These are foremost the constraints defined by the Bean Validation specification (see Section 2.3.1, “Bean Validation constraints”).
In addition to the constraints defined by the Bean Validation API, Hibernate Validator provides several useful custom constraints which are listed below.
In Java JDK, two built-in XML parsers are available – DOM and SAX, both have their pros and cons.
Here’s few examples to show how to create, modify and read a XML file with Java DOM, SAX, JDOM.
In order to update the server modules for Bean Validation API and Hibernate Validator to the latest and greatest, the patch mechanism of Wild Fly can be used. Final, support for Java 9 and the Java Platform Module System (JPMS) is experimental. Size; public class Car package org.hibernate.validator.referenceguide.chapter01; import constraint Violation = constraint Violations.iterator().next(); assert Equals( "Not enough towing capacity.", constraint Message() ); assert Equals( "towing Capacity", constraint Property Path()String() ); constraint Violation = constraint Violations.iterator().next(); assert Equals( "Gear is not providing enough torque.", constraint Message() ); assert Equals( "gear Box", constraint Property Path()String() );package org.hibernate.validator.referenceguide.chapter02.containerelement.nested; import Class-level constraints are useful if the validation depends on a correlation between several properties of an object.
There are no JPMS module descriptors provided yet, but Hibernate Validator is usable as automatic modules. When a class implements an interface or extends another class, all constraint annotations declared on the super-type apply in the same manner as the constraints specified on the class itself.
