Starting with Maven to create database in Mysql

Question

Good morning, you guys! Can anyone help me? I’m a beginner, and I’m starting to do a Maven project, I’m trying to run the project and this giving error:

**INFO: HHH000400: Using dialect: org.hibernate.dialect.Mysqldialect Session factory cannot be created -> java.lang.Noclassdeffounderror: javax/validation/Validatorfactory Exception in thread "main" java.lang.Exceptionininitializererror at br.com.asdb.util.Hibernateutil.(Hibernateutil.java:25) At Testehibernate.main(Testehibernate.java:9) Caused by: java.lang.Noclassdeffounderror: javax/validation/Validatorfactory at java.base/java.lang.Class.getDeclaredMethods0(Native Method) at java.base/java.lang.Class.privateGetDeclaredMethods(Class.java:3334) at java.base/java.lang.Class.getMethodsRecursive(Class.java:3475) at java.base/java.lang.Class.getMethod0(Class.java:3461) at java.base/java.lang.Class.getMethod(Class.java:2193) at org.hibernate.cfg.beanvalidation.Beanvalidationintegrator.Integrate(Beanvalidationintegrator.java:113) at org.hibernate.Internal.SessionFactoryImpl.(Sessionfactoryimpl.java:292) at org.hibernate.boot.internal.Sessionfactorybuilderimpl.build(Sessionfactorybuilderimpl.java:471) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:728) at br.com.asdb.util.Hibernateutil.(Hibernateutil.java:21) ... 1 more Caused by: java.lang.Classnotfoundexception: javax.validation.Validatorfactory java.base/jdk.internal.Loader.BuiltinClassLoader.loadClass(Builtinclassloader.java:636) at java.base/jdk.internal.Classloaders$Appclassloader.loadClass(Classloaders.java:182) at java.base/java.lang.Classloader.loadClass(Classloader.java:519) ... 11 more

The pom.xml file ****

    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1:3306/drogaria

    <property name="hibernate.c3p0.idle_test_period">100</property>

    <mapping class="br.com.asdb.entidades.Pessoa" />

</session-factory>

The class Hibernateutil: ****package br.com.asdb.util;

import org.hibernate.Session; import org.hibernate.Sessionfactory; import org.hibernate.boot.registry.Standardserviceregistrybuilder; import org.hibernate.cfg.Configuration; import org.hibernate.service.Serviceregistry;

public class Hibernateutil {

private static final SessionFactory fabricaDeSessoes;

static {
    try {
    Configuration configuracao = new Configuration();
    configuracao.configure();

    ServiceRegistry registroServico = new StandardServiceRegistryBuilder()
            .applySettings(configuracao.getProperties()).build();

    fabricaDeSessoes = configuracao.buildSessionFactory(registroServico);
    }
    catch(Throwable ex) {
        System.err.println("A fábrica de sessões não pode ser criada -> " + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static Session getSession() {
    return fabricaDeSessoes.openSession();
}

}**

And this is the file Hibernate.cfg.xml ****

    <property name="hibernate.c3p0.idle_test_period">100</property>

    <mapping class="br.com.asdb.entidades.Pessoa" />
