[Java Advanced Practical Project] Spring Core + H2 Based Food Truck Kiosk System Development

[Java Advanced Practical Project] Spring Core + H2 Based Food Truck Kiosk System Development

"Build practical implementation skills with an order system project using Java and Spring Core!"

This course is a hands-on project course where you'll directly implement a console-based food truck kiosk application.
It's prepared for beginners with Java fundamentals or those who have studied Spring a bit but lack confidence in implementing actual applications.
Building on the foundational project experience from Part 1, this time you'll use Spring Core, JdbcClient, and H2 database to implement a more complex ordering system step by step.

• Project-Based Hands-On Practice:
  Rather than simple follow-along exercises, this is a hands-on practice-centered structure where students first think through and implement solutions based on given requirements.

• Pre-learning → Direct Implementation → Implementation Explanation approach:
  When specific technologies are needed in the course, we first cover the concepts in separate lessons,
  then students implement first, followed by comparative learning with the instructor's code version and explanations.

• Practice-Oriented Design:
  Structured to provide experience through the entire process from requirements analysis to structuring, implementation, and testing, following real-world workflows.

• Gaining experience in implementing domain-driven applications that enhance thinking skills using Java + Spring Core

• Gaining practical backend skills through improved implementation/design abilities

• Strengthening foundational skills for web application development

• Not just simple grammar, but gaining confidence that you can create actual programs

• Java 17+

• Spring Framework Core

• Spring JdbcClient

• H2 In-Memory Database

• JUnit Testing Framework

• Domain-Driven Design (DDD) Based Design

• Layered Architecture Structure

• Those who know Java syntax but lack confidence in implementing real-world projects

• Those who have learned Spring Core but lack experience in direct application

• People who want to create actual working console-based applications

• Those who want to build a solid foundation as a Java backend developer

• Those who have taken Part 1 lectures and want to implement more complex systems

This course is prepared to move beyond simply 'following along with code' and provide you with the experience of completing your own application by directly designing and implementing an application.

No matter how good a technology is, if I can't think about it myself and utilize it, I think it's like 'watching a spectacular fireworks display in a daze, unable to express that moving feeling outwardly'.

Rather than just staring at code, I'll help you all the way so that this can be your first step toward becoming 'someone who can write code on their own' in real-world situations.

Don't give up on your dream of becoming a Java developer, and I hope you'll do your best until the end to successfully enter the field as a developer!

Q. I haven't taken the Part 1 course - is it okay to just take this course?

It's possible.

However, since this course includes more complex structures and technologies than Part 1,
if you don't have experience with basic console application implementation flow and requirements analysis, we recommend taking Part 1 first before proceeding.

Q. I'm hearing about JdbcClient for the first time - isn't it difficult?
JdbcClient is a newly introduced feature from Spring 6.1, and it's more concise and intuitive than the existing JdbcTemplate.

Since the course explains the usage step by step, you don't need to worry about it.

Q. Isn't a console project too simple?
Beyond simple CRUD operations, you can experience order status management, user/admin role separation, statistics features, and other
structures and designs that can be directly applied to actual web-based systems.

As you'll see when you implement it, it's not as simple as you might think.

Q. Can I use this project as a portfolio?
Of course.

The order-related domain is a commonly seen domain in web-based services, so I think understanding this domain is important.

The fact that you can implement a console-based ordering system with an inconvenient UI, when thought about in reverse, can give the impression that "you've studied properly to master Java fundamentals", so I think it can make for a good portfolio.
