如何删除Hibernate中多对多关系中的实体

// 实体类之间的多对多关系
@Entity
public class EntityA {
    @Id
    private Long id;

    @ManyToMany
    @JoinTable(name = "a_b",
            joinColumns = @JoinColumn(name = "a_id"),
            inverseJoinColumns = @JoinColumn(name = "b_id"))
    private Set<EntityB> entitiesB;

    // 省略其他属性和方法
}

@Entity
public class EntityB {
    @Id
    private Long id;

    @ManyToMany(mappedBy = "entitiesB")
    private Set<EntityA> entitiesA;

    // 省略其他属性和方法
}

// 删除多对多关系中的实体
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();

EntityA entityA = session.get(EntityA.class, entityId);
EntityB entityB = session.get(EntityB.class, entityId);

entityA.getEntitiesB().remove(entityB);
entityB.getEntitiesA().remove(entityA);

session.delete(entityA);
session.delete(entityB);

tx.commit();
session.close();
