Cross-Cutting Concerns

About

In the context of JPA within Spring applications, cross-cutting concerns refer to functionalities that are not directly part of your domain model or business logic, but are critical to the reliable, consistent, and maintainable operation of your persistence layer. These concerns span across multiple layers and modules and are often handled declaratively through annotations or framework configuration.

In software architecture, most features follow the core flow: input → business logic → data access. However, some features "cut across" these layers and are required regardless of what the application does. These include:

• Logging

• Security (e.g., authentication/authorization)

• Transaction Management

• Caching

• Error Handling

• Auditing

• Concurrency Control

• Performance Monitoring
