NetCore 使用Quartz定时执行任务
1.Nuget
install-package Quartz.Extensions.Hosting
2.添加文件：WhileJob
/// <summary> /// while quartz job /// </summary> [DisallowConcurrentExecution] public class WhileJob : IJob { #region 依赖注入 /// <summary> /// 日志注入 /// </summary> private readonly ILogger _logger; #endregion #region 构造函数注入 /// <summary> /// 构造函数注入 /// </summary> /// <param name="logger"></param> /// <param name="configuration"></param> public WhileJob(ILogger<WhileJob> logger) { _logger = logger; } #endregion /// <summary> /// /// </summary> /// <param name="context"></param> /// <returns></returns> public Task Execute(IJobExecutionContext context) { _logger.LogInformation("Hello World!"); return Task.CompletedTask; } }
3.添加文件：QuartzExtend
/// <summary> /// QuartZ.net 扩展类 /// </summary> public static class QuartzExtend { /// <summary> /// 自定义扩展方法： 把Quartz添加到服务容器 /// </summary> /// <param name="services"></param> /// <param name="configuration"></param> public static void AddCustQuartz(this IServiceCollection services, IConfiguration configuration) { // Add the required Quartz.NET services services.AddQuartz(q => { // Use a Scoped container to create jobs. I'll touch on this later q.UseMicrosoftDependencyInjectionScopedJobFactory(); // 控制是否运行quartz if (configuration["CustData:WhileRouterCron"].Equals("true")) { q.AddCustJob<WhileJob>("0 * * * * ? *"); } }); // Add the Quartz.NET hosted service services.AddQuartzHostedService(q => q.WaitForJobsToComplete = true); // other config } /// <summary> /// 封装Quartz添加job代码 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="q"></param> /// <param name="cron"></param> private static void AddCustJob<T>(this IServiceCollectionQuartzConfigurator q, string cron) where T : IJob { // Create a "key" for the job var keyName = typeof(T).Name; var jobKey = new JobKey(keyName); // Register the job with the DI container q.AddJob<T>(opts => opts.WithIdentity(jobKey)); // Create a trigger for the job q.AddTrigger(opts => opts.ForJob(jobKey) // link to the job .WithIdentity($"{keyName}-trigger") // give the trigger a unique name .WithCronSchedule(cron)); // 定时启动 } }
4.Startup.ConfigureServices
services.AddCustQuartz(_configuration);
5.防止IIS自动回收线程
5.1.IIS 防止自动回收5.2.添加一个间隔20分钟的job，模拟请求当前应用的接口
