【netcore基础】.Net core自动作业之Hangfire

nuget搜索：Hangfire

安装即可，这里我选择的是 1.7.0-beta1 版本

我是用这个集成到了 mvc api里

这里需要在 Startup 文件里进行如下配置

在配置方法 ConfigureServices 里配置数据库，这是用的是sqlserver数据库初始化

            var hangfireConnStr = _configuration["AppSettings:HangfireConnectionString"];
            services.AddHangfire(configuration => configuration.UseSqlServerStorage(hangfireConnStr));

如果数据库是mysql，使用下面语句初始化，需要引用 Hangfire.MySql

【netcore基础】.Net core自动作业之Hangfire_netcore微服务搭建

            var hangfireMysqlConnStr = _configuration["AppSettings:HangfireMysqlConnectionString"];
            services.AddHangfire(configuration => configuration.UseStorage(
                new MySqlStorage(
                    hangfireMysqlConnStr,
                    new MySqlStorageOptions
                    {
                        TransactionIsolationLevel = IsolationLevel.ReadCommitted,
                        QueuePollInterval = TimeSpan.FromSeconds(15),
                        JobExpirationCheckInterval = TimeSpan.FromHours(1),
                        CountersAggregateInterval = TimeSpan.FromMinutes(5),
                        PrepareSchemaIfNecessary = true,
                        DashboardJobListLimit = 50000,
                        TransactionTimeout = TimeSpan.FromMinutes(1),
                        TablesPrefix = ""
                    })));

在配置方法 Configure 里需要配置下管理员后台

            app.UseHangfireServer();
            app.UseHangfireDashboard();

这样我们就可以通过后台操作管理作业了

地址如下

https://localhost:5001/hangfire

这里可以看到正在跑的作业和执行情况

【netcore基础】.Net core自动作业之Hangfire_netcore微服务搭建_04

不过这个后台只能在服务器本机上访问，为了保证安全，无法通过域名访问操作

添加调用代码很简单，在每次系统启动的时候，配置如下，如果没有添加；有了就更新

RecurringJob.AddOrUpdate(() => UpdateMerchIndex(), Cron.MinuteInterval(3));

这里是指每隔三分钟调用一次 UpdateMerchIndex() 方法。

是不是很简单呢

数据库需要初始化几个表

这里附送数据库初始化建表SQL语句

sqlserver
