Answer
Java Bean Validation ensures input meets certain constraints before processing.
In Spring, you can use annotations like @Valid in a controller to validate input data against Java Bean constraints. For example, if a user's email must not be blank, you can add @NotBlank to the email field. When a request is made, Spring checks these annotations and rejects requests that don't meet the criteria, preventing invalid data from reaching deeper layers of the application.
