Exercise 3: File Transfer Application
Build a file transfer server and client that can reliably transfer files over TCP, handling large files and showing progress.

Lire l'article →Spring Boot Code Examples
Working code for the Spring Boot Teaching Materials.
Lire l'article →Spring Boot Advanced Code
Corresponds to Modules 9–12 (Testing, Actuator, Production Deployment, Microservices patterns).
Lire l'article →Spring Boot Beginner Code
Corresponds to Modules 1–4 (What is Spring Boot, Setup, First Application, Core Concepts).
Lire l'article →Spring Boot Intermediate Code
Corresponds to Modules 5–8 (REST APIs, Spring Data JPA, Spring Security, Configuration).
Lire l'article →Module 1: What is Spring Boot?
Summary: Spring Boot is not a replacement for Spring; it is a way to use Spring with less configuration and faster development.
Lire l'article →Module 2: Environment Setup
Option A: Eclipse Temurin (recommended): Download: adoptium.net Choose JDK 17 or 21 LTS
Lire l'article →Module 3: Your First Application
After generating from Spring Initializr you typically have: src/main/java — application code src/main/resources — config, static files, templates src/test/java — tests
Lire l'article →Module 4: Core Concepts — IoC, DI, and Auto-Configuration
Your code creates and configures dependencies
Lire l'article →Module 5: Building REST APIs
REST conventions: Use nouns for resources (e.g. /users, /orders), HTTP methods for actions.
Lire l'article →Module 6: Spring Data JPA
Add to pom.xml (Maven) or build.gradle (Gradle)
Lire l'article →Module 7: Spring Security
Once added, every request is secured: default login form, default user, and all endpoints require authentication unless configured otherwise.
Lire l'article →Module 8: Configuration & Profiles
Both live in src/main/resources. Spring Boot loads them automatically.
Lire l'article →Module 9: Testing
Spring Boot starters include JUnit 5 and Mockito. For MockMvc you need spring-boot-starter-web (and usually spring-boot-starter-test, which brings AssertJ, Hamcrest, Mockito, and JSON path).
Lire l'article →Module 10: Actuator & Monitoring
By default, only /actuator/health is exposed over HTTP (and often only a simple status). You configure which endpoints are exposed and whether they show details.
Lire l'article →Module 11: Production Deployment
Spring Boot packages the application and embedded server into a single “fat” JAR.
