To run:
mvn clean spring-boot:run
This will start a REST service on port 8080 using the embedded servlet container, Undertow:
$ curl http://localhost:8080/camel/hello
Hello world!
Note that the default servlet path for Camel is /camel.
NB: Requires JDK 11 (for no good reason, other than I just wanted to test it out). So, ensure you're using JDK 11, e.g. with sdkman:
sdk install java 11.0.9.hs-adpt
sdk use java 11.0.9.hs-adpt
