Hibernate注释OnDelete是否有等效的JPA2注释?
Is there an equivalent JPA2 annotation for the Hibernate annotation OnDelete?
推荐答案
尝试@OneToMany(cascade=CascadeType.Delete)
.因此,级联将由orm(休眠)而不是数据库处理.如果要在数据库中生成一个层叠,则唯一的休眠特定注释是唯一的方法.
Try @OneToMany(cascade=CascadeType.Delete)
. Thus the cascade will be handled by the orm (hibernate), and not the database. If you want to have a cascade generated in the DB, the hibernate-specific annotation is the only way.
