I have a REST service built using Jersey.
I want to be able to set the MIME of my custom exception writers depending on the MIME that was sent to the server. application/json
is returned when json is received, and application/xml
when xml is received.
Now I hard code application/json
, but that's making the XML clients left in the dark.
public class MyCustomException extends WebApplicationException {
public MyCustomException(Status status, String message, String reason, int errorCode) {
super(Response.status(status).
entity(new ErrorResponseConverter(message, reason, errorCode)).
type("application/json").build());
}
}
What context can I tap into to get the current requests Content-Type
?
Thanks!
Update based on answer
For anyone else interested in the complete solution:
public class MyCustomException extends RuntimeException {
private String reason;
private Status status;
private int errorCode;
public MyCustomException(String message, String reason, Status status, int errorCode) {
super(message);
this.reason = reason;
this.status = status;
this.errorCode = errorCode;
}
//Getters and setters
}
Together with an ExceptionMapper
@Provider
public class MyCustomExceptionMapper implements ExceptionMapper<MyCustomException> {
@Context
private HttpHeaders headers;
public Response toResponse(MyCustomException e) {
return Response.status(e.getStatus()).
entity(new ErrorResponseConverter(e.getMessage(), e.getReason(), e.getErrorCode())).
type(headers.getMediaType()).
build();
}
}
Where ErrorResponseConverter is a custom JAXB POJO
