On update cascade on delete cascade With my current setup, hibernate doesn't seem to set field tastockid. How Can I make sure that hibernate recognised tastockid as the foreign key, and sets this field when saving TaStock? 2017-9-2  Hibernate Cascade Types. Now lets understand what is cascade in hibernate in which scenario we use it. Apart from JPA provided cascade types, there is one more cascading operation in hibernate which is not part of the normal set above discussed, called “orphan removal“. This removes an owned object from the database when it’s removed from. 2013-5-28  Hibernate provides the facility to update the entity for those database values which are generated at insert or row update time. @Generated belongs to org.hibernate.annotations. @Generated is used at property level. There are different GenerationTime. GenerationTime.INSERT GenerationTime.INSERT updates the entity at insert time.

HowToDoInJavaBy Lokesh Gupta Filed Under: Hibernate

Hibernate is an object-relational mapping (ORM) library for the Java language, providing a framework for mapping an object-oriented domain model to a traditional relational database. This means you are not required to build and execute SQL queries for interaction with database. You just have to instruct hibernate for that by calling hibernate APIs and hibernate will create and execute those SQL queries on behalf of you.

In this hibernate tutorial, I am giving example of inserting data in a single table. We have an object in application i.e. Employee. We want to store it in database. Employee class has following attributes:

• employee id – Integer
• email – String
• first name – String
• last name – String

It can have more fields, but I am taking only four to make example concrete.

1. Hibernate entity class

Hibernate talks with Java POJO classes which are marked as hibernate entities. To convert a Java class into entity, we need to apply @Entity annotation on it. There are other hibernate annotations like @Table, @Column and @Id etc which help in mapping entity fields to database table and columns.

Employee entity class looks like below after applying the annotations. /windows-81-pro-product-key-generator-kickass.html.

2. Hibernate configuration

Next step is to configure hibernate in “hibernate.cgf.xml” file. This file contains all available entities in system and database connection meta-data.

3. Hibernate SessionFactory

Now hibernate configuration is on place, we have to build the hibernate session factory. Session factory is used to obtain the connection of database and various activities like commit and rollback.

4. Hibernate insert query example

Finally we will use this hibernate session factory to execute insert query to save employee in database.

Lets verify the data in database.

5. Troubleshooting

1. Please ensure to add hibernate and mysql driver dependencies in project. In maven these are as below:
2. Verify that hibernate.cgf.xml file is present and has valid database meta-data.
