Java Spring Framework, Spring Boot, Spring AI - Gen AI (Udemy.com)
Master Java, Spring and Spring Boot, Spring Security, Spring AI, Docker and Microservices with Telusko
Created by: Navin Reddy
Last updated April 2026
Our take
Based on the ratings of 45,758 students, a sample of their written reviews and the syllabus, as the course stood in April 2026. No course pays to be reviewed.
Navin Reddy's Telusko course is a long one: 55 hours and 500 lectures that begin with Core Java and only reach Spring around the eighteen hour mark, after Maven, JDBC and Hibernate. The syllabus then walks through Spring Boot, MVC, REST, Data JPA, AOP, Spring Security, JWT and OAuth2. It is built for people who want Java and Spring in one purchase, not for developers who already know Java and want to get straight to the framework.
The teaching is what students keep praising. Reviewers say he explains the why behind each step rather than just the how, and one experienced programmer says he comes back every few months to refresh concepts. Around 90 percent of 45,700 ratings are four or five stars. The complaints are specific. One three-star reviewer objects to him showing bad practices 'for test purposes' with no best-practice section to skip to. Others mention outdated lectures with no support reply, code piled into a single file, and time spent debugging his own mistakes on camera.
One caution on the title. The section list we have runs from Core Java to JWT and OAuth2, with no dedicated Spring AI, Docker or microservices section visible, so check the live curriculum if those are why you're buying. The course was refreshed in April 2026, though the outdated complaint arrived after that, from a student annoyed that a new version appeared days after purchase. For a Java newcomer who wants one long, patient path into Spring Boot, it's a solid pick. Developers who already know the language may prefer a course that skips the fourteen hour Java primer.
Pros
- Explains the reasoning behind each step; reviewers say they finally understand why, not just how.
- Starts with about 14 hours of Core and Advanced Java, so no prior programming is needed.
- Spring Security, JWT and OAuth2 get nearly 4 hours across three sections.
- Refreshed April 2026, with 39 quizzes and 13 coding exercises to practice on.
Cons
- Some lectures show shortcuts 'for test purposes' that reviewers say are bad practice for real work.
- Reviewers report outdated sections and unanswered support messages.
- No dedicated Spring AI, Docker or microservices section appears in the syllabus despite the title.
First time I really got to understand why we do any of the things in the first place instead of just going with the flow of "that is just how it is done".
Listed as All Levels, but the 14-hour Java primer means it's really aimed at beginners; experienced developers will skip a lot.
What you will learn
- Master Core Java and Object-Oriented Programming (OOP) concepts from scratch, building the perfect foundation for advanced framework development.

One of the best courses I have completed so far. As a software professional, the last framework I worked with extensively was Struts. Due to the nature of the tools and projects I was involved in over the years, there was a significant gap in my technical learning and hands-on development experience. This course has been exceptionally well designed. It starts with the fundamentals and builds knowledge step by step in a very structured and practical manner. The way concepts are introduced and progressively expanded makes learning both seamless and engaging. Rather than overwhelming learners with advanced topics from the beginning, it strengthens the foundation first and then gradually moves toward more complex concepts. What impressed me most is how the course takes a learner from the basics to an advanced level, providing the confidence and skills needed to work on and deliver complex real-world projects. The explanations are clear, the pace is appropriate, and the content is highly relevant to modern software development practices. I would highly recommend this course to anyone looking to refresh their technical skills, bridge a learning gap, or gain the expertise required to handle complex development projects with confidence.

Navin Reddy is a great instructor and teacher, his concepts are so clear and well articulated, I use his sessions to refresh my concepts every few months even though I'm an experienced programmer. His explanations are simple, clear and to the point helps you code better.

the course is generally great, i faced some issues related to the Udemy platform which is related to error of traffic of video and it asked to download the video. yes, please look after the health of website traffic.
By Shachi Chaware on 5/14/2026
whole course is absolutely good, but some of the videos are not starting specially from hibernate (one to many topic), please look into the issue. again thank you so much sir for this fantastic java springboot development course.
By Abdelrahman saad shaaban on 5/9/2026
a lot of content is outdated with no support and after i bought the course about couple of days they released a new one which is not acceptable and i sent a message with no reply. but to be honest he is a good instructor
By Ayush Mishra on 5/9/2026
if anyone is looking for a course of java which can be used for real world business spring boot applications this is it... the course covers everything we have used for our enterprise app... thanks a lot Navin for this..
By Dharmendra Kumar on 5/8/2026
This course exceeded my expectations in both content quality and practical learning experience. The concepts were explained clearly, the structure was well organized, and the hands-on examples helped me understand real-world applications effectively. I especially appreciated the balance between theory and practical implementation, which made learning engaging and valuable. The instructor’s teaching style was professional, easy to follow, and supportive throughout the course. Overall, this course was an excellent match for my learning goals and has significantly improved my knowledge and confidence in the subject. Thanks. @NavinReddy
By Adrian Bacsafra on 4/26/2026
I highly recommend this course. I took it as part of a re-skilling initiative to transition into Java, and it was a perfect fit for my learning style. The progression from core Java concepts to advanced application design was logical and challenging. The highly practical projects allowed me to build real-world confidence rapidly
By shrawan kolekar on 2/24/2026
Ngl, Navin Reddy is the absolute GOAT. Spring Boot used to have me totally cooked, but this course is a massive W. The way he breaks down Spring & Spring boot is just fire. Bro really understood the assignment, ate, and left zero crumbs. If you wanna secure the bag in Java backend, this is it, no cap.
By Sagarika Mahalik on 1/28/2026
Good, well-structured course with practical insights This course does a solid job of explaining the core concepts in a clear and organized way. The instructor explains topics well and includes practical examples that help reinforce learning. A few sections could be more in-depth or updated, but overall, it’s a valuable course and worth taking if you want a good understanding of the subject. I’d recommend it, especially for beginners or intermediate learners.
