我使用RabbitMQ与C#,MassTransit,Autofac.

我有一个预定的(5秒)工作来消耗队列.

这项工作大约2个小时,然后突然停止.当我搜索日志时,我发现了这个：

Scope —> An exception occurred during bus creation (See inner
exception for det ails.) —> MassTransit.ConfigurationException: An
exception occurred during bus creation —>
System.OutOfMemoryException: Exception of type ‘System.OutOfMemoryException’ was thrown.

这些是我在MassTransit中配置Autofac的代码块：

builder.Register(context =>
{
    var busControl = Bus.Factory.CreateUsingRabbitMq(cfg =>
    {
        cfg.Host(new Uri(Globals.QueueUrl), h =>
        {
            h.Username(Globals.QueueUserName);
            h.Password(Globals.QueuePassword);
        });

        cfg.ReceiveEndpoint("create_sales_queue",
            ec =>
            {
                ec.Consumer<CreateSalesConsumer>(context);
                ec.UseRetry(p => p.Incremental(10, TimeSpan.FromMilliseconds(200), TimeSpan.FromMilliseconds(200)));
            });

    });
    return busControl;
})
    .InstancePerDependency()
    .As<IBusControl>()
    .Named<IBusControl>(GenericIntegrationTask.CreateSalesTask.ToString());

这些是预定的工作代码：

try
{

    var bus = container.ResolveNamed<IBusControl>(GenericIntegrationTask.CreateSalesTask.ToString());
    bus.Start();
    Thread.Sleep(2000);
    bus.Stop();        
}
catch (Exception e)
{
    Console.WriteLine(e);
}  

提前致谢.

解决方法:

您永远不应该为每个依赖项或每个请求注册您的IBus.它必须是单个实例.

您还需要在应用启动时启动总线,并在应用停止时停止总线.
