Generates Java types from JSON or JSON Schema and annotates them for data-binding with Jackson, Gson, etc.
jsonschema2pojo is a Java library that generates Plain Old Java Objects (POJOs) from JSON Schema or example JSON documents. It automates the creation of type-safe Java classes and annotates them for use with data-binding libraries like Jackson and Gson, simplifying JSON data handling in Java applications.
Java developers working with JSON APIs, microservices, or data serialization who need to create Java classes from JSON schemas or examples efficiently.
It eliminates manual POJO creation, ensures consistency with JSON schemas, and provides built-in support for major data-binding libraries, reducing boilerplate and potential errors.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Annotates generated types for seamless integration with Jackson 2.x, Jackson 3.x, or Gson, as highlighted in the README, ensuring broad data-binding support.
Offers Maven and Gradle plugins, command-line tool, and embeddable library options, making it easy to integrate into various development workflows without lock-in.
Generates POJOs automatically from JSON Schema or examples, reducing manual boilerplate coding and minimizing errors in type-safe class creation.
Provides configurable options for package names, source directories, and annotation styles, allowing tailored code generation to fit project needs.
Regenerating POJOs on schema changes can overwrite manual customizations, leading to merge conflicts and increased maintenance effort for complex projects.
The numerous options for annotations and mappings require careful setup, which can be daunting for beginners or when dealing with intricate JSON schemas.
Only generates Java classes, so it's not suitable for polyglot projects or teams using alternative JVM languages that might prefer native solutions.
