Fixing BeanNotOfRequiredTypeException on Spring proxy cast on a non-singleton bean?

Question

I\'m having an issue with pulling a Spring bean from an application context.

When I try;

InnerThread instance = (InnerThread) SpringContextFactory.g

One way to solve this issue is by extending the runnable interface and creating your own:

public interface MyInterface extends Runnable {
  // your own method declarations here
  void doSomething();
  ...
}

Then you should implement your interface instead of the runnable:

@Component("myInterface")
@Scope("prototype")
     public class MyInterfaceImpl implements MyInterface {

          // your own method declarations here
          public void doSomething(){
          ...
          }


          // implement run from Runnable Interface
          @Transactional
          public void run(){
                .....
          }

             ...
        }

This will work fine:

...
    MyInterface mynterface = SpringApplicationContext.getBean("myInterface", MyInterface.class);

    myInterface.doSomething();
  ExecutorService executor = Executors.newSingleThreadExecutor();
    executor.submit(myInterface);
...
