Introduction In this article, we are going to see how easy it is to map an SQL Server JSON column when using the Hibernate Types project. Not only that the hibernate-types project supports JSON column types for PostgreSQL and MySQL and Oracle, but, as you will see in this article, the JsonStringType works just fine when using Microsoft SQL Server.
Introduction In this article, we are going to see how to map the Oracle JSON column storage types when using JPA and Hibernate. My hibernate-types project has long been supporting JSON for PostgreSQL and MySQL. However, while developing my new and awesome SQL Master Class training, I realized that the current implementation does not handle Oracle JSON column types properly. Luckily, the fix was easy and starting with the 2.7.0 version you can now persist and fetch JSON attributes on Oracle using JPA and Hibernate.
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 into 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.
