If I had to self-study Spring Batch using a book that easily exceeds 500 pages, I think I would have felt completely overwhelmed by the sheer volume. ㅜㅜ However, this course picks out only the core content necessary for actual application and helps you get a feel for the overall flow and practice of Batch in a short and impactful way over about 3 hours, which is just fantastic!! If you are curious about Batch, I highly recommend taking this course! haha

Overall, the structure was great, and I especially liked that there were many hands-on exercises. I was a "Spring Batch lecture nomad," but I am completely satisfied! The instructor's delivery was excellent, and they pinpointed the core concepts so well that it was easy to understand. I plan to keep reviewing and apply what I've learned to my actual work. I highly recommend this course to anyone studying Batch!

What you will gain after the course

  • From 'simple deletion' to 'bulk settlement', step-by-step practical code.

  • Selecting the 'optimal batch implementation method' for the situation

  • How to utilize 'Job Parameters' to respond to any environment

  • Flexible design of batch architecture (Job & Step)

🥵 You're saying... I'm the one in charge of Spring Batch...?

I am JSCODE Sini, who started as a developer and has produced over 200 developers while working as a bootcamp instructor for 5 years.

When I was a junior, I also suddenly became the person in charge of managing Spring Batch at my team leader's direction.
I had never even managed a batch before, and the code I opened looked like an alien language.
I remember being afraid to even go to work, worried that my lack of skills would be exposed. 🥶

With the pressure on, I spent the weekend searching for knowledge I could apply to my work immediately, but
the books on the market were so thick they were suffocating before I even opened them, and the lectures were well over 30 to 40 hours long.
I had to use it this coming Monday, so I felt completely lost, wondering, 'Do I really need to know all of this vast information?'


That's why I created this course so that those who are new to batch processing,
just like I was, can apply it to real-world tasks in a short period of time.


Practice makes perfect!
Rather than studying concepts for a hundred days,
it is fastest to implement even a small batch in code and apply it to a real-world project.



🎯 The goal of this lecture is clear.

The goal is for batch beginners to grasp the flow of batch processing in just 3 hours and become capable of reading and utilizing the
code.


I hope you don't have to tremble with fear like I did during my junior years.
Do you need to apply Batch to a project right away? Did you become a Batch manager starting today?


If so, I hope you can lower your fears through this course
and take away only the core concepts essential for real-world practice.
I'll see you in the course. ☺️



👍 Recommended for the following people!

I don't know anything about logs
Those who know how to develop,
but have no idea
how to use logs

I want to analyze and visualize logs!
Those who want to analyze logs
and use the ELK stack
to go all the way to visualization

I'm curious about monitoring.
Those who are struggling because they have
never done monitoring before
while studying development



🍀 What will you achieve after this course?

  • Understand the core flow and structure of Batch By understanding the overall mechanism of Spring Batch, you will experience being able to read batch code at a glance that once felt overwhelming.

  • Acquire essential concepts for immediate practical use Instead of getting lost in vast theories, you will master only the core concepts and operating principles that are essential in practice, such as Job, Step, and Chunk.

  • Customized Problem-Solving Skills for Real-World Scenarios By learning how the concepts you've acquired are applied to actual business logic in the field, you will be able to apply Batch to your own projects starting tomorrow.

  • Escaping the 'Talking Potato' status and gaining technical confidence You will gain the confidence of a practitioner who can proactively modify and operate code without panic, even when suddenly faced with batch management tasks.

What if you have questions while listening to the lecture?

If you have any questions or find something difficult to understand while listening to the lecture, please use the Question Board (Q&A Board) or the 1:1 Open KakaoTalk Room to ask!🤩

I will check and provide an answer as quickly as possible.



👩‍💻 There are many practitioners who write good code, but few educators who make code easy to understand.

A practitioner is someone who writes code well.


However, an educator is someone who contemplates day and night why the code was written that way and how to convey that code to students in the easiest possible way.


There are many experts in the field, but
when you actually listen to their explanations, they are often so difficult that you find yourself tilting your head in confusion.
This is because they focused more on listing knowledge rather than on the weight of education.


Receiving the wrong education makes the learning process itself painful,
and ultimately leads to unwanted results, wasting precious time and opportunities in your life.


I want to be more than just an 'instructor' who passes on skills;
I want to be a 'teacher' who contemplates your career and life together with you.

The power to turn complex concepts into our own language instead of jargon,
that is my pride as an educator.

Please take a look at the path I have walked and my sincerity,
and make a careful decision for your precious future.



💚 Introducing myself!

Hello! I am Sini from JSCODE.


It feels like only yesterday that I was dragged by a friend to attend a major class in college,
but I'm already approaching my 10th year since I started developing.


At first, I wanted to make a positive impact on the world through the programs I created.
However, as time passed, I came to one firm realization.


'Rather than creating services myself,
wouldn't properly raising one talented developer have a much greater impact on the world?'


If the developers I taught create wonderful services in their respective positions,
that positive influence will grow exponentially.


With that single mindset, I have trained over 200 developers at bootcamp sites over the past 5 years.
(* Produced successful candidates for LINE, Kakao, and Kurly)


Watching my students grow as they enter the industry,
I feel the power of education and a sense of pride every day.


Now, I intend to meet you in the wider online world, moving beyond the offline classroom.


I want to share the skills and know-how I have built up in the field without reservation,
helping you grow into a 'competent developer' who creates new value.


I sincerely hope that this lecture, prepared with great care,
brings a positive change to your life as a developer! 🙌

Who is this course right for?

  • A junior backend developer who "suddenly became the person in charge of batch processing starting today"

  • Practitioners who are "afraid of handling large-scale data"

  • Non-majors/beginners who "gave up while self-studying Spring Batch"

  • Job seekers "in need of a practical, industry-aligned portfolio"

Need to know before starting?

  • Basic Java knowledge

  • Spring Boot Basic Knowledge

  • It is helpful if you are familiar with MySQL and JPA, but even if you aren't, you won't have any major problems following along with the hands-on practice.

Hello! I'm Sini from JSCODE, who started as a developer and is now active as an educator.

I have personally built and operated critical national systems, but what I am actually best at is "explaining those difficult concepts so that anyone can understand them."

The actual field is naturally rough and complex. 🤯

But there's no reason the learning process has to be that way, right?

It doesn't matter what stack you want to learn right now.

I will break down the complex technologies of the actual field and feed them to you in a way that is very easy to understand! 🍀

Let's start the amazing experience of turning the complex ideas in your head into actual working services, easily and fun together with me!

    I love that instead of just saying "I used Batch!", you teach practical methods that actually appeal to companies! The explanations that allow you to grasp the architectural flow felt very beginner-friendly. When studying, I often use AI to resolve my questions, but I sometimes feel disappointed when the answers feel disconnected from real-world practice. I'm very satisfied that this lecture explains the parts one might naturally be curious about. I haven't watched the Jenkins section yet, but thank you for the great lecture...! Please make a follow-up course after the basics as well... haha.

      Hello Hyonattang! This is Sini from JSCODE!! I really hope you integrate the Jenkins part as well and make it all the way to the end of the course!! Haha. If you keep organizing the basics well, I will definitely make sure to greet you with an intermediate course when I have the time, just as you mentioned! Thank you so, so much for leaving such a lovely review! Haha.
