How to map Java Enum to custom values with JPA and Hibernate
Last modified:
Are you struggling with performance issues in your Spring, Jakarta EE, or Java EE application?
Imagine having a tool that could automatically detect performance issues in your JPA and Hibernate data access layer long before pushing a problematic change into production!
With the widespread adoption of AI agents generating code in a heartbeat, having such a tool that can watch your back and prevent performance issues during development, long before they affect production systems, can save your company a lot of money and make you a hero!
Hypersistence Optimizer is that tool, and it works with Spring Boot, Spring Framework, Jakarta EE, Java EE, Quarkus, Micronaut, or Play Framework.
So, rather than allowing performance issues to annoy your customers, you are better off preventing those issues using Hypersistence Optimizer and enjoying spending your time on the things that you love!
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.

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:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean entityManagerFactoryBean =
new LocalContainerEntityManagerFactoryBean();
entityManagerFactoryBean.setDataSource(dataSource());
⠀
...
⠀
entityManagerFactoryBean.setJpaVendorAdapter(
new HibernateJpaVendorAdapter()
);
entityManagerFactoryBean.setJpaProperties(additionalProperties());
return entityManagerFactoryBean;
}
protected Properties additionalProperties() {
Properties properties = new Properties();
properties.setProperty(
AvailableSettings.JAVA_TIME_USE_DIRECT_JDBC,
Boolean.TRUE.toString()
);
return properties;
}
Or you can set it declaratively in the Spring Boot application.properties configuration file like this:
spring.jpa.properties.hibernate.type.java_time_use_direct_jdbc=true
