JPA @onetomany 级联删除Many端

When we use JPA @oneToMany
if you remove a dependent object from a OneToMany collection it will not be deleted, JPA1.0 don’t support it itself, it requires that you explicitly call remove() on it.
In JPA2.0 ,you need do add “orphanRemoval” to “@OneToMany” ,
just like this:
@OneToMany(mappedBy = "A", orphanRemoval=true,cascade = CascadeType.ALL)
