### CAP background task is starting. 日志运行到这一句整个项目就卡住了

[cethink]

代码如下：

public override void ConfigureServices(ServiceConfigurationContext context)
{
    var hostingEnvironment = context.Services.GetHostingEnvironment();
    var configuration = context.Services.GetConfiguration();

    ConfigureUrls(configuration);
    ConfigureAutoMapper(context);
    ConfigureSwagger(context.Services, configuration);
    ConfigureAutoApiControllers();
    ConfigureVirtualFiles(hostingEnvironment);
    ConfigureLocalization();
    ConfigureCors(context, configuration);
    ConfigureDataProtection(context);
    ConfigureEfCore(context);

    AbpOpenIddictDbProperties.DbTablePrefix = "";
    AbpIdentityDbProperties.DbTablePrefix = "";
    AbpPermissionManagementDbProperties.DbTablePrefix = "";

    context.Services.AddAlwaysAllowAuthorization();

    context.Services.AddJsonNamingPolicyNull();

    context.Services.AddDisAntiForgery();

    context.Services.AddRegistryCenter(configuration);

    /*
     * 配置EventBus，其它代码都试过了，加了这句后就卡了，也试过把代码调换顺序，可以运行成功一次，然后又不行了
     */
    context.Services.AddEventBus<ES_UserServiceDbContext>(configuration);
}

public static IServiceCollection AddEventBus<T>(this IServiceCollection services, IConfiguration configuration) where T : DbContext
{
    services.AddCap(options =>
    {
        options.UseRabbitMQ(rb =>
        {
            rb.HostName = configuration.GetValue<string>("EventBus:HostName")!;
            rb.UserName = configuration.GetValue<string>("EventBus:UserName")!;
            rb.Password = configuration.GetValue<string>("EventBus:Password")!;
            rb.Port = configuration.GetValue<int>("EventBus:Port")!;
            rb.VirtualHost = configuration.GetValue<string>("EventBus:VirtualHost")!;
        });

        options.UseEntityFramework<T>();
        options.UseMySql(configuration.GetValue<string>("EventBus:ConnectionString")!);

        options.UseDashboard();

        options.FailedRetryCount = configuration.GetValue<int>("EventBus:FailedRetryCount")!;
        options.FailedRetryInterval = configuration.GetValue<int>("EventBus:FailedRetryInterval")!;
    });

    return services;
