hangfire定时任务 方法未定义
废话少说,直接上代码:
/// <summary> /// 开启定时联动定时任务 /// </summary> public void StartTimingTouchLinkAsync() { string recurringJobId = "设备联动定时执行"; string cronStr = "*/5 * * * * *"; RecurringJob.AddOrUpdate(recurringJobId,this.TimingTouchLinkAsync(), cronStr, TimeZoneInfo.Local); } /// <summary> /// 定时触发(每5秒) 联动触发(从关系库获取数据) /// </summary> /// <returns></returns> [UnitOfWork] public virtual async Task TimingTouchLinkAsync() { /***省略部分代码 ***/ var isMeet = await IsMeetCondition(conditionSymbol, conditionValue, intimeValue); /***省略部分代码 ***/ //触发执行联动 await this.DoLinkAsync(currentLinkId); /***省略部分代码 ***/ }
定时任务执行结果:
System.InvalidOperationException: Recurring job can't be scheduled, see inner exception for details. ---> Hangfire.Common.JobLoadException: Could not load the job. See inner exception for the details. ---> System.InvalidOperationException: The type `Awing.IBMS.Application.Business.LinkAppService` does not contain a method with signature `TimingTouchLinkAsync()` at Hangfire.Storage.InvocationData.DeserializeJob() --- End of inner exception stack trace --- at Hangfire.Storage.InvocationData.DeserializeJob() at Hangfire.RecurringJobEntity..ctor(String recurringJobId, IDictionary`2 recurringJob, ITimeZoneResolver timeZoneResolver, DateTime now) --- End of inner exception stack trace --- at Hangfire.Server.RecurringJobScheduler.ScheduleRecurringJob(BackgroundProcessContext context, IStorageConnection connection, String recurringJobId, RecurringJobEntity recurringJob, DateTime now)
原因分析:
明明有TimingTouchLinkAsync()方法,错误提示却还是不存在该方法,应该是方法中出现了错误。
因为TimingTouchLinkAsync()方法中同步方法、异步方法并存,故该方法可能出现同步异步执行时间混乱问题。
解决办法是为该方法。
1.方法添加属性 UnitOfWork
2.方法采用虚方法 virtual
3.注意方法中调用的其他方法也要采用上述2条。
