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.
