Exception in thread "main" org.hibernate.exception.SQLGrammarException: could no

最近学习Hibernate框架  遇到了如下问题  看了各种大神的相关解答，依旧没能解决我的问题，希望高手指点下迷津。以下是我的相关代码：
Person2.java:
import java.util.ArrayList;
import java.util.List;import javax.persistence.*;@Entity
// 声明为实体类
@Table(name = "tb_person2")
// 声名表名
public class Person2 { @Id
// 声明主键
@GeneratedValue(strategy = GenerationType.AUTO)
// 声明主键生成规则

private Integer id; private String name;

@OneToMany(fetch = FetchType.EAGER, targetEntity = Email.class, cascade = {
CascadeType.PERSIST, CascadeType.REMOVE, CascadeType.MERGE,
CascadeType.REFRESH })
// 一对多配置，并配置列关系
@JoinColumns(value = { @JoinColumn(name = "person id", referencedColumnName = "id") })
@OrderBy(value = "email desc")
// 配置排序关系

private List<Email> emails = new ArrayList<Email>(); public List<Email> getEmails() {
return emails;
} public void setEmails(List<Email> emails) {
this.emails = emails;
} public Integer getId() {
return id;
} public void setId(Integer id) {
this.id = id;
} public String getName() {
return name;
} public void setName(String name) {
this.name = name;
}
}
Email.java
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;@Entity
@Table(name = "tb_email")
public class Email { @Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id; private String email; public String getEmail() {
return email;
} public void setEmail(String email) {
this.email = email;
} public Integer getId() {
return id;
} public void setId(Integer id) {
this.id = id;
}}

}
} // 删除 Person 对象，会自动级联删除属于它的 Email 数据库记录
session.delete(person); session.getTransaction().commit();

}
在数据库中 只插入了person2表  而email表插不进  不知怎么回事？？、hibernate异常
