Introduction to Spring Boot

Creating a Spring Boot Project with Maven

• Group Id: Identifies the organization (ex: com.ltp)
• Artifact Id: Determines the name of the application (ex: hello-spring)
• Dependency: Software that your application depends on.

Maven Standard Directory Layout:

• src/main/java: source code.
• src/main/resources
  • static: images, CSS, static HTML.
  • templates: dynamic HTML templates.
  • application.properties: application properties and settings.
• src/test/java: application tests.

Compiling and Running

• mvnw spring-boot:run: compiles and runs your application.
• mvnw clean spring-boot:run: cleans target folder, compiles, and runs your application.
• mvnw package: builds and packages the compiled classes into a JAR file.
• java -jar: runs the JAR file.

Client-Server Model

1. Client: Entity making a request.
2. Server: Machine receiving the request.
3. IP address: Sequence of numbers that identifies a server.
4. Port: Tells the server where to forward the request.
