Hibernate – Most Important Methods:
buildSessionFactory() : Create a SessionFactory using the properties and mappings in this configuration. The SessionFactory will be immutable, so changes made to this Configuration after building the SessionFactory will not affect it.
openSession() : SessionFactory.openSession() always opens a new session that you have to close once you are done with the operations.
beginTransaction() : Begin a unit of work and return the associated Transaction object. If a new underlying transaction is required, begin the transaction. Otherwise continue the new work in the context of the existing underlying transaction.
commit() : Commit this transaction.
close() : End the session by releasing the JDBC connection and cleaning up.
load(Class clazz,serializable id) : Return the persistent instance of the given entity class with the given identifier, assuming that the instance exists.
get(Class clazz,serializable id) : Return the persistent instance of the given entity class with the given identifier, or null if there is no such persistent instance.
persist() : Make a transient instance persistent.
save() : Persist the given transient instance, first assigning a generated identifier.
saveOrUpdate() : Either save(Object) or update(Object) the given instance, depending upon resolution of the unsaved-value checks (see the manual for discussion of unsaved-value checking).
update() : Update the persistent instance with the identifier of the given detached instance.
merge() : Copy the state of the given object onto the persistent object with the same identifier.
evict() : Remove this instance from the session cache.
clear() : Completely clear the session.
delete() : Remove a persistent instance from the datastore.
createQuery() : Create a Query instance for the given HQL query string.
list() : Return the query results as a List.
executeUpdate() : Execute the update or delete statement.
createCriteria() : Create Criteria instance for the given class (entity or subclasses/implementors)
createSQLQuery() : Create a SQLQuery instance for the given SQL query string.
getnamedQuery() : Create a Query instance for the named query string defined in the metadata.
