[Spring] AutoConfiguration Magic Data JPA

Java Web Application with Spring and Hibernate (12)

/ JPA /

• We added Data JPA and H2 dependencies:
  • Spring Boot Auto Configuration does some magic:
    • Initialize JPA and Spring Data JPA frameworks
    • Launch an in memory database(H2)
    • Setup connection from App to in-memory database
    • Launch a few scripts at startup (example: data.sql)
• Remember - H2 is in memory database
  • Does NOT persist data
  • Great for learning
  • BUT NOT so great for production
  • Let’s see how to use MySQL next!
