Camel - Can't access rest service

Question

I'm running camel via spring and camel boot with embedded tomcat. I have a simple camel route that is configuring correctly and consuming that I can see in the logs, but when i try to access it, it is giving 404 with localhost:8080/hi.

My Route

 @Component
 public class ServiceRoute extends RouteBuilder {

 @Autowired
 private SampleBean sampleBean;

 @Override
 public void configure() throws Exception {
   from("rest:get:hi").to("bean:sampleBean");
 }
}

My Main class

@Configuration
@SpringBootApplication
@ComponentScan(basePackages = { "routes", "service" },
    excludeFilters = {@ComponentScan.Filter(value = Controller.class,     
    type = FilterType.ANNOTATION)})

public class Application  {

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}
}

Answer 1

It's not working, because the Camel HTTP Servlet is not registered. CamelAutoConfiguration just starts the camel context.

You need to register the servlet yourself. The default name of the camel servlet is CamelServlet. Change your Application class:

@SpringBootApplication
@ComponentScan(basePackages = { "routes", "service" },
    excludeFilters = {@ComponentScan.Filter(value = Controller.class,     
    type = FilterType.ANNOTATION)})

public class Application  {

    public static void main(String[] args) {
      SpringApplication.run(Application.class, args);
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new CamelHttpTransportServlet(), "/service/*");
        registration.setName("CamelServlet");
        return registration;
    }
}

And then try to access http://localhost/service/hi

Btw, you don't need to add @Configuration to the class annotated with @SpringBootApplication.
