| == Spring Boot Example with Camel REST DSL and Platform HTTP |
| |
| === Introduction |
| |
| This example illustrates how to use https://projects.spring.io/spring-boot/[Spring Boot] with http://camel.apache.org[Camel]. It provides a simple REST service that is created with http://camel.apache.org/rest-dsl.html[Camel REST DSL] and https://camel.apache.org/components/3.18.x/platform-http-component.html[platform-http]. |
| |
| The project uses the `camel-spring-boot-starter` dependency, a Spring Boot starter dependency for Camel that simplifies the Maven configuration. |
| |
| The project also uses `camel-servlet-starter` component as the implementation for platform-http-engine. |
| |
| === Build |
| |
| You can build this example using: |
| |
| $ mvn package |
| |
| === Run |
| |
| You can run this example using: |
| |
| $ mvn spring-boot:run |
| |
| You should see the following output when the application is launched: |
| |
