Imagine having a tool that can automatically detect if you are using JPA and Hibernate properly.
Hypersistence Optimizer is that tool!
In this article, I want to show you how you can map a String JPA property to a JSON database column using the hibernate-types open-source project.
Although it’s probably more common to use a JsonNode or POJO (Plain Old Java Object) on the Java side, the hibernate-types framework is very flexible and allows you to use a String JPA property type to represent a JSON structure.
Based on my book, High-Performance Java Persistence, this workshop teaches you various data access performance optimizations from JDBC, to JPA, Hibernate and jOOQ for the major rational database systems (e.g. Oracle, SQL Server, MySQL and PostgreSQL).
The SQL Master Class for Java Developers training is aimed to level up your SQL skills with techniques such as Window Functions, recursive queries, Pivoting, JSON processing, and many other database querying features supported by Oracle, SQL Server, MySQL, or PostgreSQL.
