org.apache.camel.FailedToStartRouteException: Failed to start route route1 because of null

I am new to apache camel. I am trying to consume json, convert it into java object and write it in CSV file with pipe delimiter. However I am getting error while trying to consume the json from another api's endpoint. I am using spring boot to achieve this task.

Attached the sample code which I am trying.

@Component
public class HRFeedRoute extends RouteBuilder {

	@Override
    public final void configure() {
    	System.out.println("fetching employee details from employee api");
    	try {
    		from("http://localhost:8083/getEmployee").startupOrder(1).to("direct:employee")
    		.log("${body}");
    				
    		from("direct:employee")
            .unmarshal().json(JsonLibrary.Jackson, Employee.class)
            .process(
					ex -> {
	                    System.out.println(ex);
	                });
            
    	} catch(Error e) {
    		System.out.println("Error occurred while processing employee data: "+e.getMessage());
    	}
    }
}

Caused by: java.lang.UnsupportedOperationException: Cannot consume from http endpoint

The last line of the error message is the key:

Caused by: java.lang.UnsupportedOperationException: Cannot consume from http endpoint

camel-http and camel-http4 (for Camel 2.x) are only usable as producer, but not as consumer.

You need to use for example camel-jetty that can consume http requests.

I found the answer.
Jetty will expose an end point URL which will be used by the producer to send the json/message. So add the end poin url exposed by jetty in the producer.
Add camel-jetty-starter dependency in the pom.xml
Producer:
Assuming that you are aware of how the rest api will post the message to another api. Hence, I am just sharing the postEntity code from the controller.

ResponseEntity responseEntity = restTemplate.postForEntity(new URI("http://localhost:8084/employee-package/getEmployee"), request, Employee.class);

Consumer API Router:

@Component
public class HRFeedRoute extends RouteBuilder {

@Override
public final void configure() {
System.out.println("fetching employee details from employee api");
try {
from("jetty://http://localhost:8084/employee-package/getEmployee")
.log("${body}")
.unmarshal().json(JsonLibrary.Jackson, Employee.class)
.process(
ex -> {
Employee employee = (Employee) ex.getIn().getBody();
System.out.println("|"+employee.getEmpId()+" | "+employee.getName()+" | "+employee.getDesignation()+" | "+employee.getSalary());
});
} catch(Error e) {
System.out.println("Error occurred while processing employee data: "+e.getMessage());
}
}

}
