@Entity
@Table(name = "your_table_name")
public class YourEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(columnDefinition = "json")
    private String jsonData;

    // Getters and Setters
}

public interface YourRepository extends JpaRepository<YourEntity, Long> {

}

@Service
public class YourService {
    private final YourRepository repository;

    public YourService(YourRepository repository) {
        this.repository = repository;
    }

    public YourEntity saveJson(String jsonData) {
        YourEntity entity = new YourEntity();
        entity.setJsonData(jsonData);
        return repository.save(entity);
    }
}

@RestController
public class YourController {
    private final YourService service;

    public YourController(YourService service) {
        this.service = service;
    }

    @PostMapping("/your-endpoint")
    public YourEntity saveJson(@RequestBody String jsonData) {
        return service.saveJson(jsonData);
    }
}
