I have 2 classes
1) ScheduledTasks.java
2) UserNotificationServiceImpl.java

I have @Autowired a class in both the above classes.

I have set a Set<String> private member variable in ScheduledTasks into the @Autowired reference(userDao) whcih I later want to access later from UserNotificationDAO of UserNotificationServiceImpl.
But I am not able to.

Firstly I thought, may be spring boot is not creating a singleton instance.
I printed the object. I assume, that it prints the memory address by default if toString method is not overriden.

I found both the memory address to be the same.

I set a Set<String> in ScheduledTasks into userDao and which I can see that it has been properly set in ScheduedTasks itself before I proceeded.

You can have a look at the logs




*************Inside ScheduledTasks.java ***********************************
Notification: *** Inside sendNotificationForOrdersOnHold()
Notification: *** Executing Query as select oos2.orderitemnumber||','||oon2.event_id ORDER_EVENT from om_order_notifications1 oon2, om_order_stage oos2  where (oon2.orderitemnumber, oon2.user_notification_date) in (SELECT oon.orderitemnumber, MAX(oon.user_notification_date) FROM om_order_notifications1 oon, om_order_stage oos WHERE oon.orderitemnumber = oos.orderitemnumber  AND UPPER(oos.orderstagestatus) LIKE('%HOLD%') AND oos.stage_flag = 'Y' AND oon.NOTIFICATION_ID='14' GROUP BY oon.orderitemnumber HAVING MAX(oon.user_notification_date) + (select nvl(min(VALUE),30) from OM_MASTER_DATA WHERE KEY='on_hold_day_span') < sysdate AND MIN(oon.user_notification_date) + (select nvl(min(VALUE),365) from OM_MASTER_DATA WHERE KEY='when_to_cancel_order') > sysdate)  and oon2.ORDERITEMNUMBER=oos2.ORDERITEMNUMBER  and oos2.stage_flag='Y'  AND oon2.NOTIFICATION_ID='14' and oon2.event_id like '%1006'
Notification: *** Orders to be notified = [160304995,20160624.10598.1006]
Notification: *** userDAO in ScheduledTasks = net.colt.notifications.DAO.impl.UserNotificationDAOImpl@72061775

//         userDao.setOrdersOnHold(ordersOnHold);
Notification: *** Orders On Hold set in UserDAO = [160304995]


********* Inside UserNotificationServiceImpl ***************************
Here I have @Autowired UserNotificationDAO and when I invoke getOrdersOnHold, I get an empty Set.

Notification: *** ###################################### userNotificationDAO.getOrdersOnHold=[]
Notification: *** UserNotificationDAO in UserNotificationServiceImpl = net.colt.notifications.DAO.impl.UserNotificationDAOImpl@72061775


Both the objects are same.

But I do not get the set, when I try to access it using the other reference. (As you can see getOrdersOnHold gives me an empty Set.

Any help in this regard is appreciated.

Regards
Yogesh
