Week 7 of #100DaysOfCode: Back to the Fundamentals
TL;DR: A coder refocuses on fundamentals of Spring after busy weeks, revisiting DI, AOP, IoC, Spring Security, logging, and design principles while preparing for exams and interviews.
The author returns to core Spring concepts (POJOs, DI, interfaces, AOP, modules, WebFlux) to deepen understanding. They balance study with career prep, updating their CV, applying for backend roles, and attempting an AI-powered mock interview. Logging in Spring Boot takes center stage, covering the purpose of loggers, LoggerFactory usage, and logging best practices over ad-hoc prints. Even without shipping a new project, the week emphasizes learning depth to build secure, scalable, and maintainable apps.
Question for the room: What Spring concept did you recently deepen, and how did you apply it to a real project at work or in a side project?
