import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class ApplicationContextUtils implements ApplicationContextAware {

private static ApplicationContext ctx;

@Override
public void setApplicationContext(ApplicationContext appContext)
throws BeansException {
ctx = appContext;

}

public static ApplicationContext getApplicationContext() {
return ctx;
}

public static Object getBean(Class clazz){
return ctx.getBean(clazz);
}
}
