Submit Camel rest-dsl 400 Status Codes

Question

I develop REST services using the REST-DSL camel [in the camel documentation] . I successfully sent a JSON request for a happy journey and get an answer to the same combination (Rest-DSL and camel servlet). Now that we are moving forward, the client can send a Restore service request with invalid values ​​or an invalid valid request, now I am looking for ways to send the 400 status code as a response from the REST DSL when the request is invalid.

Please provide information on how to do this.
