Spring Kafka - how to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Kafka is an asynchronous messaging queuing system, but when you have a case in your project that you need to have the result immediately from another service you can do that quite easily. Kafka from the client side produces a message to the server side, then waiting for the server to return back the message exactly what the client wants. It’s identified in the kafka header request named KafkaHeaders.CORRELATION_ID and a topic where the server should send. If the server side produces the same correlation id to the same topic in the request, then the client side will catch that message as its reply. Although you can work with kafka from a different framework and language other than Java and Spring. Here’s in this example i just specifically giving the example of sending and replying kafka messages using Spring Boot.

Reactive Spring Logo This is maybe a very simple task, but for those of you that may not be familiar with WebFlux found it difficult to create a Rest API that handles upload and download in Reactive spring application. Create the skeleton Spring project Create a new project, go to start.spring.io , on the dependencies section, add Spring Reactive Web. Generate and extract it into your desired project location. Instead of using spring-boot-starter-web, use spring-boot-starter-webflux instead in your pom.xml. Here’s the pom.xml for our Reactive Rest API project. Create our Rest controller Now that you have set to use WebFlux instead of the usual web, we have to change a little bit in the Controller class that handles the API endpoints.
