Module outcome
Know the core Java, HTTP, SQL, and build-tool concepts needed to follow the Spring Boot modules.
Mental model
Spring Framework automates object construction and infrastructure wiring; Module 0 checks that you can read ordinary Java, HTTP, SQL, and build files well enough to recognize what Boot later automates.
Module checkpoint
Readiness checkpoint
Confirm Java, build-tool, HTTP client, Docker, and database basics before starting the first Boot app.
- Explains the main Java concepts Spring relies on
- Verifies Java 21 and the build wrapper
- Explains the HTTP and SQL boundaries the later API will use
