Spring Boot Axon CQRS Docker Example

This is a simple example how the Axon Framework can be used with Spring Boot to implement CQRS and Event Sourcing. It's about peanuts!

Run it

Just run Docker Compose to build and start the containers.

docker-compose up --build

Test it

The scenario is simple: place a bowl on a table, fill it with some peanuts and don't let them go bad.

The command service runs on http://localhost:8081, the query service in http://localhost:8082.

To put a new bowl on the table just do

POST http://localhost:8081/bowl

The result contains a UUID which identifies the bowl for further actions. Let's fill the bowl with some peanuts

PUT http://localhost:8081/bowl/<uuid>/peanuts 

{"amount" : "100"}

The bowl should contain 100 peanuts now, let's check this

GET http://localhost:8082/bowl/<uuid>/peanuts

Yummy! We should be able to take some peanuts out of the bowl now

DELETE http://localhost:8081/bowl/<uuid>/peanuts

{"amount" : "10"}

Let's see how many peanuts are left

GET http://localhost:8082/bowl/<uuid>/peanuts

Oh, only 90...

Enjoy your meal!
