我正在尝试制作一个简单的持久性示例，使用 JPA 和 Hibernate 作为提供程序。我正在使用MySQL作为数据库。但是我收到此错误：

这是我的代码

1） Test.java

public class Test {

public static void main(String[] args){
    EntityManagerFactory emf = Persistence.createEntityManagerFactory("ExampleJPA");
    EntityManager em = emf.createEntityManager();

    em.getTransaction().begin();
    for(int i = 1; i < 11; i++)
    {

        Person p = new Person();
        p.setName("pessoa " + i);
        em.persist(p);
    }
    em.getTransaction().commit();
    em.close();
}
}

2）人.java

public class Person {

private int id;
private String name;

public int getId() {
    return id;
}

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

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}
