Store Arrays & Collections In JSON & XML In Hibernate
- Hibernate 6.x simplifies the mapping of Java collections and arrays directly to JSON and XML formats, increasing both flexibility and performance.
- To leverage Hibernate’s ability to store arrays and collections as JSON or XML types, one needs to include the required dependencies in the project. The dependencies are org.hibernate.orm:hibernate-core, com.fasterxml.jackson.core:jackson-databind and com.h2database:h2.
- Arrays (both primitive and non-primitive) can now be mapped to database columns with newer features that allow storing in JSON or XML format.
- Similarly, collections like lists or sets can also be stored as JSON/XML columns. This helps provide a structured way to store complex data while retaining the flexibility of non-relational data types.
- Migrating from Hibernate 5.x to 6.x is a smooth process and native support for JSON and XML in Hibernate 6.x makes it easier to handle data better suited to non-relational formats.
- The migration from Hibernate 5.x to 6.x requires minimal changes, mainly focused on the columnDefinition for storing arrays and collections as JSON or XML.
- With these enhancements, Hibernate continues to evolve as a robust ORM framework, making it easier for developers to work with complex data types in modern applications.
