Class Jackson3JsonFormatMapper

java.lang.Object

org.hibernate.type.format.AbstractJsonFormatMapper

org.tailormap.api.configuration.Jackson3JsonFormatMapper

All Implemented Interfaces:

org.hibernate.type.format.FormatMapper

public class Jackson3JsonFormatMapper
extends org.hibernate.type.format.AbstractJsonFormatMapper

Custom JSON format mapper for Hibernate that uses the Jackson 3 library for JSON serialization and deserialization. This format mapper allows Hibernate to handle JSON types using Jackson, which is the primary JSON processing library used in the application. By implementing this custom format mapper, we ensure that Hibernate can correctly serialize and deserialize JSON properties in a way that is compatible with the application's JSON processing needs, especially since Hibernate 7.2.x does not natively support Jackson 3. See HibernateConfiguration for how this format mapper is registered with Hibernate and:

• Spring Boot issue #47789
• Demo project illustrating the issue with JSON serialization in Spring Boot 4 and Hibernate 7.2.x
• Hibernate issue HHH-19890 regarding JSON format mappers and Jackson 3 support
• Pull request in Hibernate ORM to add support for Jackson 3 in JSON format mappers

for more context on the need for a custom JSON format mapper with Hibernate 7.2.x and Jackson 3. This class should be removed after Hibernate 7.3.x or higher is released/implemented in TM.
