Hibernate用子对象删除父对象进行一对一映射

Question

我在数据库中有两个名为Student（作为父级）和StudentInfo（作为子级）的表，它们具有一对一的关系。当我删除Parent对象时，应该删除相关的子对象。

我的学生pojo：

@Entity
@Table(name = "student")
public class Student {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
    private String studentName;

    @OneToOne(cascade= CascadeType.REMOVE)
    @JoinColumn(name="id")
    private StudentInfo info;
    // getters and setters 
}

和我的StudentInfo pojo ..

@Entity
@Table(name = "studentInfo")
public class StudentInfo {

    @Id
    @GeneratedValue(generator = "newGenerator")
    @GenericGenerator(name = "newGenerator", strategy = "foreign", parameters = @Parameter(name = "property", value = "student"))
    private int id;
    private String mobileNo;

    @OneToOne
    @JoinColumn(name = "id")
    private Student student;
    // getters and setters 
}

当我对Student（父）执行删除操作时，只有父对象被删除但是子对象id没有被删除。我如何删除父和子？
