This library provides a set of additional bean validation (JSR 349 formerly JSR 303) constraints and validators. You find the constraints in the package de.malkusch.validation.constraints:

• @Age: The Date must be in the past and at least that years old.
• @Adult: The Date must be at least 18 years old.
• @BIC: The String must be a valid BIC (Business Identifier Code) address.
• @IBAN: The String must be a valid IBAN (International Bank Account Number) address.
• @BitcoinAddress: Validates a bitcoin address.
• @TLD: The String is a Top Level Domain.
• @Domain: The String has to be a Domain.
• @IPv4: The String has to be an IPv4 address.
• @ContentType: The Spring MultipartFile must match a ContentType. You have to provide javax.mail for the matching.
• @Image: The Spring MultipartFile must be an image.
• @NotEmptyBlob: The Blob must not be empty (but can be null).
• @Country: The String has to be a well formed ISO-3166-1 alpha-2 country code.
• @EqualProperties: The bean has properties with equal values (e.g. two identical passwords).
• @ISBN: The String has to be an ISBN (International Standard Book Number).

Some constraints require further dependencies. If you want to use them you have to provide those dependencies:

• de.malkusch.validation.constraints.upload.* requires org.springframework.web and javax.mail.mail.

de.malkusch.validation.validator.jsr349 extends some JSR-349 built-in constraints with validators for additional types:

• SizeValidatorForMultipartFile: Validates a @Size constraint against a Spring MultipartFile.
• PastValidatorFor…: Validates a @Past constraint against java.time (JSR 310: Date and Time API) objects.
• FutureValidatorFor…: Validates a @Future constraint against java.time (JSR 310: Date and Time API) objects.

If you want to use these validators you have to include the mapping resource META-INF/validation/mapping.xml. This can be done by preferably create the file META-INF/validation.xml and add that mapping or you do it programmatically with Configuration.addMapping(java.io.InputStream):

<?xml version="1.0" encoding="UTF-8"?>
<validation-config
    xmlns="https://jboss.org/xml/ns/javax/validation/configuration"
    xmlns:xsi="https://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="https://jboss.org/xml/ns/javax/validation/configuration validation-configuration-1.1.xsd">
    
    <constraint-mapping>META-INF/validation/mapping.xml</constraint-mapping>
</validation-config>
