spring autowiring not working from a non-spring managed class

Question

I have a class (Class ABC) that's instantiated by calling the constructor. Class ABC in turn has a helper class (Class XYZ) injected using auto-wired.

Ours is a Spring MVC based application and I don't see any exception while server start-up.

But I still see Class XYZ coming as null. Is it because of the fact that Class ABC is not instantiated by Spring Container?

In such scenarios, how do i make use of auto-wiring?

Thanks.

You can use this way to use spring bean in non-spring bean class

import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component;  @Component public class ApplicationContextUtils implements ApplicationContextAware {             private static ApplicationContext ctx;             @Override       public void setApplicationContext(ApplicationContext appContext) {         ctx = appContext;       }             public static ApplicationContext getApplicationContext() {         return ctx;       } } 

now you can get the applicationcontext object by getApplicationContext() this method.

from applicationcontext you can get spring bean objects like this:

ApplicationContext appCtx = ApplicationContextUtils.getApplicationContext(); String strFromContext = appCtx.getBean(beanName, String.class);
