錯誤：'字段列表'中的未知列'DTYPE'

我正在嘗試使用JPA與Hibernate作爲提供程序進行持久性的簡單示例。我使用MySQL作爲數據庫。但我發現了這個錯誤：錯誤：'字段列表'中的未知列'DTYPE'

Hibernate: insert into person (NAME, DTYPE) values (?, 'person')

這裏我的代碼

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）Person.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; 
} 

}

3）持久性。 xml

<?xml version="1.0" encoding="UTF-8" ?> 
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/persistence    
http://java.sun.com /xml/ns/persistence/persistence_2_0.xsd" 
     version="2.0" xmlns="http://java.sun.com/xml/ns/persistence"> 

<persistence-unit name="ExampleJPA" transaction-type="RESOURCE_LOCAL">

     <property name="hibernate.show_sql" value="true"/> 
    </properties> 
</persistence-unit> 

</persistence>

4）Person.xml
