CXF RequestContextFilter

Question

http://cxf.apache.org/docs/30-migration-guide.html

CXF RequestHandler and ResponseHandler filters have been removed, please use JAX-RS 2.0 ContainerRequestFilter and ContainerResponseFilter and also WriterInterceptor and ReaderInterceptor when needed.

How to rewrite it? I cant find any examples taking org.apache.cxf.message.Message as a parameter and returning Response.

Also I should use the ContainerResponseFilter

public void filter(ContainerRequestContext containerRequestContext, ContainerResponseContext containerResponseContext) throws IOException {

instead of RequestHandler

Response handleRequest(Message m, ClassResourceInfo resourceClass)

Answer 1

Replace RequestHandler

public class CustomRequestHandler implements RequestHandler {
    public Response handleRequest(Message m, ClassResourceInfo resourceClass) {

with ContainerRequestFilter

public class CustomRequestFilter implements ContainerRequestFilter {
    public void filter(ContainerRequestContext context) {
        Message m = JAXRSUtils.getCurrentMessage(); 
        OperationResourceInfo m = message.getExchange().get(OperationResourceInfo.class);
        ClassResourceInfo resourceClass = operation.getClassResourceInfo();
        // finally use context.abortWith(Response) if you need to block the request 

Replace ResponseHandler

public class CustomResponseHandler implements ResponseHandler {
    public Response handleResponse(Message m, OperationResourceInfo operation, Response response) {

with ContainerResponseFilter

public class CustomResponseFilter implements ContainerResponseFilter  {
    public void filter(ContainerRequestContext inContext, ContainerResponseContext outContext) throws IOException{
        Message m = JAXRSUtils.getCurrentMessage();
        OperationResourceInfo operation = m.getExchange().get(OperationResourceInfo.class);
        //outContext has the capabilites of javax.ws.rs.Response. For example outContext.setStatus(201);
