Hi Federico,
Apologies for my delayed response.
*Here is an example of the route where I am encountering the problem:*
@Component
public class MyRoute {
public MyRoute() {
setInput(direct(routeId()));
setOutput(direct(OUTPUT_ROUTE_ID));
}
@Override
public void configure() throws Exception {
super.configure();
from(getInput())
.routeId(routeId())
.unmarshal().json(MyPojo.class)
// processing data
.to(getOutput())
.end();
}
}
*Executable version: * @Component
public class MyRoute {
private final ObjectMapper objectMapper;
public MyRoute(ObjectMapper objectMapper) {
this.objectMapper = objectMapper;
setInput(direct(routeId()));
setOutput(direct(OUTPUT_ROUTE_ID));
}
@Override
public void configure() throws Exception {
super.configure();
JacksonDataFormat jacksonDataFormat = new
JacksonDataFormat(MyPojo.class);
jacksonDataFormat.setObjectMapper(objectMapper);
from(getInput())
.routeId(routeId())
.unmarshal(jacksonDataFormat)
// processing data
.to(getOutput())
.end();
}
}
By the way, I am currently using Spring Boot 2.5.0.
