Spring如何同步两个微服务

Question

I have two microservices. Service #1 puts a certain object in the queue (a table in the database) that needs to be processed. After that, in service #2 , the sheduler takes new records from the queue every few seconds and processes them, and then saves the result as json to the database. The question is, how do I notify service #1 about the result of processing?

Answer 1

You can achieve this using any messaging brokers activeMq or rabbitMq. Please refer: https://spring.io/guides/gs/messaging-rabbitmq/ Please make use of a rabbitmq receiver to fetch the notification and trigger the processing on you service 1 appropriately

Answer 2

You can set up Kafka for your microservice communication. For notifying service #1 you can send an event from service #2 through Kafka. Suppose, from service #2 you'll send an event named "PROCESSING_DONE" and service #1 will listen to this event and can do the further processing.

This all will take place in realtime.
