@Provider
@PreMatching
public class LoggingFilter implements ContainerRequestFilter, ContainerResponseFilter
{
    final Logger logger = Logger.getLogger(LoggingFilter.class);

    @Override
        public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
        {
            logger.info("------------------------------------------------------------");
            logger.info("Container-Response");
            logger.info("Status: " + responseContext.getStatus());

            for (Map.Entry<String, List<Object>> entry : responseContext.getHeaders().entrySet())
            {
                logger.info(entry.getKey() + ":" + entry.getValue().toString());
            }

            BufferedReader br;
            try
            {
                br = new BufferedReader(new InputStreamReader((InputStream) responseContext.getEntity(), "UTF-8"));

                        StringBuilder xml = new StringBuilder();
                String line;

                while ((line = br.readLine()) != null)
                {
                    xml.append(line);
                }

                logger.info(xml);
                responseContext.setEntity(new ByteArrayInputStream(xml.toString().getBytes("UTF-8")));
            } catch (IOException e)
            {

                e.printStackTrace();

            }

        }

 }
