Real-world! Spring Boot and JPA Utilization 1 - Web Application Development
With a practical example, we will design and develop a web application using Spring Boot and JPA. Through this process, you will understand how to use Spring Boot and JPA in practice.
This course is prepared for Basic Learners.
What you will learn!
You can develop Java web applications in practice using Spring Boot and JPA.
Understand the best way to leverage Spring Boot and JPA.
You can understand and design domain models.
Understand domain-driven design.
Spring Boot, if you want to use it well in practice?
Experience in-depth design and development.
🚩 This course is a roadmap course.
- This lecture is the first lecture that starts the practical course of Java backend development. Please check the Spring Boot and JPA practical complete conquest roadmap first. (Link)
Practice! Using Spring Boot and JPA
Spring Boot helps to make the complex and difficult Spring Framework simple and easy to use. Adding the powerful ORM technology provided by JPA to this, you can develop web applications agilely while maintaining high productivity. For these reasons , developing web applications using Spring Boot and JPA is a global trend in the Java camp.
Course Objectives
Even if you know Spring Boot and JPA, designing and developing web applications using these technologies in practice is a completely different matter. Web applications usually go through the following development process.
General web application development process
- Requirements Analysis
- Domain and table design
- Architecture composition
- Developing core business logic
- Web Layer Development
- test
- Performance Optimization
This course goes beyond simple examples like bulletin boards and uses difficult examples that can reproduce complex situations in practice. And it goes through all the processes in order, from requirements analysis to design, development, testing, and performance optimization. By designing and developing a web application from start to finish with such practical examples , you can naturally learn the correct way to use Spring Boot and JPA in this process. And you will understand how to use these technologies in practice. In particular, you can learn and apply performance optimization methods that are important in practice step by step.
The entire course consists of two parts: Part 1, designing and developing web applications, and Part 2, developing APIs and optimizing performance. This course is the first of the two.
👨💻 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 examples close to real-world practice , 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 Design: Analyze requirements and design domains and tables. Once domain and table design is complete, create entity classes using JPA and map entity classes and 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 operate the configured domain in a web environment. You can check the actual operating screen.
Part 2 - API Development and Performance Optimization
Recently, rather than using view templates to directly create HTML on the server and respond, it is common to load JSON data into an API and return it. The goal of this article is to understand the points to keep in mind and the correct design direction when developing an API using Spring Boot and JPA, and to complete the API while considering performance.
Part 2 develops a REST API that can be used externally based on the domain created in Part 1. And then, we step by step optimize the performance of the API for querying. Through this process, we will quickly and clearly explain the parts related to JPA query tuning that are essential in practice.
- API Development Basics: Develop a basic REST API for registration, modification, and inquiry.
- Advanced API Development: We will inform you of the precautions and correct design direction when developing APIs for querying with JPA in practice. We will solve JPA lazy loading issues and explain various performance optimization methods step by step.
- Essential Optimizations for Practice: Covers the things that can lead to practical problems if not used carefully when using Spring Boot and JPA.
How to learn
This course is mostly hands- on, so you'll get the most out of it if you follow the course from start to finish and code on your own .
Please note that this lecture does not explain Spring Boot or JPA in detail. The goal is to help those who have some knowledge of these technologies to make the most of them and create web applications in practice . Therefore, it is recommended that you take this lecture with a basic understanding of Spring or JPA. However, even if you do not know Spring or JPA well yet, if you follow along to the end, you will be able to get a general sense of how to develop and complete web applications in Java. After that, you can learn by filling in the basic technologies that you think you lack.

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

크! 모든것이 복선이라니 들켰네요 ㅋㅋㅋㅋㅋ 강의 준비를 할 때 사실 나름 치밀하게? 구성합니다. ㅋㅋㅋ 다른 강의들도 열심히 준비할게요. 고맙습니다. 2010psw님^^
