What is Camel Spring Boot and how do you configure routes as Spring beans?

camel-spring-boot auto-configures a CamelContext as a Spring bean and binds its lifecycle to the Spring ApplicationContext. Any class annotated with @Component that extends RouteBuilder is automatically discovered and added. The starter also exposes Camel properties under the camel.* namespace in application.properties.

// Route class:
@Component
public class InvoiceRoute extends RouteBuilder {
    @Value("${app.input-dir}") String inputDir;
    @Override
    public void configure() {
        from("file:" + inputDir + "?noop=true")
            .routeId("invoice-route")
            .to("direct:process");
    }
}

# application.properties
camel.springboot.name=MyApp
camel.springboot.routes-include-pattern=classpath:routes/*.yaml
app.input-dir=/data/invoices

In addition to Java DSL routes, camel-spring-boot supports YAML and XML DSL route definitions loaded from the classpath via camel.springboot.routes-include-pattern. Beans in the Spring application context are available in Camel routes via .bean(BeanClass.class) or by Spring name. Health checks and JMX management are auto-configured when the relevant starters are on the classpath.
