json

A small, hardened JSON library for Java 25. Annotate a record, class, or sealed interface with @JSON and a compile-time annotation processor generates the serializer and deserializer for it — no reflection, and nothing from this library on your runtime path.

Install

Add the processor to your project.latte:

dependencies {
  group(name: "compile-processors") {
    dependency(id: "org.lattejava:json:0.2.0")
  }
}

Example

@JSON
public record User(String name, int age, String email) {}

import com.example.internal.UserJSON;

String json = UserJSON.toJSON(user);     // serialize
User   back = UserJSON.fromJSON(json);   // deserialize

Features

• Compile-time codegen — zero reflection; the companion is plain generated Java
• No runtime dependency — org.lattejava:json never lands on your compile classpath or runtime path
• Records, classes, and JavaBeans — plus discriminated sealed hierarchies
• Flexible mapping — naming strategies, per-field renames, catch-all members, and date/time control
