java - Spring JPA and remove entries from @ManyToMany -

as touched on in following:

• cascade on delete using unidirectional many-to-many mapping
• how remove entity manytomany relationship in jpa (and corresponding join table rows)?
• jpa jpql: select items when attribute of item (list/set) contains item

when removing entries @manytomany mappings, there element of manual tweaking involved remove foreign keys.

i have been using own jpa crud years , have nice solution this: cruddao e.g. notedao.

but i've been impressed spring jpa , ability autogenerate cruds declaring interface , creating named namedquerys on @entity.

but how fix @manytomany remove problem? i'll have remove methods on crud expose "feature" of jpa.

i appear have solved using @preremove, noted in https://stackoverflow.com/a/14911910/1041691
