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: Clean package architecture Spring Boot DevTools H2 Database setup & data loading Better logging & development workflow Section 5 — Spring Data JPA Learn database interaction the modern way: ORM fundamentals Entities, Repositories & DTO pattern Lombok usage Derived queries & data mapping CORS handling Stop writing boilerplate SQL. Section 6 — Databases with Docker Move from local DB to containerized environments: Docker fundamentals for backend developers Running MySQL with Docker Docker Compose with Spring Boot Persistent volumes & configuration Section 7 — Building Real Backend Features Hands-on feature development: Contact API implementation Hibernate schema generation End-to-end API testing with UI Section 8 — Essential Backend Skills Learn production-ready practices: Global exception handling Backend validations JPA Auditing OpenAPI / Swagger documentation Web scopes (Request, Session, Application) Section 9 — Mastering JPA Relationships Deep dive into entity mappings: OneToMany & ManyToOne relationships Fetch vs Cascade explained clearly Deletion strategies Real-world relationship modelling Section 10 — Spring Security Essentials Understand how Spring Security behaves internally: Default security behavior Custom configurations CORS setup Internal authentication flow explained Section 11 — Authentication: From Passwords to JWT Modern backend authentication: Hashing vs Encryption vs Encoding Password encoders JWT token generation & validation Custom filters for authentication flow Section 12 — Database Authentication & CSRF Protection Build secure real-world login systems: Users & Roles design Custom AuthenticationProvider Derived queries for validation CSRF attack theory & implementation Section 13 — Logging in Spring Boot Design production-grade logging: Logback configuration Structured logging strategies Debugging and monitoring techniques Section 14 — Aspect-Oriented Programming (AOP) Handle cross-cutting concerns: Aspect, Advice & Pointcuts @Around, @Before, @AfterReturning, @AfterThrowing Performance logging and centralized exception handling Section 15 — Advanced Queries in Spring Data JPA Improve database performance: JPQL & Native Queries Named Queries Solving N+1 problems Batch fetching strategies Section 16 — Authorization, Sorting & Pagination Enhance API security & data handling: Roles vs Authorities Securing APIs Sorting & Pagination implementation Section 17 — Mastering Transactions Understand real transaction behavior: @Transactional internals Propagation & Isolation levels Rollback rules Production pitfalls Section 18 — Spring Cache & Performance Optimization Make APIs faster: @Cacheable, @CachePut, @CacheEvict TTL-based caching Caffeine integration Section 19 — Real Feature Development Build advanced backend workflows: User profile management Resume uploads Job bookmarking & application APIs ManyToMany best practices Section 20 — Configuration & Profiles Master environment-based backend setups: @ConfigurationProperties Externalized configuration Profiles for DEV/QA/PROD Conditional bean creation Section 21 — Production-Ready Observability Monitor backend systems like industry experts: Spring Boot Actuator Metrics, logs & tracing OpenTelemetry & Micrometer Section 22 — Consuming REST APIs Learn how backend services communicate: RestClient usage HTTP Service Client Service grouping strategies Section 23 — Deploying to AWS Take your backend to the cloud: AWS RDS setup Elastic Beanstalk deployment Production configuration
