Vert.x AMQP example

This example demonstrates a publish-subscribe integration pattern implemented using Vert.x Spring Boot AMQP client. This monolithic application is divided into two logical services which communicate via two queues created in an embedded Artemis broker.

Application workflow

Submitting message for processing

POST request > controller > messages manager > AMQP broker > uppercase processor > AMQP broker > messages manager

Receiving processed messages

GET request > controller > messages manager > controller > GET response

Usage

Start the application in one terminal window.

java -jar target/vertx-spring-boot-sample-amqp.jar

And access it in another.

First submit a couple of messages for processing.

echo "Hello, World" | http POST :8080
echo "Hello again" | http POST :8080

Then check the result.

http :8080

You should get something like the following.

HTTP/1.1 200 OK
Content-Type: text/event-stream;charset=UTF-8
transfer-encoding: chunked

data:HELLO, WORLD

data:HELLO AGAIN
