Hibernate does not automatically create table in mysql

I'm studying Spring with a bit of Hibernate, where I stopped in a situation I can not get through.

I've set up the hibernate code for creating tables in the database, but when I run the application it does not create.

My template class:

@Entity

@Table(name="cliente")

public class Cliente {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;

    private String nome;


    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }
}

My properties:

server.port=${port:8080}
spring.datasource.url=jdbc:mysql://localhost:3306/clientesdb
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.jpa.hibernate.ddl-auto = update

MySQL without a password.

Am I doing something wrong?
