Introduction In this article, I’m going to show you how you can set up connection monitoring for your JPA and Hibernate application, no matter if you are using Spring or other application frameworks.
Introduction In this article, I’m going to explain how the configure the Maven and Gradle Hibernate Enhance Plugin. The goal of the Hibernate Enhance plugin is to instrument the JPA entity bytecode in order to improve the effectiveness and efficiency of the associated data access operations.
Introduction In this article, I’m going to explain how the Hibernate LazyToOne annotation works and why you should use NO_PROXY lazy loading with bytecode enhancement. Without the LazyToOneOption.NO_PROXY annotation, the parent-side of a @OneToOne association is always going to be fetched eagerly even if you set it to FetchType.LAZY and enabled bytecode enhancement lazy loading.
Introduction In this article, I’m going to explain how we can map Java Records to JSON columns when using Hibernate. Because Hibernate ORM does not offer built-in support for JSON, we are going to use the Hiberate Types library, which allows you to map entity attributes to JSON column types, no matter if you are using Oracle, SQL Server, PostgreSQL, or MySQL.
Introduction In this article, I’m going to explain how the JPA and Hibernate first-level mechanism works and how it can improve the performance of your data access layer. In JPA terminology, the first-level cache is called Persistence Context, and it’s represented by the EntityManager interface. In Hibernate, the first-level cache is represented by the Session interface, which extends the JPA EntityManager one.
Introduction In this article, I’m going to explain how the Hibernate Session doWork and doReturningWork methods work, and when you should use them.
Introduction To ensure that your Spring Boot application fulfills the SLA (Service Level Agreement) requirements, you need a performance monitoring tool. In this article, I’m going to show you how you can monitor the data access layer of a Spring Boot application using Hypersistence Optimizer.
Introduction If you are wondering why and when you should use JPA or Hibernate, then this article is going to provide you an answer to this very common question. Because I’ve seen this question asked very often on the /r/java Reddit channel, I decided that it’s worth writing an in-depth answer about the strengths and weaknesses of JPA and Hibernate. Although JPA has been a standard since it was first released in 2006, it’s not the only way you can implement a data access layer using Java. We are going to discuss… Read More
Introduction In this article, we are going to see how the Hibernate hbm2ddl.auto schema generation tool works, and when it’s appropriate to use it.
