Study Notes

Spring Boot "Fat" JAR

A "fat" JAR includes both application code and all its dependencies, simplifying deployment.
It can be executed independently without requiring external libraries or server installations.

Spring MVC

Spring MVC supports a clear separation of concerns by organizing web applications into models, views, and controllers.
It provides built-in support for RESTful web services, allowing both JSON and XML data formats.

Component Scanning in Spring

Component scanning can be enabled by adding the @ComponentScan annotation on a configuration class.
Specifying the base package, such as com.mycomp.service, in the annotation directs Spring to scan for beans within that package.

Spring Boot and Spring MVC Application

A Spring Boot-based Spring MVC application can be easily configured using application properties, reducing boilerplate code.
It utilizes embedded servers, such as Tomcat or Jetty, enabling rapid development and deployment.
