BeanCreationException: Component declared but not exist in registry - spring

Question

I started learning camel recently and trying out some sample application. I have encountered this error while loading application context as part of testcase run,
... 45 more Caused by: org.apache.camel.FailedToCreateRouteException:

Tried my best by googling and looking at stack overflow to resolve but my effort went in vain. Need some help.
Here is my folder structure
Below are some related files used w.r.t to my sample application for your reference,
Application.java:
---------------------
#Configuration
#ComponentScan(basePackages = "com.pluralsight.orderfulfillment")
#PropertySource("classpath:order-fulfillment.properties")
public class Application {
}
IntegrationConfig.java:
-------------------------
#Configuration
public class IntegrationConfig extends CamelConfiguration {
#Inject
private Environment environment;
#Inject
private DataSource datasource;
#Bean
public SqlComponent sql() {
SqlComponent sqlComponent = new SqlComponent();
sqlComponent.setDataSource(datasource);
return sqlComponent;
}
#Bean
public RouteBuilder newWebsiteOrderRoute() {
return new RouteBuilder() {
#Override
public void configure() throws Exception {
from("sql:"
+ "select id from orders.\"order\" where status = '"
+ OrderStatus.NEW.getCode()
+ "'"
+ "?"
+ "consumer.onConsume=update orders.\"order\" set status = '"
+ OrderStatus.PROCESSING.getCode()
+ "' where id=:#id")
.beanRef("orderItemMessageTranslator", "transformOrderItemMessage")
.to("log:com.pluralsight.orderfulfillment.order?level=INFO");
}
};
}
}

Thanks in advance for help.

Answer 1

Have you decorated the OrderItemMessageTranslator with the #Component annotation?
Instead of .beanRef(..), try the .bean(..) builder method from the Java DSL(http://camel.apache.org/bean.html#Bean-JavaDSLbeansyntax):
.bean(new OrderItemMessageTranslator(), "transformOrderItemMessage")
UPDATE:
If you would like to use the .beanRef(..) method then try to add #ComponentScan(..) to the IntegrationConfig which extends CamelConfiguration.
Like this: http://camel.apache.org/spring-java-config.html#SpringJavaConfig-Configuration
