Completed an in depth study of Spring Data JPA covering repository internals entity lifecycle, JPQL native queries, derived queries, sorting, pagination and performance optimization.
Built a Shopping Cart application using Spring Boot and Neon PostgreSQL implementing JPQL based queries, pagination with Pageable, and a clean layered architecture.

@its_shreeja21 https://t.co/VGkg5KiL3Q you can follow this alos

[Swadesh Chatterjee @Swadesh072]

No lectures are truly outdated if your goal is to understand Spring Boot deeply. You can skip some old configuration styles or deprecated APIs but do not skip the lectures explaining the internals JPA vs Hibernate vs JDBC the request lifecycle filters interceptors transactions and the IoC container Those concepts do not become outdated and are exactly what interviewers ask about.

Completed a deep dive into Hibernate internals, covering the Persistence Context, EntityManager, dirty checking, transactional write-behind, entity lifecycle, and how Transactional works behind the scenes.
Finally understand what actually happens from calling persist() to automatic SQL updates at commit instead of just using annotations.@CoderArmy @adityatandon02 @rohit_negi9

Best Spring Boot course. Nothing else comes close.

If you want to truly understand Spring Boot instead of just memorising annotations, this course is unmatched.

completed two spring boot persistence lectures covering spring jdbc jdbctemplate hikaricp hibernate, and jpa. built complete crud applications with mysql and learned entity mapping connection pooling embedded objects and how hibernate generates sql behind the scenes.@CoderArmy @adityatandon02 @rohit_negi9

Trying to build an AI interview platform. Here's the landing page, built with Claude Code. I'm more of a backend developer than a UI/UX designer, so I'd love to hear your feedback and suggestions on improving the design.@claudeai @ClaudeDevs

Today's learning Connected a Java application to PostgreSQL on Neon using JDBC and implemented basic CRUD operations (Create, Read, Update, Delete) It is a solid reminder that understanding JDBC fundamentals makes frameworks like Spring Boot much easier to grasp.@CoderArmy @rohit_negi9 @adityatandon02

Built a custom annotation with Spring AOP and went beyond the API to understand what actually happens internally. Learned how @-annotation binds annotation values, how proxies are created through BeanPostProcessor, and how the interceptor chain executes.
From custom annotations to proxy creation, method interception, and aspect ordering this is the internals that make Spring AOP work.@CoderArmy @rohit_negi9 @adityatandon02

learning spring aop part 3------>
Today i focused on pointcut expressions and finally started understanding how spring decides exactly where an advice should execute. instead of memorizing the syntax i learned how execution() within() args() this() target() @annotation wildcards and reusable @pointcuts work together along with the difference between jdk dynamic proxies and cglib proxies. following an excellent spring boot series and continuing to strengthen my backend fundamentals. thanks @rohit_negi9 @coderarmy and @adityatandon02 for the amazing content.

@iTanayVaswani It was never activism it was always selective activism everyone is entitled to their own opinion.

[Swadesh Chatterjee @Swadesh072]

Learning Spring AOP Part-2 from first principles and finally understanding why it exists not just how to use it. In this implementation, I learned how Spring creates proxies around target objects, wrote pointcut expressions, and implemented all five advice types: @Before, @After, @AfterReturning, @AfterThrowing, and @Around. I also explored JoinPoint, ProceedingJoinPoint, how proceed() works, modifying arguments and return values, handling exceptions, measuring execution time, and the complete advice execution flow behind the scenes.
Following an excellent Spring Boot series and gaining a much deeper understanding of backend architecture. Thanks, @rohit_negi9, @CoderArmy, and @adityatandon02, for the great content.

@ajay_2512x The website looks good but it would be even better if they added a demo video showing how to book a Tatkal ticket.

Learning Spring AOP from first principles understanding why it exists.
This lecture clearly explains cross-cutting concerns how AOP keeps business logic clean.
Following an excellent Spring Boot series and leveling up my backend architecture skills. #SpringBoot #Java #AOP #BackendDevelopment @rohit_negi9 @CoderArmy @adityatandon02

Learning Spring MVC Interceptors the request lifecycle, preHandle(), postHandle(), afterCompletion(), and how they work alongside Filters. Great explanation that made the concepts much clearer. Thanks for the awesome content! @CoderArmy @rohit_negi9 @adityatandon02

Spring Boot filters are far more than simple request logging. Learn how to inspect and modify requests responses safely, work with wrappers control filter order, and target specific endpoints.
Master OncePerRequestFilter ContentCachingResponseWrapper FilterRegistrationBean, and understand why request bodies can only be read once. Perfect for building production ready middleware.
