When we have relationship between entities, we need to define how the different operations will affect the other entity. This is done by cascading and there are different types of it. Note that Hibernate CascadeType enum constants are different from JPA javax.persistence.CascadeType, so we need to use the Hibernate CascadeType and Cascade annotations for mappings.
Commonly used cascading types as defined in CascadeType enum are:
None:This is not a type but when we don’t define any cascading then no operations in parent affects the child.
ALL:Cascades save, delete, update, evict, lock, replicate, merge, and persist.
SAVE_UPDATE:Cascades save and update, available only in Hibernate.
DELETE:Corresponds to the Hibernate native DELETE action, only in Hibernate.
DETATCH, MERGE, PERSIST, REFRESH and REMOVE – They have similar operations.
LOCK:This corresponds to the Hibernate native LOCK action.
REPLICATE:This corresponds to the Hibernate native REPLICATE action.
