Data processing: At the service layer, the business logic can be handled to process, validate, and transform data, ensuring its accuracy and integrity.
Transaction management: The service layer is typically used to control the boundaries of transactions, ensuring that a series of operations either all succeed or all fail and are rolled back.
Permission control: Service layer can verify and control user permissions to ensure that users can only access resources they are authorized to access.
Cache management: The service layer can manage caching to enhance system performance and response speed.
Exception handling: The service layer can handle and catch exceptions to ensure the stability and reliability of the system.
A third-party service can be called in the service layer to interact with external services or APIs, handling and encapsulating the data returned from external interfaces.
Logging: The service layer can record the system’s operational logs for monitoring and analysis purposes.
Encapsulation of business logic: The service layer can encapsulate business logic as services, providing them for the controller layer to call, achieving code modularity and reusability.
