Introduction The open-source hibernate-types project allows you to map Java objects or Jackson JsonNode as JPA or Hibernate entity properties, and, thanks to our awesome contributors, we have added support for storing type-safe JSON collections. In this article, you are going to see how to achieve this goal.
Introduction Recently, I got a very interesting request from one of my readers. Since I’ve been providing many custom types to support JSON, ARRAY or nullable Character types, I decided to start a new open-source project to make it easier for you to get this extra Hibernate Types.
Introduction One of my Twitter followers has recently asked me about a way of storing EAV (Entity-Attribute-Value) data using JPA and Hibernate, and, because this is a very good question, I decided to turn answer it using a blog post. In this article, you are going to see how you can use JSON types to store schema-less EAV data.
Introduction Since not all relational database systems support JSON types, Hibernate does not come with a built-in JSON Type mapper. Traditionally, all custom types have been supplied via a UserType implementation. However, a UserType is not very developer friendly so, in this post, I’m going to show how you can do a better job using AbstractSingleColumnStandardBasicType instead.
