在上一篇绪中,已经介绍了整个项目的情况下了,接下来就是开始一步步做起来了。
首先:先整个我们的Job任务表,以及Job执行日志表。SQL如下:
1 drop table if exists job_info; 2 create table job_info 3 ( 4 id int not null AUTO_INCREMENT comment '主键', 5 job_name varchar(150) null default null comment '任务名称', 6 job_assembly varchar(200) null default null comment '执行的方式的dll名称', 7 job_class varchar(300) null default null comment '执行的方法类', 8 job_corn varchar(100) null default null comment '执行任务的corn表达式', 9 job_type int not null default 1 comment '任务类型,默认为1 简单,2 复杂', 10 job_execount int null default 0 comment '任务的执行总次数,0表示无限次', 11 job_starttime datetime null default null comment '任务开始时间', 12 job_state int null default 0 comment '任务的状态 0 准备中,1 执行中,2 暂定,3 停止,4 结束', 13 addtime TIMESTAMP null default CURRENT_TIMESTAMP comment '任务的创建时间', 14 PRIMARY KEY (`id`) 15 ); 16 drop table if exists job_log; 17 create table job_log 18 ( 19 id int not null AUTO_INCREMENT comment '主键', 20 job_name varchar(150) null default null comment '任务名称', 21 job_result varchar(200) null default null comment '执行的结果', 22 job_exception text null default null comment '执行任务的异常信息', 23 job_exetime int not null default 0 comment '执行耗时,单位ms', 24 job_exedate datetime null default 0 comment '任务的执行的日期时间', 25 job_exestate int null default 0 comment '执行结果 0 正常,1 异常', 26 addtime TIMESTAMP null default CURRENT_TIMESTAMP comment '任务的执行时间', 27 PRIMARY KEY (`id`) 28 );
相关实体类与操作方法,如下:
1 /// <summary> 2 /// Job信息表 3 /// </summary> 4 public class Job_Info : BaseEntity 5 { 6 private int _id = 0; 7 private string _job_name; 8 private string _job_assembly; 9 private string _job_class; 10 private string _job_corn; 11 private int _job_type = 1; 12 private int _job_execount = 0; 13 private DateTime _job_starttime; 14 private int _job_state = 0; 15 private DateTime _addtime; 16 17 /// <summary> 18 /// 主键 19 /// </summary> 20 public int Id { get => _id; set => _id = value; } 21 /// <summary> 22 /// 任务名称 23 /// </summary> 24 public string Job_name { get => _job_name; set => _job_name = value; } 25 /// <summary> 26 /// 执行的方式的dll名称 27 /// </summary> 28 public string Job_assembly { get => _job_assembly; set => _job_assembly = value; } 29 /// <summary> 30 /// 执行的方法类 31 /// </summary> 32 public string Job_class { get => _job_class; set => _job_class = value; } 33 /// <summary> 34 /// 执行任务的corn表达式 35 /// </summary> 36 public string Job_corn { get => _job_corn; set => _job_corn = value; } 37 /// <summary> 38 /// 任务类型,默认为1 简单,2 复杂 39 /// </summary> 40 public int Job_type { get => _job_type; set => _job_type = value; } 41 /// <summary> 42 /// 任务的执行总次数,0表示无限次 43 /// </summary> 44 public int Job_execount { get => _job_execount; set => _job_execount = value; } 45 /// <summary> 46 /// 任务开始时间 47 /// </summary> 48 public DateTime Job_starttime { get => _job_starttime; set => _job_starttime = value; } 49 /// <summary> 50 /// 任务的状态 0 准备中,1 执行中,2 暂定,3 停止,4 结束 51 /// </summary> 52 public int Job_state { get => _job_state; set => _job_state = value; } 53 /// <summary> 54 /// 任务的创建时间 55 /// </summary> 56 public DateTime Addtime { get => _addtime; set => _addtime = value; } 57 58 }

这些都是数据库的基本操作,我就直接贴出来了。为了规范,我们就定了一个接口,供所有Job任务来实际业务,接口很简单,具体如下:
/// <summary> /// 基Job /// </summary> public interface IJob { /// <summary> /// 执行任务 /// </summary> bool Exceute(); }
好了,下面我们就开始我们的Job托管器-Window Server。为了方便,我就使用Topshelf,因为创建JobManage.Service这个项目时,一定要选择Console项目(我一开始就直接使用了Service项目,然后一直运行不起来)。
那现在来创建一个JobServer类,实现ServiceControl, ServiceSuspend 两大接口的方法,在服务启动的时候,实例化Schedule,然后加入检查Job的Job任务,定期增加或删除Schedule里的Job。
实现如下:
public bool Start(HostControl hostControl) { if (JobConfig.factory == null) { JobConfig.factory = new StdSchedulerFactory(); JobConfig.scheduler = JobConfig.factory.GetScheduler(); JobConfig.scheduler.Start(); //创建循环Job IJobDetail job = JobBuilder.Create<LoopJob>().WithIdentity("LoopJob", "group1").Build(); ITrigger trigger = TriggerBuilder.Create() .WithIdentity("LoopJobtrigger", "group1") .WithCronSchedule("0 0/5 * * * ?") //30分种执行一次 .StartAt(new DateTimeOffset(DateTime.Now.AddSeconds(5))) .Build(); JobConfig.scheduler.ScheduleJob(job, trigger); } else { JobConfig.scheduler.Start(); } return true; } public bool Stop(HostControl hostControl) { if (JobConfig.factory != null) { JobConfig.scheduler.Shutdown(false); JobConfig.factory = null; JobConfig.scheduler = null; } return true; }
好了,这一节就先到这,下面的我喝杯茶再来~
