Custom Annotation in Spring Boot:
A custom annotation in Spring Boot is a user-defined Java annotation that you can apply to classes, methods, fields, or other program elements. These annotations serve as markers that convey additional information about the elements they annotate. In the context of validation, custom annotations are often used to define specific constraints and rules for validating data within your Spring Boot application.
For example, you can create a custom annotation like @MyCustomValidation to signify that a field should adhere to certain rules defined by your application. Custom annotations are particularly useful for encapsulating domain-specific validation requirements and making your code more expressive and self-documenting.
Custom Validation in Spring Boot:
Custom validation in Spring Boot refers to the process of enforcing application-specific rules and constraints on data. It involves defining custom validation logic and associating it with custom annotations. This allows you to validate data based on your unique business requirements.
