Hibernate update not updating
package com.journaldev.hibernate.util; import org.hibernate.
If you are facing this issue with your Windows 10/8/7 laptop, then you may try some of these troubleshooting steps. It is quite possible that some rogue device driver may be preventing your laptop from going into the Hibernation mode. Compare it with XML based configurations, you will find them very similar. Our test program is just like xml based configuration, we are just using the new classes for getting Hibernate Session and saving the model objects into database. That’s it for one to many mapping in hibernate using annotation in model classes. Hibernate Annotation Util; public class Hibernate One To Many Annotation Main Hibernate Annotation Configuration loaded Hibernate Annotation service Registry created Session created Hibernate: insert into CART (name, total) values (? ) Hibernate: insert into ITEMS (cart_id, item_id, item_total, quantity) values (? ) Hibernate: insert into ITEMS (cart_id, item_id, item_total, quantity) values (? If not, you may want to update your device drivers before you proceed.
You may also need to update your drivers for your Video Card.
Cart ID=6 Closing Session Factory Notice that Hibernate is using Update query to set the cart_id in ITEMS table. Service Registry; public class Hibernate Annotation Util Since we don’t have xml based mapping files, all the mapping related configurations will be done using JPA annotations in the model classes.
Table; @Entity @Table(name="CART") public class Cart1 package com.journaldev.hibernate.model; import javax.persistence.
A cart can have multiple items, so here we have one to many mapping.
We will use Cart-Items scenario for our hibernate one to many mapping example. Hibernate Util; public class Hibernate One To Many Main Hibernate Configuration loaded Hibernate service Registry created Session created Hibernate: insert into CART (total, name) values (? ) Hibernate: insert into ITEMS (item_id, item_total, quantity, cart_id) values (?
If updating your drivers resolves the issue, well and good, else you may try the next steps.
