• ABP4.6旧版 集成 MassTransit rabbitMQ 重试,熔断


    废话不多说!!!上代码:

    代码粗略!本人本地演示====

    1提前安装 RabbitMQ 服务等

    2:配置方法图:

     代码:

    /// <summary>
    /// 配置 Masstransit
    /// </summary>
    /// <param name="services"></param>
    private void ConfigureDistributedEventBus(IServiceCollection services)
    {
    // var options = _appConfiguration.GetSection("RabbitMQConfigInfo");//.Get<MassTransitEventBusOptions>();

    services.AddHealthChecks();

    services.Configure<HealthCheckPublisherOptions>(options =>
    {
    options.Delay = TimeSpan.FromSeconds(2);
    options.Predicate = (check) => check.Tags.Contains("ready");
    });
    var mqConnectionString = "rabbitmq://127.0.0.1"; // + options.ConnectionString;
    services.AddMassTransit(mtConfig =>
    {
    //inject consumers into IOC from assembly
    // mtConfig.AddConsumersFromContainer(Assembly.GetExecutingAssembly());

    mtConfig.AddConsumers(Assembly.GetExecutingAssembly());
    //mtConfig.AddConsumers(typeof(AuthCenterEventBusHostModule));
    //mtConfig.AddConsumers(typeof(SmsTokenValidationCreatedEvent));
    mtConfig.SetKebabCaseEndpointNameFormatter();
    mtConfig.AddBus(provider =>
    {
    var bus = Bus.Factory.CreateUsingRabbitMq(mqConfig =>
    {
    mqConfig.Host(new Uri(mqConnectionString), h =>
    {
    //h.Username(options.UserName);
    //h.Password(options.Password);
    h.Username("guest");
    h.Password("guest");
    });
    // set special message serializer
    mqConfig.UseBsonSerializer();

    // integrated existed logger compontent
    // mqConfig.UseExtensionsLogging(provider.GetService<ILoggerFactory>());

    mqConfig.ReceiveEndpoint("BangFaoffsite.Web", q =>
    {
    q.UseRetry(ret =>
    {
    ret.Interval(3, TimeSpan.FromSeconds(10)); // 每隔10s重试一次,最多重试3次
    });

    //set rabbitmq prefetch count
    q.PrefetchCount = 20000000;

    //set message retry policy
    q.UseMessageRetry(r => r.Interval(3, 100));
    q.UseCircuitBreaker(cb =>
    {
    cb.TrackingPeriod = TimeSpan.FromMinutes(1); // 跟踪周期:1min
    cb.TripThreshold = 15; // 失败比例达到15%后才会打开熔断器
    cb.ActiveThreshold = 5; // 至少发生5次请求后才会打开熔断器
    cb.ResetInterval = TimeSpan.FromMinutes(3); // 熔断时间间隔:5mins
    });
    // q.Consumer<SmsTokenValidationCreatedEvent>(provider);
    //EndpointConvention.Map<SmsTokenValidationCreatedEvent>(q.InputAddress);

    });

    //mqConfig.ReceiveEndpoint(host, "user-synchronization", q =>
    //{
    // //set rabbitmq prefetch count
    // q.PrefetchCount = 50;
    // //q.UseRateLimit(100, TimeSpan.FromSeconds(1));
    // //q.UseConcurrencyLimit(2);

    // //set message retry policy
    // q.UseMessageRetry(r => r.Interval(3, 100));

    // q.Consumer<UserSyncEventConsumer>(provider);
    // EndpointConvention.Map<UserSyncEvent>(q.InputAddress);
    //});

    mqConfig.ConfigureEndpoints(provider);

    //mqConfig.UseAuditingFilter(provider, o =>
    //{
    // o.ReplaceAuditing = true;
    //});

    });
    // set authtication middleware for user identity
    // bus.ConnectAuthenticationObservers(provider);
    bus.Start();
    return bus;
    });
    });
    }

    调用:

     代码:

     ConfigureDistributedEventBus(services);

    3:appsettings.json配置:

     定义消费者类:

     =内部:

     代码:

    public class AuthCenterEventBusHostModule : IConsumer<IOrder>
    {
    public Task Consume(ConsumeContext<IOrder> context)
    {
    Console.WriteLine($" {DateTime.Now}失败的成功===AuthCenterEventBusHostModule{ context.Message.Name}");
    context.NotifyConsumed(TimeSpan.FromSeconds(1), typeof(IUser).Name);
    return context.ConsumeCompleted;
    }


    }

    三:协议对象:

    代码:

    /// <summary>
    /// 传输协议
    /// </summary>
    public interface IData
    {
    string Name { get; set; }
    string Url { get; set; }
    }
    /// <summary>
    /// 订单协议
    /// </summary>
    public interface IOrder
    {
    string Name { get; set; }
    }

    /// <summary>
    /// 用户协议
    /// </summary>
    public interface IUser
    {
    string Name { get; set; }
    }

     四:其他两个消费者类似;

    五:生产者定义:在控制器中使用

     

     代码就不贴了;比较简单,亲自写写加深印象!!哈哈哈

    接下来启动项目====测试!!!
