Question

Given the following class

public class Website {

    @NotNull
    String owner:

    @ValidUrl
    String url;

}

When we validate that (e.g. using @Valid) and if Website.url does not respect my custom @ValidUrl constraint we’ll get an constraint violation (e.g. “url is unreachable”).

I was wondering if it is possible to ignore that validation if the user wants to.

Steps:

1. Validate form for the 1st time
2. Throw constraint violation and show it to the user
3. User chooses “I know, add it anyway” and re-submit
4. Validate form for the 2nd time, validating everything except @ValidUrl

Answer 1

You can do this by a combination of using validation groups and programmatic validation.
