Master Java Backend Development with Spring & Spring Boot — From Foundations to Production

This is not just another Spring Boot course — it’s a complete backend engineering journey designed to help you think, design, and build applications like a real Java Backend Engineer.

You will start from Spring Core fundamentals and gradually build a production-ready backend featuring REST APIs, database integrations, security, performance optimization, caching, transactions, observability, and cloud deployment.

Every concept is explained with real-world reasoning — not just syntax.

What You Will Learn — Section by Section

Section 1 — Spring Core & Maven: The Fast-Track Foundation

Start with the backbone of Spring development:

• Why Core Java alone is not enough for modern backend apps

• Maven fundamentals and dependency management

• IoC, Dependency Injection, Beans & ApplicationContext

• Creating beans using @Bean and @Configuration

You’ll understand how Spring really works internally.

Section 2 — Spring Beans Deep Dive

Move beyond basics into advanced bean management:

• Autowiring strategies, @Primary, @Qualifier

• Bean scopes (Singleton, Prototype)

• Lifecycle hooks with @PostConstruct & @PreDestroy

• Constructor vs Setter vs Field injection

• Programmatic bean registration

Learn to solve real problems like NoUniqueBeanDefinitionException.

Section 3 — Mastering Spring Boot REST API Development

Build professional REST APIs:

• @RestController, @SpringBootApplication, Auto-Configuration

• Request handling (@PathVariable, @RequestBody, Headers, Params)

• API Versioning strategies

• RequestEntity & ResponseEntity

• HTTP fundamentals & best practices

You’ll build APIs like production systems.

Section 4 — Spring Boot Essentials

Improve project structure and developer experience:
