Quartz.Net_持久化

简述

通常而言，Quartz.Net的数据默认是存储在运存中的，换言之：断电即失。所以在默认情况下，当系统重启后，原先的所有任务、触发器、调度器都会失效

为避免上述情况的发生，可以对Quartz.Net进行持久化设置，令数据储存在DB中

解决方式

1.安装依赖（以MySQL为例）

问：为什么需要同时安装MySql.Data与Pomelo.EntityFrameworkCore.MySql？

答：因为我本人平时是使用Pomelo.EntityFrameworkCore.MySql连接DB的，但Quartz.Net硬编码使用MySql.Data连接DB

2.创建DB， SQL文件可参考https://github.com/quartznet/quartznet/tree/main/database/tables

此处给出MySQL的命令

DB结构

3.通过有参构造函数实例化调度器，硬编码中的信息依据实际情况修改

cs 复制代码

NameValueCollection pars = new()
{
    //scheduler名字
    ["quartz.scheduler.instanceName"] = "MyAdoJobStoreScheduler",
    //类型为JobStoreXT,事务
    ["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz",
    //数据源名称
    ["quartz.jobStore.dataSource"] = "QuartzDb",
    //使用mysql的Ado操作代理类
    ["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.MySQLDelegate, Quartz",
    //数据源连接字符串
    ["quartz.dataSource.QuartzDb.connectionString"] = @"server=localhost;Database=quartzmanager;user id=root;password=123456;SslMode=none;",
    //数据源的数据库
    ["quartz.dataSource.QuartzDb.provider"] = "MySql",
    //序列化类型
    ["quartz.serializer.type"] = "json",
    //自动生成scheduler实例ID，主要为了保证集群中的实例具有唯一标识
    ["quartz.scheduler.instanceId"] = "AUTO"
};
//实例化调度器
ISchedulerFactory schedulefactory = new StdSchedulerFactory(pars);
IScheduler scheduler = schedulefactory.GetScheduler().Result;

//开启调度器
await scheduler.Start();

4.创建作业时设置 StoreDurably()

cs 复制代码

IJobDetail job = JobBuilder.Create<MyJob>()
    .StoreDurably()
    .WithIdentity("job")
    .Build();

5.测试示例

IJob实现类

cs 复制代码

    public class MyJob : IJob
    {
        public Task Execute(IJobExecutionContext context)
        {
            Console.WriteLine("===============");

            return Task.CompletedTask;
        }
    }

Program.cs

cs 复制代码

internal class Program
{
    static async Task Main(string[] args)
    {
        NameValueCollection pars = new()
        {
            //scheduler名字
            ["quartz.scheduler.instanceName"] = "MyAdoJobStoreScheduler",
            //类型为JobStoreXT,事务
            ["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz",
            //数据源名称
            ["quartz.jobStore.dataSource"] = "QuartzDb",
            //使用mysql的Ado操作代理类
            ["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.MySQLDelegate, Quartz",
            //数据源连接字符串
            ["quartz.dataSource.QuartzDb.connectionString"] = @"server=localhost;Database=quartzmanager;user id=root;password=123456;SslMode=none;",
            //数据源的数据库
            ["quartz.dataSource.QuartzDb.provider"] = "MySql",
            //序列化类型
            ["quartz.serializer.type"] = "json",
            //自动生成scheduler实例ID，主要为了保证集群中的实例具有唯一标识
            ["quartz.scheduler.instanceId"] = "AUTO"
        };
        //实例化调度器
        ISchedulerFactory schedulefactory = new StdSchedulerFactory(pars);
        IScheduler scheduler = schedulefactory.GetScheduler().Result;

        //开启调度器
        await scheduler.Start();

        //创建一个作业
        IJobDetail job = JobBuilder.Create<MyJob>()
            .StoreDurably()
            .WithIdentity("job1")//名称，分组
            .Build();

        //创建一个触发器
        ITrigger trigger = TriggerBuilder.Create()
            .WithIdentity("trigger1")//名称，分组
            .StartAt(new DateTimeOffset(DateTime.Now))//从启动的时候开始执行
            .WithSimpleSchedule(b =>
            {
                b.WithIntervalInSeconds(2)//2秒执行一次
                 .WithRepeatCount(10)
                 .WithMisfireHandlingInstructionFireNow();
            })
            .Build();

        //把作业，触发器加入调度器
        await scheduler.ScheduleJob(job, trigger);

        Thread.Sleep(10000);
    }
}
