Crud Service

CrudService is the main abstraction for CRUD operations in DynamiaTools.

What it does

• Create, read, update, and delete entities.
• Centralize data access for CRUD views and application processes.
• Avoid repetitive repositories in standard scenarios.

Default implementation

The common implementation is JpaCrudService, based on JPA.

import org.springframework.stereotype.Service;
import tools.dynamia.crud.CrudService;

@Service
public class CustomerAppService {

    private final CrudService crudService;

    public CustomerAppService(CrudService crudService) {
        this.crudService = crudService;
    }

    public void activate(Long customerId) {
        Customer customer = crudService.find(Customer.class, customerId);
        customer.setActive(true);
        crudService.save(customer);
    }

    public List<Customer> findActiveCustomers() {
        return crudService.findAll(Customer.class, "active", true);
    }
}

Best practices

• Use CrudService from application services, not directly from complex controllers.
• Encapsulate business rules in Spring services.
• Keep entities clean and validated with Bean Validation.
• For advanced queries, combine CrudService with specialized query components.
