要解决abp后台作业管理器和负载均衡的问题,可以按照以下步骤进行:
abp new MyAbpApp
BackgroundJobs
的模块,用于管理后台作业。你可以在MyAbpApp.Application
项目中创建一个新的后台作业类:public class MyBackgroundJob : IBackgroundJob
{
private readonly IMyService _myService;
public MyBackgroundJob(IMyService myService)
{
_myService = myService;
}
public async Task ExecuteAsync()
{
// 在这里编写后台作业的逻辑
await _myService.DoWorkAsync();
}
}
MyAbpApp.Application
项目的MyAbpAppApplicationModule
类中,重写PreConfigureServices
方法,并在其中注册后台作业服务:public override void PreConfigureServices(ServiceConfigurationContext context)
{
context.Services.OnRegistereing(ConfigureBackgroundJobs);
}
private void ConfigureBackgroundJobs(ServiceConfigurationContext context, IOnRegistereingContext onRegistereingContext)
{
onRegistereingContext.Services.AddTransient();
}
IBackgroundJobManager
接口,并调用EnqueueAsync
方法来添加后台作业。public class MyApplicationService : ApplicationService
{
private readonly IBackgroundJobManager _backgroundJobManager;
public MyApplicationService(IBackgroundJobManager backgroundJobManager)
{
_backgroundJobManager = backgroundJobManager;
}
public async Task CreateJobAsync()
{
await _backgroundJobManager.EnqueueAsync(new MyBackgroundJob());
}
}
在MyAbpApp.HttpApi.Host
项目中,你可以使用ABP CLI命令行工具来添加Consul和Ocelot的集成。首先,安装Consul和Ocelot的集成包:
abp add-package Volo.Abp.AspNetCore.MultiTenancy.Vue
abp add-package Volo.Abp.AspNetCore.MultiTenancy.Vue
然后,在MyAbpAppHttpApiHostModule
类中,添加Consul和Ocelot的配置:
public override void ConfigureServices(ServiceConfigurationContext context)
{
Configure(options =>
{
options.Address = new Uri("http://localhost:8500");
});
Configure(options =>
{
options.GatewayRoutes.Add(new OcelotRouteConfiguration
{
RouteKey = "MyService",
UpstreamPathTemplate = "/api/{everything}",
UpstreamHttpMethod = new List { "Get", "Post" },
DownstreamScheme = "http",
DownstreamHostAndPorts = new List
{
new DownstreamHostAndPort
{
Host = "localhost",
Port = 5001
},
new DownstreamHostAndPort
{
Host = "localhost",
Port = 5002
}
}
});
});
// ...
}
IHttpClientFactory
和LoadBalancerHttpClientFactory
来创建一个负载均衡的HttpClient。public class MyApplicationService : ApplicationService
{
private readonly IHttpClientFactory _httpClientFactory;
public
