Autowiring Tasks sent to Spring TaskExecutor

Question

How can you have a class that implements Runnable and submitted to springs TaskExecutor autowired?

For example, I have a Task:

public class MyTask implem         


        

Answer 1

try

public class MyTask implements Runnable {
    private MyRepository myRepository;

    public MyTask(MyRepository myRepository) {
         this.myRepository = myRepository;
    }

    @Override
    public void run() {
        myRepository.doSomething();
    }
}

@Service
public class MyService {
    @Autowired private TaskExecutor taskExecutor;
    @Autowired private MyRepository myRepository;


    public void someMethod() {
        MyTask myTask = new MyTask(myRepository);
        taskExecutor.execute(myTask);
    }
}

or you can declare MyTask's scope = "prototype" and change MyService as

@Service
public class MyService {
    @Autowired private ApplicationContext ctx;

    public void someMethod() {
        MyTask myTask = ctx.getBean(MyTask.class);
        taskExecutor.execute(myTask);
    }
}
