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 ~
