Thanks for the patch. I ammended it a bit and built an unit test.
> JacksonDataFormat does not pickup custom ObjectMapper from Registry
> -------------------------------------------------------------------
>
> Key: CAMEL-11970
> URL: https://issues.apache.org/jira/browse/CAMEL-11970
> Project: Camel
> Issue Type: Improvement
> Components: camel-jackson
> Affects Versions: 2.19.2, 2.19.3, 2.20.0
> Reporter: Tim Lark
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 2.21.0
>
>
> When a custom ObjectMapper is properly configured as a Spring bean and exists in the Registry, it is ignored when the {{JacksonDataFormat.doStart}} method is invoked.
> The beginning of this method does a null check on {{objectMapper}} and simply creates one via {{new ObjectMapper()}} if null.
> I've prototyped a more robust solution below, which does pickup our custom ObjectMapper bean:
> +Before:+
> {code:java}
> @Override
> protected void doStart() throws Exception {
> if (objectMapper == null) {
> objectMapper = new ObjectMapper();
> }
> ...
> {code}
> +After:+
> {code:java}
> @Override
> protected void doStart() throws Exception {
> if (objectMapper == null) {
> CamelContext context = getCamelContext();
> if (context == null) {
> LOG.error("doStart: No camelContext defined");
> }
> else {
> Map<String, ObjectMapper> mappersByName = context
> .getRegistry()
> .findByTypeWithName(ObjectMapper.class);
> LOG.debug("doStart: Found objectMappers={}", mappersByName);
> if (mappersByName.size() >= 1) {
> Map.Entry<String, ObjectMapper> mapperByName = mappersByName
> .entrySet()
> .iterator()
> .next();
> objectMapper = mapperByName.getValue();
> LOG.debug("doStart: Using objectMapper=[name:{}, {}]", mapperByName.getKey(), objectMapper);
> }
> }
> if (objectMapper == null) {
> objectMapper = new ObjectMapper();
> LOG.warn("doStart: Using new default objectMapper={}", objectMapper);
> }
> }
> ...
> {code}
> An enhancement to this would be to allow the *bean name* to be specified instead of simply choosing the first one found.
