Quartz.Net系列（三）：解读Quartz.Net源码领略设计模式在其中的应用

1.Builder（建造者）模式

JobBuilder

 

 

 DateBuilder

 

 

 其他的Builder（TriggerBuilder、SchedulerBuilder等）

 

 

 

2.抽象工厂模式

ISchedulerFactory

DirectSchedulerFactory StdSchedulerFactory

 

 

IScheduler

StdScheduler RemoteScheduler[proxy]

 

 

3.IOC模式、可插拔式设计

//如果你没有自定义的loadHelper，那么就使用SimpleTypeLoadHelper
loadHelper = ObjectUtils.InstantiateType(typeLoadHelperType ?? typeof(SimpleTypeLoadHelper));

 

 

4.AOP模式[切面编程]

scheduler.ListenerManager.AddJobListener(new CustomJobListener(),GroupMatcher.AnyGroup());

public class CustomJobListener : IJobListener
{
    public string Name => "CustomJobListener";

    /// 

    /// 执行否决
    /// 
    /// 
    /// 
    /// 
    public async Task JobExecutionVetoed(IJobExecutionContext context, CancellationToken cancellationToken = default)
    {
        await Task.Factory.StartNew(() =>
        {
            Console.WriteLine("JobExecutionVetoed");
        });

    }
    /// 

    /// 待执行
    /// 
    /// 
    /// 
    /// 
    public async Task JobToBeExecuted(IJobExecutionContext context, CancellationToken cancellationToken = default)
    {
        await Task.Factory.StartNew(() =>
        {
            Console.WriteLine("JobToBeExecuted");
        });
    }

    /// 

    /// 已执行
    /// 
    /// 
    /// 
    /// 
    /// 
    public async Task JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException, CancellationToken cancellationToken = default)
    {
        await Task.Factory.StartNew(() =>
        {
            Console.WriteLine("JobWasExecuted");
        });
    }
}
