Trying to call camel/javaee from springboot - spring-boot

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,
StreamCaching is not in use. If using streams then it's recommended to enable stream caching. See more details at http://camel.apache.org/stream-caching.html

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();
}
}
Assuming you are using Rest here is How to configure a route in RouteBuilder using REST DSL
