How do I configure JPA in my Spring application?

To configure JPA in your Spring application, you need to add the necessary dependencies, set up your application properties, and create an EntityManager.

What dependencies do I need to add?

You need to add 'spring-boot-starter-data-jpa' and your database driver, like 'mysql-connector-java' for MySQL.

Can you show me an example of application.properties?

Sure! Here's a basic example:

spring.datasource.url=jdbc:mysql://localhost:3306/yourdb
spring.datasource.username=root
spring.datasource.password=yourpassword
spring.jpa.hibernate.ddl-auto=update

This configures the database connection and JPA settings.

What is the purpose of 'ddl-auto'?

The 'ddl-auto' property controls the behavior of the database schema generation. Options include 'none', 'update', 'create', and 'create-drop'.
