Abp.RemoteEventBus

What’s this?

受到Abp事件总线的灵感而开发的一个分布式的事件总线，可以跨应用触发事件。基于发布/订阅模式，消息的传递可以通过redis，rabbitmq，kafka等实现。你还能非常容易的实现你自己的方式，通过实现指定接口。支持控制台和web应用。

A distributed event bus, inspired by the Abp event bus, can trigger events across applications. Based on publish / subscribe mode, the message can be passed through redis, rabbitmq, kafka and so on. You can also very easily implement your own way by implementing the specified interface. Support in console and web applications.

How to use?

Publish

    var eventDate = new RemoteEventData("Type_Test")
        {
            Data ={["playload"]=DateTime.Now}
        };
    remoteEventBus.Publish("Topic_Test", eventDate);

    [RemoteEventHandler(ForType = "Type_Test", ForTopic = "Topic_Test")]
    public class RemoteEventHandler : IRemoteEventHandler, ITransientDependency
    {
        public void HandleEvent(RemoteEventArgs eventArgs)
        {
            Logger.Info("receive " + eventArgs.EventData.Data["playload"]);
        }
    }

Configuration

Use kafka

    [DependsOn(typeof(AbpRemoteEventBusKafkaModule))]
    public class DemoModule : AbpModule
    {
        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(typeof(DemoModule).GetAssembly());
        }

        public override void PostInitialize()
        {
            // use kafka
            Configuration.Modules.RemoteEventBus().UseKafka().Configure((setting) =>
            {
                setting.Properties.Add("bootstrap.servers", "192.168.188.142:9092");
                setting.Properties.Add("group.id", "App-Test");
            });
            
            // enable auto subscribe
            // will scan class which use RemoteEventHandlerAttribute and auto subscribe topic base the attribute info
            Configuration.Modules.RemoteEventBus().AutoSubscribe();
        }
    }

Use RabbitMQ

    [DependsOn(typeof(AbpRemoteEventBusRabbitMQModule))]
    public class DemoModule : AbpModule
    {
        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(typeof(DemoModule).GetAssembly());
        }

        public override void PostInitialize()
        {
            // use rabbitmq
            Configuration.Modules.RemoteEventBus().UseRabbitMQ().Configure(setting =>
            {
                //setting.Url = "amqp://guest:guest@127.0.0.1:5672/";
            });
            
            // enable auto subscribe
            // will scan class which use RemoteEventHandlerAttribute and auto subscribe topic base the attribute info
            Configuration.Modules.RemoteEventBus().AutoSubscribe();
        }
    }

Use Redis

    [DependsOn(typeof(AbpRemoteEventBusRedisModule))]
    public class DemoModule : AbpModule
    {
        public override void Initialize()
        {
            IocManager.RegisterAssemblyByConvention(typeof(DemoModule).GetAssembly());
        }

        public override void PostInitialize()
        {   
            // use redis
            Configuration.Modules.RemoteEventBus().UseRedis().Configure((setting) =>
            {
                setting.Server = "127.0.0.1:6379";
            });
            
            // enable auto subscribe
            // will scan class which use RemoteEventHandlerAttribute and auto subscribe topic base the attribute info
            Configuration.Modules.RemoteEventBus().AutoSubscribe();
        }
    }
