在 MassTransit 上禁用循环消息消费
Disable round-robin message consumption on MassTransit
我已经创建了一个基本演示 pub/sub 应用程序,它可以在本地主机上使用 MassTransit。
我想要实现的是发布一条消息,所有订阅者都应该收到消息。
目前,在我的环境中,我启动了一个发布者应用程序和两个订阅者应用程序。但是当我发布消息时,订阅者轮流接收消息。
我的pub/sub代码:
发布:
var bus = Bus.Factory.CreateUsingRabbitMq(config =>
{
config.Host(new Uri("rabbitmq://localhost/"), h => { });
config.ExchangeType = ExchangeType.Fanout;
});
var busHandle = bus.Start();
bus.Publish<SomethingHappened>(message);
订阅者使用此代码:
var bus = Bus.Factory.CreateUsingRabbitMq(config =>
{
var host = config.Host(new Uri("rabbitmq://localhost/"), h => { });
config.ReceiveEndpoint(host, "MassTransitExample_Queue", e => e.Consumer<SomethingHappenedConsumer>());
});
var busHandle = bus.Start();
Console.ReadKey();
busHandle.Stop();
在阅读下面的文章时,我发现队列名称必须是唯一的

When building your bus and registering an endpoint like so:
sbc.ReceiveEndpoint(...), one has to be sure that the queueName
parameter is unique.
所以我的订阅者代码现在看起来像这样:
var bus = Bus.Factory.CreateUsingRabbitMq(config =>
{
var host = config.Host(new Uri("rabbitmq://localhost/"), h => { });
config.ReceiveEndpoint(host, "MTExQueue_" + Guid.NewGuid().ToString(), e => e.Consumer<SomethingHappenedConsumer>());
});
var busHandle = bus.Start();
Console.ReadKey();
busHandle.Stop();
