Biwen.Settings 2.0.1

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!

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.HasPermission = (ctx) => true;
        options.EditorOption.EditorOnclick = "return confirm('Are You Sure!?');";
        options.EditorOption.EdtiorConfirmButtonText = "Submit";
        options.EditorOption.EditorEditButtonText = "Edit";
        options.EditorOption.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.NotifyOption.IsNotifyEnable = true;
        options.NotifyOption.Secret = "Biwen.Settings.Notify";
        //子节点配置
        options.NotifyOption.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>()
    });

   //...............
   app.MapBiwenSettingApi();//api
   app.UseBiwenSettings();//mvc

Enjoy!
