.netcore控制台->定时任务Quartz
之前做数据同步时,用过timer、window服务,现在不用那么费事了,可以使用Quartz,并且配置灵活,使用cron表达式配置XML就可以。我用的是3.0.7版本支持.netcore。
- 首先创建一个.netcore控制台应用程序,添加Quartz、Quartz.Jobs、Quartz.Plugins引用,这里面添加了PostgreSql数据库的连接方法,其它数据库可以做为参考,添加Npgsql、Npgsql.EntityFrameworkCore.PostgreSQL引用,目录结构如下
- 创建数据库DBContext类
-
using System; using System.Collections.Generic; using System.Text; using Microsoft.EntityFrameworkCore; namespace QuartzPro.DbContext { public class PostgreDbContext : Microsoft.EntityFrameworkCore.DbContext { private string _conn; public PostgreDbContext(DbContextOptions<PostgreDbContext> options) : base(options) { } public PostgreDbContext(string conn) { _conn = conn; } protected override void OnModelCreating(ModelBuilder builder) { base.OnModelCreating(builder); //builder.Entity<syrequest_main>().ToTable("book", "pro"); } // public virtual DbSet<book> book { get; set; } } }
- 创建Job类
-
using System; using System.Collections.Generic; using System.IO; using System.Text; using System.Threading.Tasks; using Microsoft.Extensions.Logging; using Quartz; namespace QuartzPro.Jobs {
[DisallowConcurrentExecution] public class SyncUserInfoService : IJob { private readonly ILogger<SyncUserInfoService> _logger; public SyncUserInfoService() { _logger = BootStrapIoc.GetService<ILoggerFactory>().CreateLogger<SyncUserInfoService>(); } public Task Execute(IJobExecutionContext context) { _logger.LogDebug($"SyncUserInfoService Execute start..."); return Task.Run(() => { using (StreamWriter sw = new StreamWriter(@"D:\print.txt", true, Encoding.UTF8)) { sw.WriteLine(DateTime.Now + "任务执行中..."); sw.Close(); } }); } } }
-
- 创建依赖注入类
-
using Microsoft.Extensions.Configuration; using Microsoft.Extensions.DependencyInjection; using Microsoft.Extensions.Logging; using QuartzPro.DbContext; namespace QuartzPro { public static class BootStrapIoc { /// <summary> /// IOC容器 /// </summary> private static IServiceCollection serviceCollection { get; } = new ServiceCollection(); /// <summary> /// 初始化IOC容器 /// </summary> public static void InitIoc() { var configuration = new ConfigurationBuilder().AddJsonFile("appsettings.json", optional: true, reloadOnChange: true).AddEnvironmentVariables().Build(); var identityConn = configuration.GetConnectionString("IdentityConnection"); //db serviceCollection.AddTransient(_ => new PostgreDbContext(identityConn)); //log serviceCollection.AddLogging(configure => { configure.AddConfiguration(configuration.GetSection("Logging")); configure.AddConsole(); }); //config serviceCollection.AddSingleton<IConfiguration>(configuration); } /// <summary> /// 获取实体 /// </summary> /// <typeparam name="T"></typeparam> /// <returns></returns> public static T GetService<T>() { return serviceCollection.BuildServiceProvider().GetService<T>(); } } }
- 创建任务监听XML文件
-
<?xml version="1.0" encoding="utf-8" ?> <job-scheduling-data xmlns="http://quartznet.sourceforge.net/JobSchedulingData" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0"> <processing-directives> <overwrite-existing-data>true</overwrite-existing-data> </processing-directives> <schedule> <!--同步用户信息:10分钟一次--> <job> <name>SyncUserInfoService</name> <group>GroupUserInfoManager</group> <description>同步用户信息</description> <job-type>QuartzPro.Jobs.SyncUserInfoService, QuartzPro</job-type> <durable>true</durable> <recover>false</recover> </job> <trigger> <cron> <name>TriggerSyncUserInfoService</name> <group>GroupTriggerUserInfoManager</group> <job-name>SyncUserInfoService</job-name> <job-group>GroupUserInfoManager</job-group> <start-time>2019-07-30T15:15:00.0Z</start-time> <cron-expression>0 0/10 * * * ?</cron-expression> <!--<cron-expression>1 0 0 * * ?</cron-expression>--> </cron> </trigger> </schedule> </job-scheduling-data>
- json配置文件
-
{ "Logging": { "LogLevel": { "Default": "Debug", "System": "Information", "Microsoft": "Information" }, "Console": { "IncludeScopes": true } }, "ConnectionStrings": { "IdentityConnection": "User ID=admin;Password=123456;Host=.;Port=5432;Database=identities;" } }
- Program类,注意该项目为控制台程序 UserInfoManager.xml和 appsettings.json,需要右键设置为可输出文件
-
using System; using System.Collections.Specialized; using System.Threading.Tasks; using Quartz; using Quartz.Impl; namespace QuartzPro { class Program { private static void Main(string[] args) { BootStrapIoc.InitIoc(); var task = Run(); task.Wait(); task.ConfigureAwait(false); while (true) { Console.Read(); } } public static async Task Run() { try { var properties = new NameValueCollection { ["quartz.plugin.triggHistory.type"] = "Quartz.Plugin.History.LoggingJobHistoryPlugin, Quartz.Plugins", ["quartz.plugin.jobInitializer.type"] = "Quartz.Plugin.Xml.XMLSchedulingDataProcessorPlugin, Quartz.Plugins", ["quartz.plugin.jobInitializer.fileNames"] = "UserInfoManager.xml", ["quartz.plugin.jobInitializer.failOnFileNotFound"] = "true", ["quartz.plugin.jobInitializer.scanInterval"] = "120" }; ISchedulerFactory sf = new StdSchedulerFactory(properties); IScheduler scheduler = await sf.GetScheduler(); Console.WriteLine("start the schedule"); await scheduler.Start(); Console.WriteLine("end"); } catch (SchedulerException se) { await Console.Error.WriteLineAsync(se.ToString()); } catch (Exception ex) { Console.Write($"err={ex.ToString()}"); } } } }
