您可以将您的@ManyToMany分成@一对多，多对一，并成立了级联样式如图所示的此处虽然问题使用Hibernate的会话，你可以使用JPA的EntityManager。或者使用新的JPA功能 @ElementCollection （仅JPA 2）来映射你的加入类。请参见这里如何。仅仅通过更换@ElementCollection Hibernate的@CollectionOfElements

You can split your @ManyToMany into a @OneToMany-ManyToOne and set up a cascading style as shown here Although the question uses Hibernate's session, you can use JPA EntityManager. Or use the new JPA feature @ElementCollection (Only JPA 2) to map your joined class. See here how to. Just replace Hibernate's @CollectionOfElements by @ElementCollection
