📊[POLL] What is your preferred JSON LIBRARY in JAVA?
Jackson, Gson… or will Java 28 change your default choice?
JSON is everywhere in Java backend development: REST APIs, configuration, messaging, persistence, testing…
So what do you reach for first?
Poll options:
▪️ Jackson 🔥: my default
The heavyweight champion. Powerful data binding, annotations, custom serializers/deserializers and deep integration with frameworks like Spring Boot.
▪️ Gson 🧩: simple & light
Google's popular library. Easy to learn, lightweight and often enough when you just need straightforward Java ↔ JSON conversion.
▪️ JSON-B / JSON-P ☕
The Jakarta standards route. JSON-B focuses on binding Java objects, while JSON-P provides lower-level JSON processing.
▪️ It depends 🤷
Because the "best" JSON library depends on the job: framework integration, performance, object mapping, streaming, dependency footprint or API complexity.
And now there's a new player coming directly from Java. 👀
☕ JAVA 28 could change the equation
JEP 540: Simple JSON API (Incubator) is targeted for JDK 28.
It introduces jdk.incubator.json, giving Java a small built-in API for parsing, navigating and generating RFC 8259 JSON without adding an external dependency.
But it is deliberately not a mini replacement for everything Jackson or Gson can do.
No full object data binding.
No advanced streaming API.
No permissive JSON extensions.
The goal is simpler: cover common JSON tasks directly in the JDK and leave richer use cases to established libraries.
As Joshua Bloch said:
“When in doubt, leave it out.”
That philosophy fits JEP 540 surprisingly well.
So… if Java ships a good native JSON API, will it change your default choice?
