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!
