Java String URL Validation-CodePudding

I am trying to validate s String url in my java application using @Pattern annotation of the javax validation library.

@Pattern(message = "Must be a valid URL", regexp = "https?:\\/\\/(www\\.)?[-a-zA-Z0-9@:%._\\ ~#=]{1,256}\\.[a-zA-Z0-9()]{1,6}\\b([-a-zA-Z0-9()@:%_\\ .~#?&//=]*)")

When i submit a url in the url in this format; https://www.test.com it is successful but url in this format https://api-apps.testapp.systems/test-service/v1/test, it fails the validation.

The issue is with the .com The same url with .systems fail but with .com passes.

How can i make my regular expression allow all kinds of urls .com, .edu or .systems regardless ??

You can use the @URL Annotation or org.apache.commons.validator.UrlValidator to do that.

Example:

        UrlValidator crunchifyURLValidator = new UrlValidator();
        
        String url = "https://crunchify.com";
        if (crunchifyURLValidator.isValid(url)) {
            crunchifyLog("Hey. URL "   url   " is valid");
        } else {
            crunchifyLog("Hey. URL "   url   " is not valid");
        }

The issue was with the lenght of string permitted by the regexp for the TLD, which was {1,6}-- .[a-zA-Z0-9()]{1,6}\\b i expanded the range and it accommodated a longer TLD name.
