Starting from the part where the spring application is dropped as a jar and run with Java,
I liked the way it continued to show the benefits of DI while creating controllers, services, and repositories along with tests.
In that way, while implementing the MemberRepository interface to JDBC, JdbcTemplate, JPA, and Spring Data JPA,
I was able to confirm how convenient and essential DI and IoC are at the moment I learned AOP.

Thank you, Eungi Kim, for listening so diligently. ^^ For your information, H2 is not used in actual operating environments. It is used in simple testing environments. Thank you.
