JPA in Spring


=============


JPA (Java Persistence API) in Spring simplifies database interactions by providing a standard way to map Java objects to database tables and vice versa.





Common Configurations for JPA





spring.datasource


This configuration specifies the database connection details.


spring.datasource.url=jdbc:mysql://localhost:3306/mydatabase spring.datasource.username=root

spring.datasource.password=password

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver





spring.jpa


These properties configure the behavior of JPA.


spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

spring.jpa.show-sql=true

spring.jpa.hibernate.ddl-auto=update





Purpose


spring.datasource is used to specify the database connection details, while spring.jpa configures JPA-related behavior such as SQL dialect and DDL auto-generation.
