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.

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.

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:

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.

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.
