Easy Spring Part 1. Understanding Spring Framework and DI, AOP

Lecture Topics 📖

Course Target Audience/Course Purpose 🙆‍♀️

Types of students considered by knowledge sharers

• People who lack the concept of frameworks
• For those new to Spring
• A person who has written code but cannot explain why it is done that way

Students' Concerns & Solutions

• When you're asked Spring-related questions in a technical interview, do you just barely manage to answer with what you've memorized?
• Are you wondering why your code is running, even though it's working? Or are you having trouble understanding the error your code is causing?
• We will guide you through the optimal framework learning method of understanding what you need to understand and memorizing what you need to memorize.

Changes in students after attending the lecture

• You can set up your first project and start developing.
• After attending the lecture, you will be able to understand the life cycle of beans including DI.
• You can distinguish between core and cross-cutting concerns, and modularize cross-cutting concerns.
• I can confidently explain the role and operation of the Spring Framework.

Lecture Features ✨

This lecture unravels the framework through real-life experiences unrelated to programming. If you've struggled to understand complex code, how about your understanding of frameworks in real life? The benefits of DI, obvious to anyone who's ever rented an appliance, and the understanding of AOP, accessible to anyone who hates cleaning but needs it, will help you naturally embrace Spring's concepts, which were once considered difficult.

We have also organized the content to make it as easy to understand as possible using tables and images to explain what we want to explain.

What you'll learn 📚

True~Easy Spring is divided into 4 parts, and this lecture is about Part 1: SpringFramework concepts and DI, AOP .

• Part 1 covers the concepts of Spring Framework and its most important features, DI and AOP. You should be familiar with Java grammar before reading this.
• Part 2 focuses on how to create business logic. This uses Spring Data JPA, requiring prior knowledge of simple SQL writing skills and the content of the previous part.
• Part 3 covers building a Spring @MVC and REST-based web application. Basic web knowledge is helpful, and familiarity with the content in the previous part is also required.
• Part 4 adds security elements to the web application created in Part 3.

It will take some time for the next part to be registered. It may not be suitable for those who plan to take the entire course consecutively.

Expected Questions Q&A 💬

Q. Will I be able to develop using Spring if I take this course (Part 1)?
A. Part 1 covers only the most fundamental concepts required for the Spring Framework to function, including dependency injection and AOP. While you can certainly use this material for self-study, we recommend completing Part 3 if possible.

Q. What kind of environment do I need to take the course?
A. Development using the Spring Framework doesn't depend on any specific operating system or development tools. However, the course will be conducted using Intellij on a Mac. While the community edition of Intellij is available, it does have some minor inconveniences, so we recommend using the enterprise version if possible. The 30-day trial version is completely free for course completion.

Q. If I take the course, will I be able to develop applications using Spring?
A. Spring is a framework that helps developers develop applications more easily. By diligently completing the course, even a novice with an idea can create a compelling presentation using PowerPoint. Just as that can help you create compelling presentations, you'll be able to use the Spring Framework to transform your ideas into compelling applications.

Things to note before taking the course 📢

Practice environment

• Operating System and Version (OS): Windows, macOS, etc. OS that can install JDK and the IDE below
• Tools used: VSCode and Eclipse-based STS are completely free to use, while IntelliJ requires a separate license (though using the community version is a bit inconvenient, and a 30-day trial is available), JDK 17 or higher.
• PC specifications: 2GB or more of free memory, 8GB or more of total system memory, 4GB or more of HDD space
• The process is carried out using IntelliJ on macOS.

Learning Materials

• The materials are shared and updated through the blog (https://goodteacher.tistory.com/).
• If practical training is required, the final project results will be shared. However, we encourage you to create your own if possible.
