上一章介绍了log4net的简单配置，这一章介绍一下quartz的简单使用，下一章介绍一下我得权限使用，然后就结束

本章主要介绍：

quartz在asp.net core中的使用

这个项目虽小，但是及其容易扩展，后面的业务直接能丢进来，使其更加丰富

废话不说开始介绍

一.基础类配置

　　在domain里定义IJobCenter接口

　　技术分享图片

　　代码如下：

public interface IJobCenter
    {
        /// <summary>
        /// 添加定时任务
        /// </summary>
        /// <param name="m"></param>
        /// <returns></returns>
        Task<Result> AddScheduleJobAsync(TaskScheduleModel m);

        /// <summary>
        /// 暂停定时任务
        /// </summary>
        /// <param name="jobGroup"></param>
        /// <param name="jobName"></param>
        /// <returns></returns>
        Task<Result> StopScheduleJobAsync(string jobGroup, string jobName);

        /// <summary>
        /// 恢复定时任务
        /// </summary>
        /// <param name="jobGroup"></param>
        /// <param name="jobName"></param>
        /// <returns></returns>
        Task<Result> RunScheduleJobAsync(TaskScheduleModel m);
    }

　　infrastructure里实现IJobCenter

　　记得引入quartz的nuget

　　代码如下：

/// <summary>
    /// 任务调度中心
    /// </summary>
    public class JobCenter:IJobCenter

        public static async Task<IScheduler> GetSchedulerAsync()

                IScheduler sched = await schedf.GetScheduler();
                return sched;
            }
        }

　　写一个JobServiceExtensions拓展，其中里面有一个AddJobSerivce，用于在startup里添加启动服务

　　技术分享图片

　　这个拓展的主要作用是：程序启动，自动查询我的任务调度管理表，查询里面的状态是开启中的任务，并将其添加到定时任务中

　　表结构大致如下：

　　技术分享图片

　　　这里我们主要注意任务组和任务名，这两个何在一起，能顶一个唯一的任务，后面我们会在httpjob里根据不同的的任务组和任务名

　　　区分他们要执行的不同的逻辑

　　技术分享图片

　　代码很简单：如下

public class HttpJob : IJob
    {
        
        /// <summary>
        /// 通过group和name判断是要执行哪个任务  具体（任务执行逻辑）业务逻辑写后面
        /// </summary>
        /// <param name="context"></param>
        /// <returns></returns>
        public async Task Execute(IJobExecutionContext context)
        {
            await Task.Run(() =>
            {
                var name = context.JobDetail.Key.Name;
                var group = context.JobDetail.Key.Group;
                if (group=="xx1"&&name=="xx2")
                {
                    //do something
                }

                if (group == "xx2" && name == "xx3")
                {
                    //do something also
                }
                Log4Net.Info($"执行任务_Name:{name}_Grop:{group}");
            });
        }
    }

　　在domain里新增ITaskService接口，如下

　　技术分享图片

　　代码如下：

public interface ITaskService
    {
        //获取任务列表
        Result GetTaskList();
        //添加任务
        Task<Result> AddTaskAsync(TaskScheduleModel model);
        //修改任务
        Task<Result> ModifyTaskAsync(TaskScheduleModel model);
        //删除任务
        Task<Result> DelTaskAsync(TaskScheduleModel model);
        //暂停任务
        Result PauseTask();
        //开启任务
        Result StartTask();
    }

　　在application 里实现这个接口

　　技术分享图片

　　代码如下：　　

public class TaskService : BaseService, ITaskService
    {
        private IJobCenter jobCenter = ServiceCollectionExtension.Get<IJobCenter>();

　　接着我们构建web页面

　　在website里创建taskinfo控制器

　　技术分享图片

　　代码很简单只是做了一个跳转

　　技术分享图片

　　创建视图

　　技术分享图片

　　代码如下：

　　之后效果就出来了

　　这个table会调用一个webapi接口获取数据

　　技术分享图片

　　这个webapi里我们直接调用我们改才ITaskService里分装的方法

　　技术分享图片

　　这里代码如下：

#region 计划任务模块
        [HttpPost]
        public Result GetTaskList()
        {
            return _taskService.GetTaskList();

        [HttpPost]
        public async Task<Result> AddTaskAsync([FromBody]TaskScheduleModel model)
        {
            if (model != null && !string.IsNullOrEmpty(model.Id)&&!model.Id.Equals("-1"))
            {
                return await _taskService.ModifyTaskAsync(model);
            }
