Axon message receives but event handler not call.
I am trying to implement the event sourcing in both the side with tow different queue. My First Queue is test and the Second one is testdemo
I have two separate application running on the same server.
- User Management
- Wallet Management
I have implemented the event sourcing from User Management to wallet management. and it is working fine.
Now I am trying to implement the wallet management to UserManagement, Means that When I will publish the event from the wallet management ( Producer ) and ( Consume ) the user management application. So the event is received but event handler is not called.
Following is my application code. Please help me to figure out what I will be missing.
