Distribicron framework application practice: solve the pain points of the development of Java library development
Abstract: The Distribicron framework is a Java -based distributed task scheduling framework that aims to solve the pain point in the development of the Java library.This article will introduce the application practice of the DISTRICRON framework and provide relevant programming code and configuration description.
introduction:
During the development of the Java library, we often face some pain points, such as the complexity of the task scheduling, the performance bottleneck, and the task execution in the distributed environment.To solve these problems, the Distribicron framework came into being.This article will introduce the application practices of the Distribicron framework in detail to help developers better understand and use the framework.
1. Districron framework profile
The Distribicron framework is a Java -based distributed task scheduling framework, which aims to solve the complexity and performance bottleneck of task scheduling.It adopts the idea of distributed coordination to distribute the task to different nodes to improve the parallelism and scalability of the task.The Distribicron framework also provides visualized task monitoring and management interface to facilitate developers monitor and adjust task scheduling.
2. Districron framework application practice
2.1 Environmental preparation
Before starting application practice, we need to prepare the following environment:
-JDK 1.8 above version
- Apache Maven
-Zookeeper cluster
2.2 Installation and configuration of the Distribicron framework
First, we need to add the dependencies of the DISTRICRON framework to the project.In the pom.xml file of the project, add the following dependencies:
<dependency>
<groupId>io.districron</groupId>
<artifactId>districron-core</artifactId>
<version>1.0.0</version>
</dependency>
We need to configure the related parameters of the Distribicron framework.In the project's configuration file (such as Application.properties), add the following configuration information:
properties
# Distribise core configuration
districron.zookeeper.address=127.0.0.1:2181,127.0.0.2:2181,127.0.0.3:2181
districron.zookeeper.session.timeout=60000
districron.worker.thread.pool.size=20
# 任 definition
districron.job.package=com.example.jobs
#
districron.job.strategy=com.example.jobs.MyJobSchedulingStrategy
2.3 Development task scheduling code
Next, we need to write a task scheduling code.First of all, we need to create a task class that implements the `job` interface, such as:
package com.example.jobs;
import io.districron.api.annotations.Job;
@Job(name = "myJob", cronExpression = "0 0/10 * * * ?", concurrentExecutionDisallowed = true)
public class MyJob implements io.districron.api.Job {
public void execute() {
// Specific logic of executing tasks
System.out.println ("Perform myjob task!"););
}
}
Then, we can create a task scheduler class for registration and startup tasks, such as
package com.example;
import io.districron.client.DistricronClient;
import io.districron.client.JobScheduler;
public class Scheduler {
public static void main(String[] args) throws Exception {
DistricronClient districronClient = new DistricronClient("localhost:2181");
JobScheduler jobScheduler = districronClient.createJobScheduler("myScheduler", "com.example.jobs");
jobScheduler.start();
}
}
3. Run and manage task scheduling
After completing the development code, we can use the command` MVN CLEAN PACKAGE` to pack the project and deploy the generated jar file into a distributed environment.Then, run the following command to start the task scheduling in the command line:
bash
java -jar my-scheduler.jar
At the same time, the Districron framework provides visualized task monitoring and management interface.We can open the management interface in the browser by visiting the `http:// localhost: 8080` to check and manage the registered tasks.
in conclusion:
The Distribicron framework is a powerful tool to solve the pain point of the development of the Java library. It simplifies the complexity of task scheduling and provides performance optimization and distributed environmental support.This article introduces the application practice of the DISTRICRON framework and provides related programming code and configuration description. It hopes that developers can better understand and apply the framework to improve the efficiency and quality of the Java class library development.
