This example demonstrates how you can use Apache Camel with Spring Boot based on a fabric8 Java base image
The quickstart uses Spring Boot to configure a little application that includes a Camel route that triggeres a message every 5th second, and routes the message to a log.
The example can be built with
mvn clean install
The example can be run locally using the following Maven goal:
mvn spring-boot:run
Note, you'll need to be able to connect to Kafka (we use the new-consumer impl, so don't need to directly access Zookeeper) so if you run locally make sure kafka is available at kafka:9092 or change the from("kafka:xxxx)" part of the route.
mvn clean package -Pf8-build docker:build
docker run -it --rm fabric8/ticket-monster-admin-camel:2.0-SNAPSHOT
Since we're relying on eventual consistency to make the booking/ticket from the Orders context and the Admin context consistent, we will need to relax the assumption that all bookings and tickets originate within a single database and thus relax any foreign key constraints around ticket/bookings. To do this, log into the admin mysql instance and:
mysql> show create table Ticket;
mysql> alter table Ticket drop foreign key FKolbt9u28gyshci6ek9ep0rl5d;
This will allow us to insert Ticket record without there being a Booking record yet as the CDC process will eventually update the rows for Booking.
You can find more details about running this quickstart on the website. This also includes instructions how to change the Docker image user and registry.
