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

Lecture Topics 📖

Course Target Audience/Course Purpose 🙆‍♀️

Types of students that knowledge sharers think of

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

Students' Concerns & Solutions

• If you are asked a Spring-related question in a technical interview, do you just respond with what you have memorized?
• Are you wondering why your code is running, but not sure why? Or what error is occurring in your code?
• 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 get started developing.
• After taking 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 will tell you about the framework through stories that anyone would have experienced in real life that are not related to programming. If you had a hard time understanding the difficult code, how about understanding the framework that you feel in real life? The advantages of DI that anyone who has rented home appliances can feel, and the stories about AOP that anyone who hates cleaning but needs to clean can understand, will allow you to naturally accept the concept of Spring that was difficult.

I have also tried to organize the content in a way that is as easy to understand as possible, using tables and images to explain what I am trying to explain.

What you'll learn 📚

True~Easy Spring is largely 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 beforehand.
• Part 2 focuses on how to create business logic. For this, we will use Spring Data JPA and require prior knowledge of simple SQL writing skills and the contents of the previous part.
• Part 3 is a process of creating a web application based on Spring @MVC and REST. For this, basic web knowledge is recommended and the contents of the previous part are also required.
• Part 4 adds security elements to the web application we created in Part 3.

It will take some time for the next part to be registered. It may not be suitable for those who want to take the entire content 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 basic concepts required for the Spring Framework to operate, as well as DI and AOP. Of course, you can use this content to self-study the necessary content, but it is recommended that you take up to Part 3.

Q. What kind of environment is required to take the course?
A. Development using Spring Framework is not dependent on any special OS or development tool. However, the lecture will be conducted using Intellij in a Mac environment. In the case of Intellij, you can use the community edition, but there are some inconvenient parts, so it is recommended to use the enterprise version if possible. There is no problem in taking the lecture even if you use the 30-day trial version.

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. If you faithfully take the course, even if you have no skills, you can use PowerPoint to create a great presentation if you have an idea, and you will be able to use the Spring framework to turn your ideas into great applications.

Things to note before taking the class 📢

Practice environment

• Operating System and Version (OS): Windows, macOS, etc. JDK and the OS below that can be installed on the IDE
• Tools used: VSCode and Eclipse-based STS are completely free to use, while Intellij requires a separate license (but it is possible with a bit of inconvenience using the community version, and a 30-day trial version 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 hands-on experience is required, the final project deliverables will be shared, but we encourage you to write them yourself if possible.

Introducing the knowledge sharer ✒️

Hello. This is Everyone's Coding: Duding~

I am a lecturer who finds it very fun to explain useful knowledge in an easy-to-understand manner, and feels happy when students understand it. I have been working in lectures and development for over 20 years, and now I communicate through lectures, blogs, YouTube, etc.

I would be very proud if my small actions could reduce someone's suffering.
