How to achieve automatic table generation in Hibernate?

To enable Hibernate to automatically generate tables, you can accomplish this by setting the property hibernate.hbm2ddl.auto in the configuration file to create or update. The specific steps are as follows:

1. Add the following properties in the Hibernate configuration file (usually hibernate.cfg.xml):

<property name="hibernate.hbm2ddl.auto">create</property>

Either

<property name="hibernate.hbm2ddl.auto">update</property>

1. When the “create” attribute is set, Hibernate will delete and recreate the table every time it is started, whereas when the “update” attribute is set, Hibernate will only update the existing table structure without deleting any data in the table.
2. Running your application will cause Hibernate to automatically generate the corresponding database table structure based on the mapping relationships of your entity classes.

It is important to note that when using Hibernate to generate tables, it is not recommended to use the create or update properties in a production environment, as this may result in data loss or inconsistent table structures. It is suggested to use them during the development phase and then manually write database table structure scripts after development is completed.
