In this article, we are going to see how you can map the
java.time.Month with both JPA and Hibernate.
As explained in this article, JPA 2.2 supports
OffsetDateTime from the
java.time package. Hibernate has been supporting the Java 8 Date/Time classes since 5.0 via the
hibernate-java8 dependency, but since version 5.2, this dependency was merged with
hibernate-core so you get the
ZonedDateTime types in addition to the ones supported by JPA 2.2.
However, neither JPA nor Hibernate supports the
java.time.Year type out-of-the-box. As you will see, adding support for
java.time.Year is very easy with both standard JPA or Hibernate.

In this article, we are going to see how you can map a
java.time.YearMonth with both JPA and Hibernate.
As I explained in this article, JPA 2.2 supports the following Date/Time types introduced in Java 8:
Apart from supporting those, Hibernate supports also:

Inspired by this StackOverflow answer I gave recently, I decided it’s time to write an article about query pagination when using JPA and Hibernate.
In this article, you are going to see how to use query pagination to restrict the JDBC
ResultSet size and avoid fetching more data than necessary.

In this article, I’m going to explain how the Spring read-only transaction Hibernate optimization works.
After taking a look at what the Spring framework does when enabling the
readOnly attribute on the
@Transactional annotation, I realized that only the Hibernate flush mode is set to
FlushType.MANUAL without propagating the read-only flag further to the Hibernate
So, in the true spirit of open-source software developer, I decided it’s time to make a change.

In this article, I’m going to summarise the most common Hibernate performance tuning tips that can help you speed up your data access layer.
While getting started with JPA and Hibernate is fairly easy, if you want to get the most out of your data access layer, it’s very important to understand how the JPA provider works, as well as the configuration properties that can help you optimize application performance.
