Advanced Java + Spring Boot Bootcamp (9 Weeks)

Welcome to the Online Spring Boot + Advanced Java Bootcamp repository!

This repo contains all course materials, organized into daily directories (Week-01 through Week-10). Each Week builds on the previous one to create a Recipe API project that you’ll polish into a portfolio-ready capstone by the end of the program.

How to Use This Repo

1. Structure

Each Week has its own folder:

• Week-01-Spring-Core/
• Week-02-Spring-Data/
• Week-03-Web-Services/
• Week-04-Spring-Web/
• Week-05-Spring-MVC/
• Week-06-Consuming-APIs/
• Week-07-Testing-AOP/
• Week-08-Security/
• Week-09-Deployment/
• Week-10-Capstone/

Inside each daily folder, you’ll find:

• 1_lecture-notes.md → comprehensive explanation of the Week’s topics, with working code samples.
• 2_quiz.md → 5-question quiz with answers.
• 3_resources.md → links to CodingNomads course lessons, the labs repo, and official docs.
• 4_assignments.md → 3–5 coding challenges to reinforce the concepts.
• Demo → the demo project used during the lecture. (to run, open them as a separate project)

2. Running the Project

• Each Week builds on the Recipe API project.
• Start with Week 1 to set up the Spring Boot project (Gradle + Java 17).
• Update your code daily using the lecture notes and assignments.
• By Week 10, you’ll have a feature-rich, secure, cloud-deployed application.

3. Requirements

• Java 17
• Gradle (wrapper included via ./gradlew)
• MySQL (local or AWS RDS instance)
• Recommended IDE: IntelliJ IDEA or Eclipse
• Tools: Postman or cURL for API testing

Daily Overview

Week 1 – Spring Core

• IoC, Dependency Injection, Beans, Component Scanning
• Setup Gradle Spring Boot project
• Outcome: Understand DI and bootstrap Recipe API project

Week 2 – Spring Data (JPA & Repositories)

• Entities, relationships, JPA repositories
• Configure MySQL database
• Outcome: Persist and query recipes in DB

Week 3 – Web Services (REST APIs)

• REST principles, HTTP methods, controllers
• Implement CRUD API for recipes/ingredients
• Outcome: Expose Recipe API endpoints

Week 4 – Spring Web

• @Controller vs @RestController
• ResponseEntity and custom error handling
• Global exception handling with @ControllerAdvice
• Outcome: Robust API with proper responses

Week 5 – Spring MVC & Thymeleaf

• MVC pattern (Model, View, Controller)
• Thymeleaf templates, form binding, @ModelAttribute
• Outcome: Add web UI for Recipe API

Week 6 – Consuming APIs

• RestTemplate & WebClient
• Integrating external APIs (e.g., jokes, nutrition info)
• Outcome: Extend Recipe API with 3rd party data

Week 7 – Testing & AOP

• Unit + integration tests with JUnit, Mockito, MockMvc
• AOP basics (logging, performance monitoring)
• Outcome: Build test coverage and logging aspects

Week 8 – Spring Security

• Authentication vs Authorization
• In-memory users, PasswordEncoder, role-based access
• JWT/session-based authentication
• Outcome: Secure Recipe API with login + protected routes

Week 9 – Deployment (AWS)

• Package Spring Boot app (bootJar)
• Deploy to AWS Elastic Beanstalk + RDS
• Configure env variables and autoscaling
• Outcome: Live cloud deployment of Recipe API

Week 10 – Capstone

• Final polish of Recipe API
• Tests, documentation, AWS deployment link
• README & portfolio preparation
• Outcome: Portfolio-ready backend project

Helpful Tips

• Build incrementally: Don’t skip weeks — each builds on previous work.
• Assignments first: Try challenges before looking at solutions.
• Check tests: Run ./gradlew test often to validate your progress.
• Use resources: CodingNomads lessons + labs repo are linked daily.
• Ask questions: Pair with mentors or peers if you get stuck.
