🚩 This course is a roadmap course.
- This lecture is the first in a practical course in Java backend development. Please first check out the roadmap for mastering Spring Boot and JPA (link) .
Real-World Applications! Using Spring Boot and JPA
Spring Boot simplifies and eases the complex and complex Spring Framework. Adding the powerful ORM technology provided by JPA to this, it enables agile web application development while maintaining high productivity. For these reasons , leveraging Spring Boot and JPA for web application development is a global trend in the Java community.
Course Objectives
Even if you're familiar with Spring Boot and JPA, designing and developing web applications using these technologies in practice is a completely different matter. Typically, web applications go through the following development process.
General web application development process
- Requirements Analysis
- Domain and table design
- Architecture composition
- Develop core business logic
- Web tier development
- test
- Performance optimization
This course goes beyond simple examples like bulletin boards and uses challenging examples that replicate complex real-world scenarios. It covers the entire process, from requirements analysis to design, development, testing, and performance optimization. By designing and developing a web application from start to finish using these practical examples , you'll naturally learn the correct way to leverage Spring Boot and JPA. You'll also understand how to apply these technologies in practice. In particular, you'll learn and apply performance optimization techniques, which are crucial for practical use, step by step.
The entire course consists of two parts: Part 1, which covers designing and developing web applications, and Part 2, which covers developing APIs and optimizing performance. This lecture is the first of these two parts.
👨💻 Please note before taking the class!
- Part 2 API development and performance optimization is a separate lecture , and a link is provided in [Related Lectures] below.
Learning process
Part 1 - Web Application Development
Complex , practical examples, coded from start to finish!
Part 1 designs and develops a simple web application with member, product, and order domains.
The order of progression is as follows:
- Project Configuration: Create a project and configure the project environment so that Spring Boot, JPA, Thymeleaf view templates, Lombok, and the database work properly.
- Domain Analysis and Design: Analyze requirements and design the domain and tables. Once the domain and table design is complete, create entity classes using JPA and map them to tables.
- Domain Development: Develop core business logic for the Member, Product, and Order domains, and create test cases to verify them.
- Web Layer Development: Develop controllers and view templates (Thymeleaf) to enable the configured domain to operate in a web environment. You can check the actual screen in action.
Part 2 - API Development and Performance Optimization
These days, rather than using view templates to directly generate HTML on the server and respond, many developers are loading JSON data into APIs and returning it. The goal of this article is to understand the considerations and proper design guidelines for developing APIs using Spring Boot and JPA, and to complete the API with performance in mind.
Part 2 builds on the domain created in Part 1 to develop an externally usable REST API. We then step-by-step optimize the performance of the query API. This process provides a thorough understanding of JPA query tuning, a crucial practice.
- API Development Basics: Develop a basic REST API for registration, modification, and query.
- Advanced API Development: We'll explain the key considerations and design guidelines for developing query APIs using JPA in practice. We'll address JPA lazy loading issues and explain various performance optimizations step-by-step.
- Essential Optimizations for Practice: Covers practical issues that can lead to problems in practice if not handled carefully when using Spring Boot and JPA.
How to learn
This course is largely hands-on . Therefore, you'll get the most out of it by following the lecture from beginning to end, coding on your own .
Please note that this course does not cover Spring Boot or JPA in detail. The goal is to help those familiar with these technologies leverage them to their full potential, enabling them to develop effective web applications in the real world . Therefore, we recommend that you have a basic understanding of Spring and JPA before taking this course. However, even if you're not yet familiar with Spring or JPA, following along will give you a comprehensive understanding of how to develop and complete web applications in Java. You can also fill in any gaps in your foundational skills later on.

100% enrolledSpring Framework Mybatis 6개월 국비학원을 수료하고 Spring FrameBoot JPA 사용하는 회사에 입사하였습니다 처음에 구글로 CRUD를 검색해서 수박 겉햝기로 공부하였는데 엄청 헤매고 힘들었던 것 같습니다 그래서 만약 제가 이 인강을 먼저 알았더라면 정말 좋았겠구나 라고 생각이드네요 JPA를 입문하시는분들에게 이제까지 본 인강중에 최고인 것 같습니다 1. 내용이 알차다 2. 설명이 디테일하다. 이 인강 2번 더 돌려보고 소스파악되면 책구매해서 기초편도 겟할 예정 좋은 강의 올려주셔서 감사합니다
