我现在已经创建了3个表。学生电话和学生电话
学生.java

@Entity
@Table(name = "STUDENT")
public class Student {
  private long studentId;
  private Set<Phone> studentPhoneNumbers = new HashSet<Phone>(0);

  @Id
  @GeneratedValue
  @Column(name = "STUDENT_ID")
  public long getStudentId() {
    return this.studentId;
  }

  public void setStudentId(long studentId) {
    this.studentId = studentId;
  }

  @OneToMany(cascade = CascadeType.ALL)
  @JoinTable(name = "STUDENT_PHONE", joinColumns = { @JoinColumn(name = "STUDENT_ID") }, inverseJoinColumns = { @JoinColumn(name = "PHONE_ID") })
  public Set<Phone> getStudentPhoneNumbers() {
    return this.studentPhoneNumbers;
  }

  public void setStudentPhoneNumbers(Set<Phone> studentPhoneNumbers) {
    this.studentPhoneNumbers = studentPhoneNumbers;
  }

}

电话.java

@Entity
@Table(name = "PHONE")
public class Phone {

  private long phoneId;
  private String phoneType;
  private String phoneNumber;

  @Id
  @GeneratedValue
  @Column(name = "PHONE_ID")
  public long getPhoneId() {
    return this.phoneId;
  }

  public void setPhoneId(long phoneId) {
    this.phoneId = phoneId;
  }

  @Column(name = "PHONE_TYPE", nullable = false, length=10)
  public String getPhoneType() {
    return this.phoneType;
  }

  public void setPhoneType(String phoneType) {
    this.phoneType = phoneType;
  }

  @Column(name = "PHONE_NUMBER", nullable = false, length=15)
  public String getPhoneNumber() {
    return this.phoneNumber;
  }

  public void setPhoneNumber(String phoneNumber) {
    this.phoneNumber = phoneNumber;
  }
}

请通读示例代码https://dzone.com/articles/java/hibernate/hibernate-example/hibernate-mapping-one-to-many-using-annotations-1.html?edition=515297
如何审核上述示例中的学生电话表?
