快速入门

我们在主页上有不少例子,这是让您入门的第一个:

  1. 定义事件订阅者 ToDoEventSubscriber
// 实现 IEventSubscriber 接口
public class ToDoEventSubscriber : IEventSubscriber
{
    private readonly ILogger<ToDoEventSubscriber> _logger;
    public ToDoEventSubscriber(ILogger<ToDoEventSubscriber> logger)
    {
        _logger = logger;
    }

    [EventSubscribe("ToDo:Create")] // 支持多个
    [EventSubscribe(YourEnum.Message)]   // 支持枚举
    public async Task CreateToDo(EventHandlerExecutingContext context)
    {
        var todo = context.Source;
        _logger.LogInformation("创建一个 ToDo:{Name}", todo.Payload);
        await Task.CompletedTask;
    }

    // 支持枚举类型
    [EventSubscribe(YourEnum.Some)]
    public async Task EnumHandler(EventHandlerExecutingContext context)
    {
        var eventEnum = context.Source.EventId.ParseToEnum(); // 将事件 Id 转换成枚举对象
        await Task.CompletedTask;
    }

    // 支持正则表达式匹配
    [EventSubscribe("(^1[3456789][0-9]{9}$)|((^[0-9]{3,4}\\-[0-9]{3,8}$)|(^[0-9]{3,8}$)|(^\\([0-9]{3,4}\\)[0-9]{3,8}$)|(^0{0,1}13[0-9]{9}$))", FuzzyMatch = true)]
    public async Task RegexHandler(EventHandlerExecutingContext context)
    {
        var eventId = context.Source.EventId;
        await Task.CompletedTask;
    }

    // 支持多种异常重试配置
    [EventSubscribe("test:error", NumRetries = 3)]
    [EventSubscribe("test:error", NumRetries = 3, RetryTimeout = 1000)] // 重试间隔时间
    [EventSubscribe("test:error", NumRetries = 3, ExceptionTypes = new[] { typeof(ArgumentException) })]    // 特定类型异常才重试
    public async Task ExceptionHandler(EventHandlerExecutingContext context)
    {
        var eventId = context.Source.EventId;
        await Task.CompletedTask;
    }
}
  1. 创建控制器 ToDoController,依赖注入 IEventPublisher 服务:
public class ToDoController : ControllerBase
{
    // 依赖注入事件发布者 IEventPublisher
    private readonly IEventPublisher _eventPublisher;
    public ToDoController(IEventPublisher eventPublisher)
    {
        _eventPublisher = eventPublisher;
    }

    // 发布 ToDo:Create 消息
    public async Task CreateDoTo(string name)
    {
        await _eventPublisher.PublishAsync(new ChannelEventSource("ToDo:Create", name));
        // 简化版本
        await _eventPublisher.PublishAsync("ToDo:Create", name);
    }
}
  1. Startup.cs 注册 EventBus 服务:
// 注册 EventBus 服务
services.AddEventBus(builder =>
{
    // 注册 ToDo 事件订阅者
    builder.AddSubscriber<ToDoEventSubscriber>();

    // 通过类型注册
    builder.AddSubscriber(typeof(ToDoEventSubscriber));

    // 批量注册事件订阅者
    builder.AddSubscribers(ass1, ass2, ....);
});
  1. 运行项目:
info: Jaina.Samples.ToDoEventSubscriber[0]
      创建一个 ToDo:Jaina
