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.

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.

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:

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.

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.
