Analysis of the principle of timing task scheduling for Taskun Scheduler framework

Taskun Scheduler is an open source timing task scheduling framework written in Java.It provides a simple and powerful way to schedule and perform timing tasks, enabling developers to easily manage various timing tasks. The design concept of this framework is based on the mechanism of triggering events and executors.Each timing task consists of a trigger event and an executor.The trigger event defines the rules of when the task is triggered, and the execution processor defines the specific operation to be performed after the task is triggered. Taskun Scheduler supports a variety of types of triggers, such as simple trigger events, fixed rate trigger events, and fixed delay trigger events.The simple trigger event specifies the start time and end time of the task, and the trigger time interval.The fixed rate trigger an event specifies the start time and end time of the task, and the frequency of trigger.The fixed delay trigger event specifies the start time and end time of the task, and the delay time triggered. Each trigger event requires a processor to perform specific task operations.The executor must implement the Taskun Handler interface and implement the handle () method in it.In the Handle () method, developers can write the logic of tasks, including data processing, business logic, etc. Below is a simple Java code example to demonstrate how to use the Taskun Scheduler framework to create and perform a timing task: import io.github.biezhi.scheduler.Task; import io.github.biezhi.scheduler.TaskContext; import io.github.biezhi.scheduler.annotation.Cron; import io.github.biezhi.scheduler.annotation.EnableTask; import io.github.biezhi.scheduler.annotation.FixedDelay; import io.github.biezhi.scheduler.annotation.FixedRate; @EnableTask public class MyTask implements Task { // Simply trigger an event, execute every one minute every 1 minute @Cron("0 0/1 * * * ?") public void simpleTrigger(TaskContext context){ // Execute specific task logic System.out.println("Executing simpleTrigger task..."); } // The fixed rate trigger the event, executes every 5 seconds every 5 seconds @FixedRate(5000) public void fixedRateTrigger(TaskContext context){ // Execute specific task logic System.out.println("Executing fixedRateTrigger task..."); } // Fixed delay triggering event, delay for 10 seconds after the task is completed for 10 seconds to execute the next task @FixedDelay(10000) public void fixedDelayTrigger(TaskContext context){ // Execute specific task logic System.out.println("Executing fixedDelayTrigger task..."); } } public class Application { public static void main(String[] args) { Taskun.scheduler() .scan ("com.example.tasks") // Scanning task package .init () // Initialization task .start (); // Start the task scheduling } } In the above code, we created a MyTask class that implemented the TASK interface and defined three timing task methods, using different trigger event annotations.In the Application class, we use taskun.scheduler () to create a Taskun scheduler instance, and specify the task package to scan through the scan () method.Then initialize the task through the init () method, and finally start the task scheduling through the start () method. To sum up, the Taskun Scheduler framework can schedule and perform timing tasks by providing a simple and powerful way.Developers can achieve specific timing task logic by defining trigger events and executing processors.The framework is easy to use and expand, which can meet the dispatching needs of various timing tasks.
