Course Description

Spring Boot is the best Java framework for developing web applications. It favors convention over configuration, making it super easy to develop stand-alone, production-grade web services and APIs.

Become a Java Web Developer and Build Powerful APIs!

The Spring Boot Development Bootcamp offers support for Visual Studio Code and IntelliJ. The curriculum is as follows:

  1. Setting up a Spring Boot Project: Create a Spring Boot Project using best practices.

  2. Model View Controller: Build a Web application that adheres to the Model View Controller design.

  3. Field Validation: Validate fields prior to form submission to prevent the storage of invalid data.

  4. Three-Layer Codebase: Refactor your code to make sure it's clean and scalable.

  5. Bean and Dependency Injection: Loosely couple your code using beans.

  6. Testing a Spring Boot Web Application: Write unit and integration tests to verify that your application is behaving correctly.

  7. React: Connect your Spring Boot application to a React Front-end.

  8. REST API: Develop a REST API that can process GET / POST / PUT / DELETE operations.

  9. OpenAPI: Document your application using the OpenAPI specification.

  10. Exception Handling: Make your API resilient by throwing and handling unchecked exceptions inside @ControllerAdvice.

  11. Spring Data JPA (SQL): Develop a REST API that interacts with an SQL database. Define relational tables that contain @OneToMany and @ManyToMany relationships.

  12. Spring Boot Security: Secure your application through Basic as well as Token-based Authentication (JWT).

This is the most interactive web development course online. Every section is packed with coding exercises.

We're excited to have you on board. See you in class!

If you're seeking a course that guides you step-by-step toward becoming an intermediate-level learner with confidence in what you've mastered, look no further. The instructor excels at breaking down complex topics into easily digestible explanations, making it accessible to almost everyone. What I particularly appreciate about Rayan's courses is that he not only teaches how to build programs but also explores debugging. This allows you to understand how your programs operate under the hood, fostering a deeper comprehension of their functionality. Thank you for being such a great instructor! Even though some of the content is a bit outdated, I was able to follow along with the course and workbook without encountering any major issues. (19/12/2024)

This is the "BEST" Spring Boot Course that I found on Udemy. It starts from scratch to teach you how to develop a RESTful API and connect the server to the database. The content includes Postman testing, Spring Boot testing (Mockito and MockMVC), ORM, and Spring Security (really worthy: Spring Security lecture). The content is based on very recent material compared to other courses that you can find on Udemy. It is worth buying this course and supporting such great teachers, so that they can continue to produce high-quality lectures for us learners. Thank you, Rayan Slim, Jose Portilla, and Jad Slim!

I could understand what you were trying to do with thymeleaf but I feel you should just use react or angular from the beginning, it felt like a waste of time, I say that because I put in time, thought and effort into something that I would never use and since I never used it before I put extra effort to learn it. Also I feel once you got to mod 2 we should have started with a project from the ground up to really get the feel of building an app not just fixing what was already built. Sure we can go back and build it ourselves but if we run into issues there is no one live to ask. We are not professionals yet going on the web can help but have to know what we are looking for. Seeing different solutions written in different ways and not knowing which way or how to implement it can get overwhelming. Trying ourselves then watching the solution or getting help watching it goes a long way with someone who is new to this. Great job though I will look to your courses first when I need to learn more.

After having taken this course, I can say with confidence that it is one of the best courses I have taken on this platform. Rayan is gifted with the ability to explain concepts in a very clear and simple manner, and this is a talent that only few people can boast, especially here in Udemy. In addition, the workbooks and exercises make it easy to remember concepts, because practice is what matters in programming. On the other hand, I would have liked the course not to have dedicated so much time to Thymeleaf, which is a technology that is practically not used at the business level, and it would have been better to cover topics that are more important, such as the interaction of Spring Boot with databases.

"Every once in a while, you come across THAT course on a subject that truly stands out. This is that course for Spring Boot. With an incredibly vast topic like Spring Boot, finding the right balance between pace, delivery method, and content can be challenging, but this course has struck the perfect balance to get you started. The pace was great, and the diagrams added clarity to complex topics. A big shoutout to Rayan and the entire team for crafting such a phenomenal course!"

By Maryam Alsulaiman on 7/10/2023

Everything in this course is amazing! The presentation and the content are well-organized. Every section has workbook exercises, challenges, and a cheat sheet :) I really enjoyed this course and got the benefits. Thank you Rayan, you are such a great instructor. I was just hoping that the Spring Security section would cover roles and authorities since they are extremely important in the security field.

By Anonymized User on 2/13/2023

This course was excellent in helping me understand Spring Boot. Before, I was pretty weak in my knowledge of the framework but now I feel confident enough to start working on my own projects to further my learning and understanding. I also appreciate the cheat sheets at the end of each module and the workbooks to help me practice. However, I do think there was too much time spent on thymeleaf since it's not really used anymore. It was also getting harder to follow along especially in the JWT section since I couldn't see all the files on the editor. There were a couple of times I ended up following an example when it ended up getting deleted (like creating the filters), so I wish you can mention or maybe add a small note on the screen to just watch. Overall, it was a good course and I definitely learned a lot. Thank you!

By Daniel Klahre on 1/31/2023

When I first rated this I gave a 3 because the beginning was full of abstract text book descriptions. But once the course started getting hands on I noticed some real progress. It's obvious that Rayan does Java for a living. One disappointment is that I usually wait 3 to 4 days for answers to my questions on the course discord channel. My last question hasn't been answered for 10 days. This has really set me back but at least the course material is solid.

By Nguyen Ngoc Thien FX10909 on 7/27/2022

Crazy, crazy, crazy good course I gotta say. Thank you Ryan and the team for creating this wonderful course. I knew Spring Boot before but still learned a lot in this course, especially in the JWT/Security section. The breakpoints really help me understand what's going on under the hood. The workbooks is great also, it helps me practice what I learned One side note though, the instructor sometimes used advanced English words that I've never heard before, so I had to pause the video and checked that word, but that just a minor thing Overall: 5 star and highly recommended

By 曾理(Steven) Zeng on 7/4/2022

I follow closely when Rayan is designing this course, come back whenever a new chapter is released. I really love Rayan's course, If he teaches any other techs in the future, I'm willing to take it. Hopefully he teaches Spring microservice in the future. I don't really know what it is, but I've seen other students talked about it many times in Discord Channel, it seems we can gain a lot of flexibility with it!
