The core of the Spring framework,
Spring IoC

Most IT companies you know develop programs using Spring directly or their own frameworks modified from Spring. Furthermore, public systems operated by the government also use Spring-based e-government standard frameworks.

Without knowing Spring, you can't do Java-based projects or operate Java-based systems.

The Spring Framework consists of four modules that you will learn sequentially:

[1] Spring IoC (Inversion Of Control)

[2] Spring AOP (Aspect Oriented Programming)

[3] Spring MVC (ModelView Controller)

[4] Spring ORM (Object Relation Mapping)

The first of these, Spring IoC, is a core technology used to create business components that handle user requests in the backend , and it provides the core syntax of the Spring framework, including Spring AOP. Ultimately, Spring IoC is the core of Spring, and without understanding it, you can never truly understand Spring.

I recommend this to these people.

✅ Non-majors who dream of becoming Spring-based backend developers

The Spring Framework is not only conceptually challenging, but its content is also complex and extensive. Therefore, learning Spring is incredibly challenging for non-specialists. The terminology and explanations used by specialists are completely useless to non-specialists.

✅ New developers who need to use Spring right away

It's not easy for new developers to get involved in actual development, and even asking questions of other developers can be challenging. Even when they do ask questions, the answers they receive tend to be limited to formulaic coding patterns or API explanations, rather than concepts or principles. Understanding the concepts, principles, and terminology will help you adapt to the work more easily and quickly.

✅ New or experienced developers who need to operate Spring-based systems

When problems arise during operation, framework-based systems can be difficult to identify. This is because programs rely on the architecture and features provided by the framework. Therefore, understanding Spring's architecture is essential to troubleshooting operational issues.

Lecture Features ✨

Useless grammar and APIs are actually poison. Let's learn only what's necessary through selective focus .

Typically, when developing programs, we frequently use only about 10-20% of the APIs we use. For example, when developing a web application, HttpServletRequest provides around 40 methods, but we only actually use about 3-5 of them. So, why invest time and effort in learning syntax and methods we won't even use?

This course focuses on learning only the Spring IoC concepts and syntax used in actual projects, thereby increasing efficiency.

As you complete the project , you will learn the grammar and API .

The fragmented examples written while learning grammar and APIs are easily forgotten over time because they lack any connection to one another. Furthermore, it's difficult to understand how the APIs are applied in real-world projects, making the learning process incredibly frustrating. Therefore, while you may seem to have a general understanding of the material while listening to the lectures, when you try to build something yourself later, you'll find yourself at a loss as to where to begin.

This course focuses on practical application of grammar and APIs, rather than simply explaining general grammar and APIs. As you progress through the course, you'll naturally develop your own bulletin board program based on Spring IoC, and all the functions you develop are interconnected.

The best lecture tailored to the level of non-majors !

Programming skills are typically learned from senior developers or expert instructors who have previously studied the technology. However, these senior developers and expert instructors often use their own commonly used terminology and expressions when explaining, making it difficult for non-experts or beginners to understand.

This course explains Spring IoC from the perspective of a non-technical user, as closely as possible. The examples used in the practical exercises are also based on a bulletin board program that anyone can understand. I pride myself on incorporating my extensive experience in training non-technical students into professional developers into this course.
