Apache CXF - Set HTTP header

Question

I have to set some http header fields in a Apache CXF client:

I tried it via Interceptor:

    public class HttpHeaderInterceptor extends AbstractPhas         


        

Answer 1

Here is a code snippet to copy a custom HTTP header (from the request) on the response in a single CXF out interceptor.

public void handleMessage(SoapMessage message) throws Fault {
    // Get request HTTP headers
    Map> inHeaders = (Map>) message.getExchange().getInMessage().get(Message.PROTOCOL_HEADERS);
    // Get response HTTP headers
    Map> outHeaders = (Map>) message.get(Message.PROTOCOL_HEADERS);
    if (outHeaders == null) {
        outHeaders = new HashMap<>();
        message.put(Message.PROTOCOL_HEADERS, outHeaders);
    }
    // Copy Custom HTTP header on the response
    outHeaders.put("myCustomHTTPHeader", inHeaders.get("myCustomHTTPHeader"));
}
