Input JSON to convert it into a Spring Boot JPA schema!

- Project initial setup - When starting a new Spring Boot project and needing to set up the database schema, define the data model in JSON format and use this application to automatically generate JPA entity classes and related settings. - Converting existing data models to JPA - When needing to convert existing JSON-based data models to Spring Boot JPA, input the JSON data model definition to automatically generate Spring Boot JPA entities and mappings, and convert existing models to fit the JPA environment. - Synchronizing API documentation with schema - When needing to synchronize data models provided in API documentation with Spring Boot JPA schema, obtain the data model in JSON format from the API documentation and use this application to convert the model into JPA entities to automatically update the database schema. - Automatic code generation - When needing to maintain consistency between database models and JPA entities in large projects, input the database structure defined in JSON format to automatically generate JPA entities and related settings, maintain code consistency, and reduce manual writing errors. - Reusing data models across projects - When needing to use common data models in multiple Spring Boot projects, convert the common data model defined in JSON format into JPA entities to efficiently reuse the same data model across different projects.
