## What it is
Hypersistence Utils (formerly Hibernate Types) is a Java library providing extra Hibernate custom types and Spring utilities for the data access layer. It supports a wide range of Hibernate ORM versions from 5.0 through 7.4.

## Use cases
- map JSON columns to Java entities in Hibernate
- persist arrays and enums as custom Hibernate types
- get extra Spring and Spring Data JPA utilities
- support many Hibernate versions with one library
- improve JPA data access layer performance

## When to choose
- you use Hibernate/JPA and need JSON, array, or enum column mappings
- you want Spring utilities alongside Hibernate custom types
- you need compatibility across many Hibernate versions

## When to avoid
- you don't use Hibernate or Spring in your project
- you need a full ORM rather than utilities
- you use a non-JVM language

## Facets
- artifact type: library
- maturity: active
- function: orm, serialization, developer-tools
- domain: databases, backend, developer-tools
- platform: jvm
- tags: hibernate, spring, jpa, custom-types, data-access
