Introduction

The Hibernate Types repository gives you extra types and general purpose utilities that are not supported by the Hibernate ORM core.

The main advantage of this project is that it supports a broad range of Hibernate versions, spanning from Hibernate 4.1 to Hibernate 5.4.

Features

JSON

• Jackson JsonNode
• Java Object to String or Binary JSON column mapping
• Java Collection to String or Binary JSON column mapping
• How to customize the Jackson ObjectMapper used by Hibernate-Types
• How to customize the JSON Serializer used by Hibernate-Types
• How to fix the Hibernate “No Dialect mapping for JDBC type: 1111” issue when mixing JSON types with native SQL queries

PostgreSQL Types (e.g. ARRAY, ENUM, INET)

• PostgreSQL ARRAY mapping
• Java Enum to PostgreSQL Enum Type
• How to map the PostgreSQL inet type with JPA and Hibernate

Generic Types

• java.time.YearMonth to DATE or INTEGER column
