JarCastingManaged Task (MTask)
Background task is required for every enterprise projects.
Spring Framework support many kind of background tasks: Spring Scheduling, Spring Boot Quartz...
MTask is based on Spring Boot add new feature for monitoring and controlling on the fly.
- Add/remove Scheduling Task via Rest API (Spring Scheduling theo fixedrate hoặc cron)
- Stop/start scheduling task via API (Restful API)
- Change parameter's tasks via API (Restful API)
- Monitoring task by realtime log via Websocket
Step by step
More info in mtask-sample
1. Import maven library:
<dependency>
<groupId>com.github.tyrion9</groupId>
<artifactId>mtask-spring-boot-starter</artifactId>
<version>0.0.1</version>
</dependency>
2. Write a class extends MTask
HelloWorldMTask
public class HelloWorldMTask extends MTask {
private static final Logger log = LoggerFactory.getLogger(HelloWorldMTask.class);
@Override
public void run() {
log.info("Hello World");
mlog.log("Hello World"); // Websocket Log
}
}
ComplexMTask: declare parameters, autowired bean to use
public class ComplexMTask extends MTask {
private static final Logger log = LoggerFactory.getLogger(ComplexMTask.class);
@Autowired
private GreetingService greetingService;
@MTaskParam("name")
private String name;
@Override
public void run() {
String greetingMsg = greetingService.greeting(name);
log.info(greetingMsg);
mlog.log(greetingMsg); // websocket log
}
}
3. declare mtask configuration (yaml)
- code: helloworld
scheduled:
period: 1000
name: Hello World MTask
className: sample.sample1.HelloWorldMTask
autoStart: true
- code: complex
scheduled:
period: 1000
name: Autowired Param MTask
className: sample.sample2.ComplexMTask
params:
name: HoaiPN
autoStart: true
4. Run
@SpringBootApplication
@ComponentScan(basePackages = {"com.github.tyrion9.mtask", "sample"})
public class SampleApplication {
public static void main(String[] args) {
SpringApplication.run(SampleApplication.class, args);
}
}
5. Monitor application
Client Tool is not developed yet, so use other tool for management:
- Postman call rest API for management (stop/start/change parameters)
- Simple Websocket Client - Chrome Plugin - to check log realtime
Real time log 
API list/stop/start/change parameters
curl -X GET http://localhost:8080/api
curl -X POST http://localhost:8080/api/helloworld/stop
curl -X POST http://localhost:8080/api/helloworld/start
