SpringBoot - How can I call a controller from a MQ message listener - spring-boot

Question

I have a JMS listener configured which receives messages from IBM MQ. Once there is a message in the MQ, I want to post the message to my rest controller.
MQ JMS Listener
public class MqMessageConsumer {
private Logger log = LoggerFactory.getLogger(MqMessageConsumer.class);
#JmsListener(destination = "${ibm.mq.queue-name}")
public void receiveMessage(String message) {
log.info("There is a message in the queue");
//invoke rest end point
log.info(message);
//invoke rest controller in case of MQ call.
}
}
Below is my RestController
#RequestMapping("/users")
public class UsersController {
Logger logger = LoggerFactory.getLogger(UsersController.class);
#PostMapping("/status/checkUser")
public String getStatus() {
return "details";
}
}
Any idea how the rest controller can be called from the MQ consumer class?

Answer 1

You can add a UsersService and use it in both the consumer and controller. In general we keep controller as thin as possible and put business logic in a service
Code can be something like
#Service
public class UsersService {
public String getStatus() {
return "details";
}
}
#Component
public class MqMessageConsumer {
#Autowired UsersService usersService;
#JmsListener(destination = "${ibm.mq.queue-name}")
public void receiveMessage(String message) {
usersService.getStatus();
}
}
#RequestMapping("/users")
public class UsersController {
#Autowired UsersService service;
#PostMapping("/status/checkUser")
public String getStatus() {
return service.getStatus();
}
}
