获取Quartz.NET 2.0中的所有工作

Question

我在服务器上设置了我的AdoJobStore,我的所有工作都运行得很好.现在我正在编写一个远程客户端来管理我的所有工作.

调度新作业非常简单,但我似乎无法检索2.0版中的现有作业列表.我找到的所有资源都做了类似的事情.

var groups = sched.JobGroupNames;
for (int i = 0; i < groups.Length; i++)
{
    string[] names = sched.GetJobNames(groups[i]);
    for (int j = 0; j < names.Length; j++)
    {
        var currentJob = sched.GetJobDetail(names[j], groups[i]);
    }
}

我面临的问题是GetJobNames已被删除,并且查看源代码,已被移动到JobStoreCpport继承的基类JobStoreSupport.然而,该方法已被标记为受保护,因此无法从外部访问.

如何在2.0中检索工作列表？

您可以使用获取执行作业的列表:

var executingJobs = sched.GetCurrentlyExecutingJobs();
foreach (var job in executingJobs)
{
    // Console.WriteLine(job.JobDetail.Key);
}

或者获取有关预定作业的所有信息(示例控制台应用程序):

private static void GetAllJobs(IScheduler scheduler)
{
    IList<string> jobGroups = scheduler.GetJobGroupNames();
    // IList<string> triggerGroups = scheduler.GetTriggerGroupNames();

    foreach (string group in jobGroups)
    {
        var groupMatcher = GroupMatcher<JobKey>.GroupContains(group);
        var jobKeys = scheduler.GetJobKeys(groupMatcher);
        foreach (var jobKey in jobKeys)
        {
            var detail = scheduler.GetJobDetail(jobKey);
            var triggers = scheduler.GetTriggersOfJob(jobKey);
            foreach (ITrigger trigger in triggers)
            {
                Console.WriteLine(group);
                Console.WriteLine(jobKey.Name);
                Console.WriteLine(detail.Description);
                Console.WriteLine(trigger.Key.Name);
                Console.WriteLine(trigger.Key.Group);
                Console.WriteLine(trigger.GetType().Name);
                Console.WriteLine(scheduler.GetTriggerState(trigger.Key));
                DateTimeOffset? nextFireTime = trigger.GetNextFireTimeUtc();
                if (nextFireTime.HasValue)
                {
                    Console.WriteLine(nextFireTime.Value.LocalDateTime.ToString());
                }

                DateTimeOffset? previousFireTime = trigger.GetPreviousFireTimeUtc();
                if (previousFireTime.HasValue)
                {
                    Console.WriteLine(previousFireTime.Value.LocalDateTime.ToString());
                }
            }
        }
    } 
}

我已经使用了这里找到的代码.

更新:

如果有人感兴趣,可以从我的GitHub 存储库下载示例代码.

有人问如何获得完成的工作清单.
我不认为有一个简单的方法.
想到的唯一选择是使用作业(或触发器)监听器.

我已经在github 上传了一个示例,我的主程序可以接收已完成作业的事件.

如果要获取重复间隔，重复计数等，则将ITrigger强制转换为ISimpleTrigger

private void LogInfo(IScheduler scheduler) 
{
    log.Info(string.Format("\n\n{0}\n", Scheduler.GetMetaData().GetSummary()));

    var jobGroups = scheduler.GetJobGroupNames();
    var builder = new StringBuilder().AppendLine().AppendLine();

    foreach (var group in jobGroups)
    {
        var groupMatcher = GroupMatcher<JobKey>.GroupContains(group);
        var jobKeys = scheduler.GetJobKeys(groupMatcher);

        foreach (var jobKey in jobKeys)
        {
            var detail = scheduler.GetJobDetail(jobKey);
            var triggers = scheduler.GetTriggersOfJob(jobKey);

            foreach (ITrigger trigger in triggers)
            {
                builder.AppendLine(string.Format("Job: {0}", jobKey.Name));
                builder.AppendLine(string.Format("Description: {0}", detail.Description));
                var nextFireTime = trigger.GetNextFireTimeUtc();
                if (nextFireTime.HasValue)
                {
                    builder.AppendLine(string.Format("Next fires: {0}", nextFireTime.Value.LocalDateTime));
                }
                var previousFireTime = trigger.GetPreviousFireTimeUtc();
                if (previousFireTime.HasValue)
                {
                    builder.AppendLine(string.Format("Previously fired: {0}", previousFireTime.Value.LocalDateTime));
                }
                var simpleTrigger = trigger as ISimpleTrigger;
                if (simpleTrigger != null)
                {
                    builder.AppendLine(string.Format("Repeat Interval: {0}", simpleTrigger.RepeatInterval));
                }
                builder.AppendLine();
            }
        }
    }

    builder.AppendLine().AppendLine();
    log.Info(builder.ToString); 
}

从Quartz.NET 2.2.1版本开始，您可以使用GroupMatcher<>.AnyGroup()，这里实现为以下扩展方法IScheduler：

public static List<IJobDetail> GetJobs(this IScheduler scheduler)
{
    List<IJobDetail> jobs = new List<IJobDetail>();

    foreach (JobKey jobKey in scheduler.GetJobKeys(GroupMatcher<JobKey>.AnyGroup()))
    {
        jobs.Add(scheduler.GetJobDetail(jobKey));
    }

    return jobs;
}

这将为您列出IJobDetail每个预定作业的列表。
