From 1d1e033fc0ad3c979f65c87d80f6e1dd695a5baa Mon Sep 17 00:00:00 2001 From: Sven Walter Date: Wed, 23 May 2018 09:21:07 +0200 Subject: [PATCH] Use MessageBuilder to also copy readOnly headers (#17) Reasoning: The current approach removes the "timestamp" and "id" header, because the copyHeaders will not copy readOnly headers. Using the MessageBuilder will ensure that all headers from the original message, including id/timestamp will also be in the result message. --- .../integration/messaging/MessageTextMap.java | 31 +++++++------------ .../messaging/MessageTextMapTest.java | 18 ++++++++++- .../OpenTracingChannelInterceptorIT.java | 1 + 3 files changed, 29 insertions(+), 21 deletions(-) diff --git a/opentracing-spring-messaging/src/main/java/io/opentracing/contrib/spring/integration/messaging/MessageTextMap.java b/opentracing-spring-messaging/src/main/java/io/opentracing/contrib/spring/integration/messaging/MessageTextMap.java index 59c32ac..a14cd0e 100644 --- a/opentracing-spring-messaging/src/main/java/io/opentracing/contrib/spring/integration/messaging/MessageTextMap.java +++ b/opentracing-spring-messaging/src/main/java/io/opentracing/contrib/spring/integration/messaging/MessageTextMap.java @@ -1,5 +1,5 @@ /** - * Copyright 2017 The OpenTracing Authors + * Copyright 2017-2018 The OpenTracing Authors * * Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except * in compliance with the License.
