Hibernate is not mapping classes

Question

The Hibernate I am using is not generating the tables automatically

My Persistence.xml file

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="WebServiceRest" transaction-type="RESOURCE_LOCAL">

        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <class>br.com.model.Departamento</class>

        <properties>
            <!-- Url do banco Mysql  -->
            <property name="hibernate.connection.url" value="jdbc:mysql://localhost/william" />
            <!-- Driver Conector JDBC do Mysql -->
            <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
            <!-- Usuário do banco -->
            <property name="hibernate.connection.username" value="root" />
            <!-- Senha do banco -->
            <property name="hibernate.connection.password" value="root" />
            <!-- Mapeia todas a classes com anotações  -->
            <property name="hibernate.archive.autodetection" value="class" />
            <!-- Debuga as querys do Sql -->
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />
            <property name="hbm2ddl.auto" value="update" />
        </properties>

    </persistence-unit>
</persistence>

My Class with the Notes

package br.com.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Table;
import javax.persistence.Id;

@Entity
@Table(name="departamento")
public class Departamento {

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id")
    private int Id;

    @Column(name="nome")
    private String Nome;

    public int getId() {
        return Id;
    }

    public void setId(int id) {
        Id = id;
    }

    public String getNome() {
        return Nome;
    }

    public void setNome(String nome) {
        Nome = nome;
    }



}

Obs I’m not using Maven

Answer 1

Man, in your persistence I’m not seeing the Mayor...

org.hibernate.jpa.Hibernatepersistenceprovider

add it and take a better look at this link

https://www.caelum.com.br/apostila-java-web/uma-introducao-pratica-ao-jpa-com-hibernate/#configuring-o-jpa-com-as-propriedades-do-banco

from Caelum that explains right how to implement your conf for the use of JPA.

Friend try to change the following property

<property name="hbm2ddl.auto" value="update" /> 

for

<property name="hibernate.hbm2ddl.auto" value="create"/>
