如何在Java-EE中使用hibernate创建ManyToMany关系？

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

    private String name;

    @ManyToMany(cascade = CascadeType.ALL)
    @JoinTable(name = "student_course",
            joinColumns = @JoinColumn(name = "student_id"),
            inverseJoinColumns = @JoinColumn(name = "course_id"))
    private Set<Course> courses = new HashSet<>();

    // 省略构造方法、getter和setter
}

@Entity
@Table(name = "course")
public class Course {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String name;

    @ManyToMany(mappedBy = "courses")
    private Set<Student> students = new HashSet<>();

    // 省略构造方法、getter和setter
}

<hibernate-configuration>
    <session-factory>
        <!-- 数据库连接配置 -->
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">password</property>

        <!-- Hibernate配置 -->
        <property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
        <property name="hibernate.show_sql">true</property>
        <property name="hibernate.hbm2ddl.auto">update</property>

        <!-- 实体类映射 -->
        <mapping class="com.example.Student"/>
        <mapping class="com.example.Course"/>
    </session-factory>
</hibernate-configuration>

public class Main {
    public static void main(String[] args) {
        // 创建SessionFactory
        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();

        // 创建Session
        Session session = sessionFactory.openSession();
        session.beginTransaction();

        // 创建学生对象
        Student student1 = new Student();
        student1.setName("Alice");

        Student student2 = new Student();
        student2.setName("Bob");

        // 创建课程对象
        Course course1 = new Course();
        course1.setName("Math");

        Course course2 = new Course();
        course2.setName("English");

        // 建立关联关系
        student1.getCourses().add(course1);
        student1.getCourses().add(course2);

        student2.getCourses().add(course1);

        // 保存学生和课程对象
        session.save(student1);
        session.save(student2);
        session.save(course1);
        session.save(course2);

        session.getTransaction().commit();
        session.close();
        sessionFactory.close();
    }
}
