If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session. package com.journaldev.hibernate.model; import javax.persistence.

Today we will look into Session important methods for saving and updating data in tables – save, save Or Update, persist, update and merge. FIELD) public class Address package com.journaldev.hibernate.main; import org.hibernate. Generic Generator; import org.hibernate.annotations. Parameter; @Entity @Table(name = "ADDRESS") @Access(value=Access Type. Transaction; import com.journaldev.hibernate.model. This operation adds the entity object to persistent context and further changes are tracked and saved when transaction is committed. package com.journaldev.hibernate.main; import org.hibernate. Hibernate update should be used where we know that we are only updating the entity information. ***** Notice that first employee object is inserted, then at the time of transaction commit, update query is executed to update the name value. Hibernate save Or Update results into insert or update queries based on the provided data. Id=166 Hibernate: insert into ADDRESS (address_line1, city, zipcode, emp_id) values (?

After committing save Or Update transaction ***** 11. Id=166 Hibernate: update ADDRESS set address_line1=?

Second difference is that we can use method only within the boundary of a transaction, so it’s safe and takes care of any cascaded objects. Hibernate Util; public class Hibernate Persist Example Hibernate: insert into EMPLOYEE (emp_name, emp_salary) values (?

If the object properties are changed before the transaction is committed or session is flushed, it will also be saved into database. Employee persist called with transaction, id=158, address id=158 Hibernate: insert into ADDRESS (address_line1, city, zipcode, emp_id) values (? package com.journaldev.hibernate.main; import org.hibernate.

You also need to add an annotation processor so that spring can process the package com.javarticles.spring.hibernate; import

This will automatically provide the method with a transaction so we don’t have to explicitly manage it.

The returned object is part of persistent context and tracked for any changes, passed object is not tracked.
