        });
        //可以根据自己的情况约束存储列
        //builder.Entity<Setting>().HasKey(x => x.SettingName);
        //builder.Entity<Setting>().Property(x => x.SettingName).HasMaxLength(500);
    }
}

1.1.1 Migration

• Add a new Entity Framework Core migration to save your changes

dotnet ef migrations add biwenSettings
dotnet ef database update

1.2 使用自定义SettingManager

• 直接跳入step 2.2

step 2

• 2.1 如果使用Biwen.Settings提供的EF仓储,必须注入DBContext

builder.Services.AddDbContext<MyDbContext>(options =>
{
    //根据您的情况使用任意EFCore支持的数据库
    //当前使用内存数据库作为演示.生产环境务必修改!
    options.UseInMemoryDatabase("BiwenSettings");
});

• 2.2 如果使用自定义仓储,请实现ISettingManager并修改AddBiwenSettings()

options.UseSettingManager<T,V>()

step 3

• AddBiwenSettings & UseBiwenSettings

builder.Services.AddBiwenSettings(options =>
  {
//ProjectId : 项目标识 用于区分不同的项目,比如:日志系统,文件系统;或者环境,比如:开发环境,测试环境,生产环境
#if DEBUG
    options.ProjectId = $"Biwen.Settings.TestWebUI-{"Development"}";
#endif
#if !DEBUG
    options.ProjectId = $"Biwen.Settings.TestWebUI-{"Production"}";
#endif
//自定义布局
options.Layout = "~/Views/Shared/_Layout.cshtml";
options.Title = "Biwen.Settings";
//路由地址 ,http://..../system/settings
options.Route = "system/settings";
//授权规则
options.PermissionValidator = (ctx) => true;
options.EditorOptions.EditorOnclick = "return confirm('Are You Sure!?');";
options.EditorOptions.EdtiorConfirmButtonText = "Submit";
options.EditorOptions.EditorEditButtonText = "Edit";
options.EditorOptions.ShouldPagenation = true;

//开启AutoFluentValidation
options.AutoFluentValidationOption.Enable = true;

//支持缓存提供者,默认不使用缓存
options.UseCacheOfNull();
//您也可以使用Biwen.Settings提供内存缓存:MemoryCacheProvider
//options.UseCacheOfMemory();
//使用自定义缓存提供者
//options.UseCache<T>();
//配置当前服务为主节点
options.NotifyOptions.IsNotifyEnable = true;
options.NotifyOptions.Secret = "Biwen.Settings.Notify";
//子节点配置
options.NotifyOptions.EndpointHosts = new[]
{
    "http://localhost:5150"
};
//默认提供EntityFrameworkCore持久化配置项 dbContextType必须配置
//options.UseStoreOfEFCore(options =>
//{
//    options.DbContextType = typeof(MyDbContext);
//});
//使用JsonStore持久化配置项
options.UserStoreOfJsonFile(options =>
{
    options.FormatJson = true;
    options.JsonPath = "systemsetting.json";
});
        
//自行实现的ISettingManager注册
//options.UseSettingManager<T,V>()
});

//提供对`IOptions`和`IConfiguration`直接支持:
builder.Configuration.AddBiwenSettingConfiguration(builder.Services, true);

app.UseBiwenSettings(mapNotifyEndpoint: true, builder: builder =>
{
builder.WithTags("BiwenSettingApi").WithOpenApi();
});

Enjoy!

2024-05-17更新 提供对IOptions,IOptionsSnapshot和IConfiguration直接支持: 帮助参见:releases 2.2.0 +

支持提交更新时验证器自动验证

//模拟的配置项,注意描述信息,以及默认值.初始化将以默认值为准
[Description("微信配置")]
public class WeChatSetting : SettingBase
{
    [Description("AppId")]
    public string AppId { get; set; } = "wx1234567890";

    public string AppSecret { get; set; } = "1234567890";

    public string Token { get; set; } = "1234567890";

    [Description("EncodingAESKey")]
    public string EncodingAESKey { get; set; } = "1234567890";
    //排序
    public override int Order => 500;
    //定义验证器
    public class WeChatSettingValidtor : AbstractValidator<WeChatSetting>
    {
        public WeChatSettingValidtor()
        {
            //验证规则
            RuleFor(x => x.AppId).NotEmpty().Length(12, 32);
            RuleFor(x => x.AppSecret).NotNull().NotEmpty().Length(12, 128);
        }
    }
}

/// <summary>
/// 内置验证器的配置项,推荐使用这种方式 ,同时支持`FluentValidation`和`DataAnnotations`
/// </summary>
[Description("内置验证器的配置项测试")]
public class TestAutoValidSetting : ValidationSettingBase<TestAutoValidSetting>
{
    [StringLength(50, MinimumLength = 3)] // DataAnnotations支持
    public string Name { get; set; } = "Hello"!;

    public TestAutoValidSetting()
    {
        //构造函数中添加验证规则
        RuleFor(x => x.Name).NotEmpty().Length(8, 32);
    }
    override public int Order => 600;
}

//anywhere you can inject
//View:
//@inject WeChatSetting WeChatSetting;

//Service:

//{
//    private readonly WeChatSetting _weChatSetting;
