In a Spring Boot application, how can you validate a field based on multiple conditions or constraints?
- Using only the @NotNull annotation
- Combining multiple annotations like @Min, @Max, and @Pattern
- Creating a custom validator class for each condition
- Using JavaScript to validate the field on the client-side
To validate a field based on multiple conditions or constraints in a Spring Boot application, you can combine multiple annotations like @Min, @Max, and @Pattern. These annotations allow you to define various rules for a single field. Creating a custom validator class for each condition (Option 3) would be cumbersome and is not the recommended approach.
