   Surprisingly ! 
    I meet the same problem......In dubbo's rest protocal, before the RpcContextFilter of implements ContainerRequestFilter  sets header's k/v into  RpcContext's Attachment, require value must be contain '=' or ',' .
   
   For this situation, I can't give up dubbo' rest protocal or SW. 
   
   So, make something to figure it out.
   
   Here is a complete and perfect solution !
   
   First:
   ---------------------part one---------------------------
   @Provider
   @Priority(Priorities.HEADER_DECORATOR )
   public class SwClientFilter implements ClientRequestFilter {
   
       @Override
       public void filter(ClientRequestContext requestContext) throws IOException {
           for (Map.Entry<String, String> entry : RpcContext.getContext().getAttachments().entrySet()) {
               if (entry.getKey().equals("sw6")){
                   String value = entry.getValue();
                   String replaceAll= value.replaceAll("=", "%");
                   entry.setValue(replaceAll);
                   return;
               }
           }
       }
   }
   
   -----------------------------part two.--------------------------
   @Provider
   @Priority(Integer.MIN_VALUE + 20)
   public class SwContainerFilter implements ContainerRequestFilter {
   
       @Override
       public void filter(ContainerRequestContext requestContext) {
           for (Map.Entry<String, String> entry : RpcContext.getContext().getAttachments().entrySet()) {
               if (entry.getKey().equals("sw6")){
                   String value = entry.getValue();
                   String replaceAll= value.replaceAll("%", "=");
                   entry.setValue(replaceAll);
                   return;
               }
           }
       }
   }
   
   
   Then:
   
   add custom filter in <dubbo:protocal extension="........................">
   
   
   
   Welcom to try it ~
