What is the difference between concern and cross-cutting concern in Spring AOP?

Concern is behavior which we want to have in a module of an application. Concern may be defined as a functionality we want to implement to solve a specific business problem. E.g. in any eCommerce application different concerns (or modules) may be inventory management, shipping management, user management etc.

Cross-cutting concern is a concern which is applicable throughout the application (or more than one module). e.g. logging , security and data transfer are the concerns which are needed in almost every module of an application, hence they are termed as cross-cutting concerns.
