.net core 基于Hangfire+Mysql持久化实现定时任务配置方法
1.negut引入hangfire相关包Hangfire.AspNetCore，Hangfire.Core，Hangfire.Dashboard.BasicAuthorization，Hangfire.MySqlStorage
2.Appsetting 配置hangfire资源
"HangFire": {
"Connection": "Server=127.0.0.1;uid=root;pwd=wakamysql666;database=Hangfire_DB;AllowLoadLocalInfile=true;Allow User Variables=True;",
"pathMatch": "/hangfire",
"Login": "login",
"PasswordClear": "pwd"
},3.自定义扩展类
/// <summary>
/// 任务调度
/// </summary>
public static class HangfireSetup
{
public static void AddHangfireSetup(this IServiceCollection services)
{
if (services == null) throw new ArgumentNullException(nameof(services));
if (services == null) throw new ArgumentNullException(nameof(services));
services.AddHangfire(configuration => configuration
.SetDataCompatibilityLevel(CompatibilityLevel.Version_170)//此方法 只初次创建数据库使用即可
.UseSimpleAssemblyNameTypeSerializer()
.UseRecommendedSerializerSettings()
.UseStorage(new MySqlStorage(Appsettings.app("HangFire", "Connection"), new MySqlStorageOptions
{
TransactionIsolationLevel =
(IsolationLevel?) System.Data.IsolationLevel.ReadCommitted, //事务隔离级别。默认是读取已提交
QueuePollInterval = TimeSpan.FromSeconds(15), //- 作业队列轮询间隔。默认值为15秒。
JobExpirationCheckInterval = TimeSpan.FromHours(1),
CountersAggregateInterval = TimeSpan.FromMinutes(5),
PrepareSchemaIfNecessary = false, // 如果设置为true，则创建数据库表。默认是true
DashboardJobListLimit = 50000,
TransactionTimeout = TimeSpan.FromMinutes(1),
TablesPrefix = "Hangfire"
})));
services.AddHangfireServer();
}
}4.在startupConfigureServices注入扩展
services.AddHangfireSetup();//任务调度
5.配置MIddleware
//任务调度中间件
public static class HangfireMiddleware
{
public static void UseHangfireMiddleware(this IApplicationBuilder app)
{
if (app == null) throw new ArgumentNullException(nameof(app));
app.UseHangfireServer(); //配置服务//ConfigureOptions()
app.UseHangfireDashboard(Appsettings.app("HangFire", "pathMatch"), HfAuthor()); //配置面板
//BackgroundJob.Enqueue(() => Console.WriteLine("Hello world from Hangfire!"));
HangfireService(); //配置各个任务
}
/// <summary>
/// 配置账号模板信息
/// </summary>
/// <returns></returns>
public static DashboardOptions HfAuthor()
{
var filter = new BasicAuthAuthorizationFilter(
new BasicAuthAuthorizationFilterOptions
{
SslRedirect = false,
RequireSsl = false,
LoginCaseSensitive = false,
Users = new[]
{
new BasicAuthAuthorizationUser
{
Login = Appsettings.app("HangFire", "Login"), //可视化的登陆账号
PasswordClear = Appsettings.app("HangFire", "PasswordClear") //可视化的密码
}
}
});
return new DashboardOptions
{
Authorization = new[] {filter}
};
}
/// <summary>
/// 配置启动
/// </summary>
/// <returns></returns>
public static BackgroundJobServerOptions ConfigureOptions()
{
return new()
{
Queues = new[] {"Job", nameof(HangfireConfigureQueue.picturetooss)}, //队列名称，只能为小写
WorkerCount = Environment.ProcessorCount * 5, //并发任务
ServerName = "HangfireServer" //代表服务名称
};
}
#region 配置服务
public static void HangfireService()
{
// "0 0 1 * * ? " 每天凌晨一点执行阿里云OSS
RecurringJob.AddOrUpdate<IOrderItemInfoService>(_ => _.JobOSS(), "0 0 1 * * ? ", TimeZoneInfo.Local,
nameof(HangfireConfigureQueue.picturetooss));
// "0 0 1 * * ? " 每天早上七点执行定时任务更新汇率
RecurringJob.AddOrUpdate<ICurrencyInfosService>(_ => _.UpdateRateByJob(), "0 0 7 * * ? ",
TimeZoneInfo.Local, nameof(HangfireConfigureQueue.picturetooss));
}
#endregion
}6.startupConfigure配置使用中间件
app.UseHangfireMiddleware();//Job效果图：
结语：到此hangfire实现定时任务的配置已经全部完成。
