@Validated annotation is a class-level annotation that we can use to tell Spring to validate parameters that are passed into a method of the annotated class. and. @Valid annotation on method parameters and fields to tell Spring that we want a method parameter or field to be validated.
The Java Bean Validation's @Valid constraint annotation makes sure that when an object is validated, the validation recurses to all fields that are annotated with @Valid . This makes it really easy to perform the usually complex task of validating entire object graphs.
Particular example: use a BindingResult object as an argument for a validate method of a Validator inside a Controller.
Then, you can check this object looking for validation errors:
validator.validate(modelObject, bindingResult); if (bindingResult.hasErrors()) { // do something } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
