push a dynamic message in Scheduler websocket using spring boot using stomp - spring-boot

Question

I try to make a chatbot using springboot (websocket), i want to know if it's possible to push a dynamic message in Scheduler, and i need some help, i'can't fugure it out.
I want to push the message in the Scheduler Configure how could i do that:
#EnableScheduling
#Configuration
public class SchedulerConfig {
#Autowired
SimpMessagingTemplate template;
#Scheduled(fixedDelay = 3000)
public void sendAdhocMessages() {
template.convertAndSend("/topic/user", new UserResponse("Fixed Delay Scheduler"));
}
}
in the sendAdhocMessages method i want to pass a message that will be displayed in an html page. in the Official doc it's impossible to pass a parameter to a method which is annotated by #Scheduled, is there any methd to do that?

Answer 1

The official documentation contains a hint to, how you could pass values to the scheduled method. Maybe you could provide a bean that acts as a message provider. In the scheduler class you autowire the message provider and request the messages.
A short code example:
#Componet
public class MessageProvider {
private String message;
// getter and setter ...
}
In the scheduler you could use the message provider like following:
#EnableScheduling
#Configuration
public class SchedulerConfig {
#Autowired
SimpMessagingTemplate template;
#Autowired
MessageProvider messageProvider;
#Scheduled(fixedDelay = 3000)
public void sendAdhocMessages() {
String currentMessage = messageProvider.getMessage();
template.convertAndSend("/topic/user", new UserResponse(currentMessage));
}
}
