JPA Specifications

JPA Specifications are a way for developers to create flexible and dynamic database queries in Java applications. Instead of writing static SQL or fixed methods, specifications allow you to define search criteria programmatically, such as filtering users by age or location. These specifications can be combined and reused, making complex queries easier to manage. Essentially, they serve as a blueprint or set of rules that tell the database what data to retrieve, ensuring code remains modular, readable, and adaptable to changing requirements.
