Description

I am trying to create a Camel REST service via Java DSL that can consume/produce both json and xml and the JSON works but I receive the an error when I try to retrieve the result in XML.

RestConfiguration:

/**
 * This configuration is for start the Apache Camel application with the Spring Boot servlet
 * @author rafael.manzoni
 */
public class RestConfiguration extends RouteBuilder {

 @Override
 public void configure() throws Exception {
 restConfiguration()
 .component("servlet")
 .contextPath("/credits/v1")
 .enableCORS(true)
 .apiContextPath("/api-doc")
 .apiProperty("api.title", "REST API")
 .apiProperty("api.version", "v1")
 .apiContextRouteId("doc-api")
 .bindingMode(RestBindingMode.auto)

 .dataFormatProperty("prettyPrint", "true")
 .dataFormatProperty("mustBeJAXBElement", "true");
 }


}

RestMethods:

/**
 * Rest methods configuration. Apply all HTTP routes to Camel Routes
 * @author REST Methods Configuration
 */
public class RestMethods extends RouteBuilder {

 @Override
 public void configure() throws Exception {
 rest()
 .bindingMode(RestBindingMode.auto)
 .consumes("application/json, application/xml")
 .produces("application/json, application/xml")
 .get("/rating")
 .toD("direct:getRatingByClient");
 }

}

 

Route Implementation:

public class GetRatingByClientRoute extends RouteBuilder{

 // Use to created the mock
 private final ObjectMapper objectMapper = new ObjectMapper();

 @Override
 public void configure() throws Exception {
 
 from("direct:getRatingByClient")

 // Request
 .to("log:init")

 // Mediation
 .process(exchange -> {

 // TODO Implement route
 TestEntity test = new TestEntity();
 test.setTestAttribute("Teste");
 exchange.getIn().setBody(test);
 })

 // Response
 .to("log:end");
 
 }

}

When I run with Content-Type application/json works like a charm. But, when i run with Content-Type application/xml i got this error: java.io.IOException: org.apache.camel.InvalidPayloadException: No body available of type: javax.xml.bind.JAXBElement but has value: class GetRatingByClientRouteResponse

Follow the requisition that I´m testing:

Success:

curl -X GET \ 'http://localhost:8080/credits/v1/rating?client_cpf_cnpj=11111111111' \ -H 'Accept: application/json' \ -H 'Cache-Control: no-cache' \ -H 'Content-Type: application/json'

 

Failure:

curl -X GET \ 'http://localhost:8080/credits/v1/rating?client_cpf_cnpj=11111111111' \ -H 'Accept: application/xml' \ -H 'Cache-Control: no-cache' \ -H 'Content-Type: application/xml'

 

I´m attaching the project to this issue.
