What is the significance of the @Valid annotation in a method signature within a Controller?
- It enables request parameter validation for all parameters of the annotated method.
- It specifies that the method should be called only if validation passes.
- It indicates that the method returns a validated response.
- It has no specific significance within a Controller.
The @Valid annotation in a method signature within a Controller enables request parameter validation for all parameters of the annotated method. This ensures that incoming request parameters are validated against defined constraints before the method is executed. Option 2 is not accurate as the @Valid annotation itself doesn't control whether the method is called or not. Option 3 is incorrect as @Valid is related to input validation, not response validation. Option 4 is also incorrect.
