I'm trying to create tables automatically by hibernate, but I'm not succeeding.
The hibernate libraries are correct. the mysql connector is referenced as well as the hibernate libraries. I believe the problem is in the GeraTabela class.
I'm making the code available for help.
package br.com.teste;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class GeraTabela {
public static void main(String[] args) {
Configuration conf = new AnnotationConfiguration();
conf.configure();
SchemaExport se = new SchemaExport(conf);
se.create(true, true);
}
}
Employee Employee
package br.com.teste;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table
public class Funcionario {
private int id;
private String nome;
private String email;
private Cargo cargo = new Cargo();
public Cargo getCargo() {
return cargo;
}
public void setCargo(Cargo cargo) {
this.cargo = cargo;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Id
@GeneratedValue
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;
}
}

To work you have to right-click on the GenerateTab class to run as an application.
