Camel Example Spring Boot

This example shows how to work with a simple Apache Camel application using Spring Boot.

The example generates messages using timer trigger, writes them to standard output.

Camel routes

The Camel route is located in the MyCamelRouter class. In this class the route starts from a timer, that triggers every 2nd second and calls a Spring Bean MyBean which returns a message, that is routed to a stream endpoint which writes to standard output.

Using Camel components

Apache Camel provides 200+ components which you can use to integrate and route messages between many systems and data formats. To use any of these Camel components, add the component as a dependency to your project.

How to run

You can run this example using

mvn spring-boot:run

To get health check

To show a summary of spring boot health check

curl -XGET -s http://localhost:8080/actuator/health

And you can see some info details as well

curl -XGET -s http://localhost:8080/actuator/info

See the application.properties to control what information to present in actuator.

Camel Developer Console

This application includes camel-console-starter which is a basic developer console that is accessible as a Spring Boot actuator endpoint via:

curl -XGET -s http://localhost:8080/actuator/camel

For example to get route information:

curl -XGET -s http://localhost:8080/actuator/camel/routes

Camel CLI

This application is integrated with the Camel CLI via the camel-cli-connector-starter dependency (see pom.xml). This allows to use the Camel CLI to manage this application, such as:

$mvn spring-boot:run

And then use the CLI to see status:

$camel get
  PID   NAME                          CAMEL   PLATFORM            READY  STATUS   AGE  TOTAL  FAILED  INFLIGHT  SINCE-LAST
 86000  sample.camel.MyCamelApplica…  3.19.0  Spring Boot v2.7.3   1/1   Running  11s      5       0         0          0s
