在C#中模拟Spring的Spring Cloud Bus的事件总线功能,可以使用以下步骤:
public class MyEvent
{
public string Message { get; set; }
public MyEvent(string message)
{
Message = message;
}
}
public class EventPublisher
{
private readonly IHubContext<MyEvent> _hubContext;
public EventPublisher(IHubContext<MyEvent> hubContext)
{
_hubContext = hubContext;
}
public async Task PublishEventAsync(MyEvent eventData)
{
await _hubContext.Clients.All.SendAsync("ReceiveEvent", eventData);
}
}
public class EventSubscriber
{
private readonly IHubConnection _hubConnection;
public EventSubscriber(IHubConnection hubConnection)
{
_hubConnection = hubConnection;
}
public async Task SubscribeToEventsAsync()
{
await _hubConnection.StartAsync();
_hubConnection.On<MyEvent>("ReceiveEvent", (eventData) =>
{
Console.WriteLine($"Received event: {eventData.Message}");
});
}
}
public class EventBus
{
private readonly HubConnectionBuilder _hubConnectionBuilder;
public EventBus(HubConnectionBuilder hubConnectionBuilder)
{
_hubConnectionBuilder = hubConnectionBuilder;
}
public async Task StartAsync()
{
var hubConnection = _hubConnectionBuilder.WithUrl("http://localhost:5000/eventbus").Build();
var eventPublisher = new EventPublisher(new HubContext<MyEvent>(hubConnection));
var eventSubscriber = new EventSubscriber(hubConnection);
await eventSubscriber.SubscribeToEventsAsync();
await hubConnection.StartAsync();
}
public async Task StopAsync()
{
await _hubConnectionBuilder.WithUrl("http://localhost:5000/eventbus").Build().StopAsync();
}
}
public class Program
{
public static async Task Main(string[] args)
{
var eventBus = new EventBus(new HubConnectionBuilder());
await eventBus.StartAsync();
var eventPublisher = new EventPublisher(new HubContext<MyEvent>(eventBus._hubConnectionBuilder.Build()));
await eventPublisher.PublishEventAsync(new MyEvent("Hello, Spring Cloud Bus!"));
await Task.Delay(1000);
await eventBus.StopAsync();
}
}
这个示例展示了如何在C#中模拟Spring的Spring Cloud Bus的事件总线功能。你可以根据自己的需求对这个示例进行修改和扩展。
