.NETCore 知识点记录-QuartzCore 定时任务

1.定时任务框架：

1.Pomelo.AspNetCore.TimedJob

2.Quartzcore

第二种已经实现 基于 官网 最新 3.0Bate版本

//核心代码:  参照官网 ：

官网地址：  https://www.quartz-scheduler.net/documentation/quartz-3.x/quick-start.html

需要注意的地方：

publicclassHelloJob:IJob{publicTaskExecute(IJobExecutionContextcontext){awaitConsole.Out.WriteLineAsync("Greetings from HelloJob!");}}

官网在介绍 HelloJob的时候

在EF里面  await  是要 配合 async 来使用的  (写成下面这样就好)

publicclassHelloJob:IJob{public asyncTaskExecute(IJobExecutionContextcontext){awaitConsole.Out.WriteLineAsync("Greetings from HelloJob!");}}

namespace CCDN.XXXX
{
    class Program
    {
        static void Main(string[] args)
        {         
            //LogProvider.SetCurrentLogProvider(new ConsoleLogProvider());
            RunProgram().GetAwaiter().GetResult();
        }
        
        private static async Task RunProgram()
        {
            int i = 0;
            DateTime myStartTime = Convert.ToDateTime("2016-12-08");
            try

                ISimpleTrigger trigger = (ISimpleTrigger)TriggerBuilder.Create()
                    .WithIdentity("trigger1") // 给任务一个名字
                    .StartAt(myStartTime) // 设置任务开始时间
                    .ForJob("job1", "group1") //给任务指定一个分组
                    .WithSimpleSchedule(x => x
                    .WithIntervalInSeconds(20)  //循环的时间
                    .RepeatForever())               
                    .Build();


                // 等待执行任务
                await scheduler.ScheduleJob(job, trigger);


                // some sleep to show what's happening
                //await Task.Delay(TimeSpan.FromMilliseconds(2000));


                // and last shut down the scheduler when you are ready to close your program
                //await scheduler.Shutdown();
                i++;
                Console.ReadLine();
                Console.WriteLine(DateTime.Now.ToString()+"这是第"+i+"次执行任务");
            }
            catch (SchedulerException se)
            {
                await Console.Error.WriteLineAsync(se.ToString());
            }
        }
}
