How do I override Atlassian's instantiation of ObjectMapper?

[David Maye]

We are developing an Atlassian Confluence plugin (starting with RefApp, because it is a lighter app to develop on) using the Atlassian REST API plugin module (atlas-create-refapp-plugin-module, option 7 or atlas-create-confluence-plugin-module, option 9). (The front-end is Angular, so we are relying on the Rest API for the whole app.)

I need to customize the Jackson ObjectMapper. Here are two related Atlassian Community posts that are unanswered/only partially answered:

https://community.developer.atlassian.com/t/can-i-customize-the-jackson-objectmapper/31069

https://community.atlassian.com/t5/Jira-Core-questions/How-to-customize-Jackson-ObjectMapper/qaq-p/242012

Here is what I want access to:

Jackson Serialization Features:
https://github.com/FasterXML/jackson-databind/wiki/Serialization-Features

Jackson Deserialization Features:
https://github.com/FasterXML/jackson-databind/wiki/Deserialization-Features

I have dug through the code of Atlassian's REST API module:

https://bitbucket.org/atlassian/atlassian-rest/src/master/atlassian-rest-module/src/main/java/com/atlassian/plugins/rest/module/

How do I override Atlassian's instantiation of ObjectMapper and register it with the appropriate modules so that I can use my own Jackson ObjectMapper settings?

Just add Jackson as dependency and use it directly.

(Please note: don't let Bandana serialize your objects, use your own mapper then. Avoids many problems…)

pom.xml

<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <!-- Jackson 2.15.0 may break with older Java -> test again, when with > 2.15.0 -->
   <version>2.14.2</version>
</dependency>

Code

ObjectMapper objectMapper = new ObjectMapper();

@David Maye did you ever figure out how to do this?

It is just amazing how all the nitty-gritty questions are left unanswered.

I just consume the raw JSON string in my method and call my own object mapper.
