Trying to call camel/javaee from springboot

Question

I'm trying to call camel/java-ee/class (it's very long programs, so no time to convert) from a spring-boot. So for now the solution is to just start with spring-boot and call the main class.

Here's the main application of springboot that will call the javaee/class, I tried the simple bean calling before, so this my latest test for I thought its about the proper call of bean, but unfortunately, even the proper calling of bean have the same error as the simple calling of bean,

@SpringBootApplication
public class App {
    public static void main(String[] args) throws Exception {
        ApplicationContext applicationContext = SpringApplication.run(App.class, args);
        BeanAppService service = applicationContext.getBean(BeanAppService.class);
        service.callInitCamelJavaEE();
    }
}

Service interface,

public interface BeanAppService {
    
    void callInitCamelJavaEE() throws Exception;

}

Configuration,

@Configuration
public class BeanAppConfig {

    @Bean
    public BeanAppService beanAppConfig() {
        return new BeanApp();
    }

}

BeanApp (this is the original main class with args in java/ee),

public class BeanApp implements BeanAppService {
    public BeanApp() {}
    
    protected <I extends SpongeRequest, O extends SpongeResponse> void createOperation(RestDefinition restDefinition, String operation,
    String operationDescription, Class<I> requestClass, String requestDescription, Class<O> responseClass,
    String responseDescription, BiFunction<I, Exchange, O> operationHandler) {
  restDefinition.post(operation).description(operationDescription).type(requestClass).outType(responseClass).param().name("body")
      .type(body).description(requestDescription).endParam().responseMessage().code(200).message(responseDescription)
      .endResponseMessage().route().id("sponge-" + operation).process(exchange -> {
        String requestBody = exchange.getIn().getBody(String.class);
        if (logger.isDebugEnabled()) {
          logger.debug("REST API {} request: {}", operation, RestApiUtils.obfuscatePassword(requestBody));
        }
        try {
          setupResponse(operation, exchange,
              operationHandler.apply(getObjectMapper().readValue(requestBody, requestClass), exchange));
        } catch (Throwable processingException) {
          logger.info("REST API error", processingException);
          try {
            setupResponse(operation, exchange, apiService.createGenericErrorResponse(processingException, exchange));
          } catch (Throwable e) {
            logger.error("REST API send error response failure", e);
            throw e;
          }
        }
      }).endRest();
    }

    @Override
    public void callInitCamelJavaEE() throws Exception {
        try (CamelContext camelContext = new DefaultCamelContext()) {
            camelContext.addRoutes(new RouteBuilder() {
                @Override
                public void configure() throws Exception {
                    restConfiguration().enableCORS(true).setPort("8080");
                }
            });
            camelContext.start();
            Thread.sleep(6000000);
            camelContext.stop();
        }   
        
    }

The error,

Anyone who have encountered this before?

Seems like in the route builder you have not configured any route.

@Override
public void callInitCamelJavaEE() throws Exception {
    try (CamelContext camelContext = new DefaultCamelContext()) {
        camelContext.addRoutes(new RouteBuilder() {
            @Override
            public void configure() throws Exception {
                restConfiguration().enableCORS(true).setPort("8080");
            }
        });
        camelContext.start();
        Thread.sleep(6000000);
        camelContext.stop();
    }   
    
}
