How to Preserve Table Name Casing in Spring Boot JPA with Hibernate?

Preserving Table Name Casing in Spring Boot JPA with Hibernate

When working with Spring Boot JPA and Hibernate, it's essential to ensure that table names are correctly interpreted and preserved in database operations. By default, Hibernate converts table names to lowercase based on its naming conventions. However, this may not correspond to the actual table name in the database, leading to challenges in inserting new records.

Overcoming Table Name Lowercase Conversion

To avoid the table name conversion issue without modifying MySQL configuration, you can leverage the following solution:

For Hibernate 5 and above, add the following property to your application.properties file:

spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

By setting this property, you instruct Hibernate to use the PhysicalNamingStrategyStandardImpl, which preserves the original table name casing. It prevents Hibernate from altering the table name during database operations.

Ensuring Successful Record Insertion

Once you implement this solution, Hibernate will maintain the table name casing as specified in your database schema. This allows you to successfully insert new records without encountering issues arising from table name discrepancies.
