Action Jackson! Effective JSON processing in Spring Boot Applications by Joris Kuipers @ Spring I/O

Spring I/O 2023 - Barcelona, 18-19 May

JSON processing plays an important role in nearly all applications nowadays, and Jackson is the de-facto standard library for that. Most developers are therefore familiar with using it for simple (un)marshalling purposes, but never go beyond the basics. In this session Joris will show how to effectively configure and use Jackson, focusing on Spring Boot applications. Boot provides a lot of support for configuring ObjectMappers, which you can use directly but are also used internally by the framework for e.g. handling HTTP requests/responses or message conversion. Topics will include tuning mappings, using modules, applying views and using alternative parsing options like JSON Pointer and JsonPath, all illustrated through live demos. Don’t miss out on this presentation and become an Action Jackson yourself!

Everyone uses json, but few videos about it. Thank you so much.

Very good talk where whe can see the interesting options we have to customaize the JSON serialization and deserialization

Excellent talk!! I really enjoyed it. Thank you Joris!

[ivandenysenko]

Great talk. Thanks for sharing your experience.

[kevinnguyen]

Excellent! Thank you for such a great talk.

This is a very good talk for me, who's getting introduced to java and spring boot

I can think on one reason to create an ObjectMapper instance without the builder: a client library (Do not want user configuration mess up your requests)

Great talk (e.g. I didn't know about Views - seems sort of custom graphql can be implemented using it :).
@Joris, I have a question - is it possible to configure properly serialization/deserialization with lombok delegate feature ( lombok.experimental.Delegate) - or fields should always be present on the target class?

Does the new library passes all CVE vulnerabilities?

[rydmerlin]

As you demonstrated the parameters example I was thinking what happens when folks use any kind of code obfuscation.

[rydmerlin]

Even if you create an objectmapper in the controller. How do you ensure endpoints in that controller will use it?
