It explains the basic concepts step-by-step and helps you build practical knowledge by creating various applications that run in real-world web environments. By completing this course, you will be ready to be deployed immediately as a professional programmer.

Developing AI Applications with Spring Boot and Spring AI: Mastering OpenAI for Real-World Solutions

Beginners to Spring can quickly learn the entire Spring web application development process by creating examples.

We will learn how to create a system to support large amounts of data and traffic by creating it directly with Spring Boot.

In this course, you will learn how to develop a web application using various Java-based open source technologies including Spring, JPA, and Thymeleaf, which are actually operating services. If you study this course enough, you will be able to create your own web service or create a portfolio that will help you get a job.

This course uses Spring Boot and teaches you the core Spring technologies. Therefore, this is a useful Spring course for developers or students who are using Spring Boot-based projects.

Reactor, one of the core technologies of Spring WebFlux-based reactive applications, and Reactor Operator, which can be said to be the most important part of Reactor, if you want to make it yours, take the `Kevin's Easy-to-Understand Spring Reactive WebApplications: Reactor Part 2` lecture.

If you want to create a reactive application based on Spring WebFlux, take Kevin's easy-to-understand Spring Reactive WebApplications course. He will kindly guide you into the world of reactivity. ^^

This course is a course where you can learn the Spring Framework. Most courses only introduce the Spring MVC Project, so you will not be able to properly understand the terms, concepts, and operating principles, and you will learn without knowing how it works.

The best preparation course for those who are aiming for employment or a job change as a server developer. Gain hands-on project experience using Java and Spring and gain confidence in interviews.

Through training in thinking, expressing, and coding, you can easily understand and approach Java programming. You can understand the relationship between programming elements and gain confidence in future Java API utilization and projects through precise concept organization of object-oriented programming.

What if you need to study Spring Legacy projects? What if you want to create XML configurations one by one?

It's time to master Java's various features so you can apply them in practice! ^^ Let's make it completely yours by solving algorithm problems together. Teacher Eun-jong will continue to be with you in Part 2.

This lecture is an extension of the "Spring Boot Concepts and Utilization" lecture and covers the Spring Boot updates that have been made over the past two years. Check out the new features and changes from Spring Boot 2.1 to 2.4 and update to the latest version of Spring Boot.

Learn what problems can arise when implementing a first-come, first-served event system and how to solve them.

Learn what concurrency issues are and how to deal with them.

At some point in backend development, you start to have these concerns. It's that moment when services expand and traffic increases, and you begin to feel the limitations of simple REST communication and CRUD structures. I experienced these same issues in the field and went through much trial and error balancing performance and structural complexity. The solution I chose during that process was NATS. Its simple configuration based on a single binary, ultra-low latency performance in microseconds, and the fact that it provides essential features—from Pub/Sub to Queue Groups and JetStream—without being overkill made it a very practical choice for real-world service environments. This course is not just a list of NATS features. Based on the problems I faced in practice, I explain through code and workflows why I chose NATS in certain situations and how I designed the architecture. This course is designed to help everyone—from those new to messaging systems to backend developers preparing for employment and senior developers considering better architectures—understand distributed systems and grow to the next level.

Based on an understanding of Reflection and Annotations, it helps you clearly understand how the Spring framework operates!

Develop and deploy servers using Java, Spring Boot, JPA, MySQL, and AWS. While developing web applications, you will learn all the background knowledge, theories, and various technologies required for server development, as well as the meaning of various options, the history of Spring Boot, and the changes in the latest version.

Learn about Spring Data JPA, which provides several features to make using JPA (Java Persistence API) easier.
