How to integrate Jakarta Data with Spring and Hibernate
Introduction In this article, we are going to see how we can integrate Jakarta Data with Spring and Hibernate. Jakarta Data is a new Jakarta EE specification that provides a common API for building data Repositories and data access objects. If you are familiar with Spring Data JPA, you will see that Jakarta Data is very much inspired by this Spring API.
Hibernate SoftDelete annotation
Introduction In this article, we are going to see how we can use the Hibernate SoftDelete annotation to activate soft deleting for JPA entities. While, as I explained in this article, you can manually implement the soft delete mechanism using the @SQLDelete, @Loader and @Where annotations, it’s definitely much easier to just use the native Hibernate mechanism introduced in Hibernate 6.4 , which you can enable via the @SoftDelete annotation.
How to map Java Enum to custom values with JPA and Hibernate
Introduction In this article, we are going to see how we can map Java Enum to custom values when using JPA and Hibernate. While Hibernate provides several options to save Enum values, having the option to customize this mechanism is even better, as it will allow you to better deal with legacy applications or use cases that require you to reorder the Java Enum values.
How does the Hibernate JAVA_TIME_USE_DIRECT_JDBC setting work
Introduction In this article, we are going to see how the Hibernate JAVA_TIME_USE_DIRECT_JDBC setting works and what JDBC Driver supports this feature. This setting can be set programmatically, as illustrated by the following Spring Java-based configuration: Or you can set it declaratively in the Spring Boot application.properties configuration file like this:
Hibernate WITH RECURSIVE query
Introduction In this article, we are going to see how the Hibernate WITH RECURSIVE query works and how we can use it to fetch hierarchical data structures.
Hibernate ON CONFLICT DO clause
Introduction In this article, we are going to see how the Hibernate ON CONFLICT DO clause works, and how we can use it to execute an SQL UPSERT statement in a portable way.
Overriding FetchType.EAGER with fetchgraph
Introduction In this article, we are going to see how you can override the FetchType.EAGER strategy using the fetchgraph query hint. While this feature has been available in the JPA specification since version 2.1, Hibernate has only supported this feature since version 5.5.
