Summary and advanced 1. Introduction to districtricron Distribicron is a Java -based open source framework, which aims to simplify the development of Java libraries.It provides a powerful and flexible API to help you manage and schedule various tasks and get the best performance.Distribicron's goal is to provide priority and parallel processing of different types of tasks in a simple way, so that your code is more readable and maintained. 2. Installation and configuration Before starting, you need to download and install Maven, because we will use Maven to build projects and management dependencies in this tutorial.Make sure you have set the global configuration of the Java environment variables and MAVEN correctly. 3. Write your first library 3.1 Create a Maven project First of all, by executing the following Maven command, create a new Maven project under the directory you choose: mvn archetype:generate -DgroupId=com.example -DartifactId=my-library -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false This will generate a Maven project called "My-Library". 3.2 Add Districron dependencies Open the "POM.XML" file and add the following code to the label in the `Dependenncies>` tag to introduce the dependencies of distribution: <dependencies> ... <dependency> <groupId>com.districron</groupId> <artifactId>districron-core</artifactId> <version>1.0.0</version> </dependency> ... </dependencies> Save and turn off the "POM.XML" file, and then execute the `mvn install` command to install dependencies. 3.3 Definition task scheduling Create a new Java file, such as "myscheduler.java", and write the code for the task scheduling in it.The following is a simple example: import com.districron.scheduler.Scheduler; import com.districron.scheduler.Job; import com.districron.scheduler.JobResult; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class MyScheduler { private static final Logger LOGGER = LoggerFactory.getLogger(MyScheduler.class); public static void main(String[] args) { Scheduler scheduler = new Scheduler(); // Create a new job Job job = new Job("myJob", () -> { Logger.info ("Executive task ..."); // Here is the processing logic of the task return new JobResult(JobResult.Status.SUCCESS); }); // Add the job to the scheduler scheduler.schedule(job); // Start the scheduler and run the task scheduler.start(); // Add some delay time here try { Thread.sleep(5000); } catch (InterruptedException e) { Logger.error ("Thread interruption abnormal", e); } // Turn off the scheduler scheduler.stop(); } } This example shows how to define a simple task scheduler using Districron.It created a task called "Myjob" and printed a log when the task was executed.You can define more tasks according to your needs. 4. Use Districron API 4.1 Create a job In the previous example, we used the `job` class to create a new task.The `Job` class accepts a unique identifier and a` Runnable` object as a parameter to define tasks.You can add the required parameters as needed. 4.2 Set the execution parameter of job You can set the execution parameters of the task through the method of the `Job` Setparameter ()` method.For example, send some data or configuration to the task. 4.3 Define the logic of JOB The processing logic of the definition task is completed by implementing the `run ()` method of the `runnable` interface.In this method, you can write the code logic required for the task to complete the specific function. 4.4 Run the task and get the result Call the `Start () method of the` Scheduler` class to start the task scheduler and use the `jobsult` object to obtain the execution result of the task. 5. Advanced function and configuration Districron provides some advanced functions and configuration options to meet your different needs.You can check the official documentation of Districron to get more details and example code. 5.1 parallel task scheduling Districron supports multiple tasks in parallel.You can configure the parallel execution of the task by setting a parallelity option on the scheduler. 5.2 Asynchronous task processing Distribicron also supports asynchronous execution tasks.You can use asynchronous mechanisms (such as CompletableFuture) in the task processing logic to achieve asynchronous operations. 5.3 The fault tolerance mechanism of task scheduling Districron provides some fault tolerance mechanisms to ensure the reliable execution of the task.You can set options such as the number of retry and delay time for the task to deal with possible failures. 5.4 Custom task priority Distribicron allows you to set different priorities for different tasks.This can be configured by the priority options on the scheduling. 6. Summary and advanced Through this tutorial, you have learned how to use the Districron framework to quickly develop the Java library development.You can further explore the documentation and example code of Districron to discover more functions and best practices.I wish you an excellent Java class library!
