我想连接hibernate和mysql。我尝试了所有的方法，但我仍然得到这个错误。我正在使用hibernate版本。

=>这是我的hibernate.cfg.xml

<?xml version='1.0' encoding='utf-8'?> 
<!DOCTYPE hibernate-configuration PUBLIC

=>这是我的休眠Map

<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC

    <property name="prenomPersonne" type="string" not-null="true" />

  </class>
</hibernate-mapping>

=>最后我的班级人员

public class Personnes {

  private Integer idPersonne;
  private String nomPersonne;
  private String prenomPersonne;

  public Personnes(String nomPersonne, String prenomPersonne) {
    this.nomPersonne = nomPersonne;
    this.prenomPersonne = prenomPersonne;

  }

  public Personnes() {
  }

  public Integer getIdPersonne() {
    return idPersonne;
  }

  public String getNomPersonne() {
    return nomPersonne;
  }

  public String getPrenomPersonne() {
    return prenomPersonne;
  }

  public void setIdPersonne(Integer integer) {
    idPersonne = integer;
  }

 And,thanks for responding as quickly as possible.

  public void setPrenomPersonne(String string) {
    prenomPersonne = string;
  }

public void setNomPersonne(String string) {
    // TODO Auto-generated method stub

}

}
