Learn Java from Scratch - A Beginner's Guide - Step 08 - Understanding Spring Boot Magic - Embedded Servers

The video tutorial discusses the evolution of deploying Java applications, highlighting the complexity of traditional methods involving separate installations of Java and web servers like Tomcat, Weblogic, or Web Sphere. It introduces Spring Boot's embedded server concept, which simplifies deployment by packaging the server within the JAR file, requiring only Java to be installed. The tutorial demonstrates building and running a JAR file using Maven, addressing common issues like port conflicts. It concludes by exploring alternative embedded servers such as Jetty and Undertow, emphasizing the ease of using JAR files over WAR files.

What was the traditional process for deploying Java applications a few years ago?

• Install Java, then a web server, and finally deploy the application.

• Install a web server, then Java, and finally deploy the application.

• Install Java and deploy the application without a web server.

• Deploy the application directly without any installations.

How does Spring Boot simplify running Java applications?

• By requiring only a web server installation.

• By using embedded servers within the jar file.

• By using a different programming language.

• By eliminating the need for Java installation.

What is the first step in building a jar file using Maven?

• Run as Maven build and set the goal as install.

• Directly execute the jar file.

• Install a web server.

• Compile the Java code manually.

What command is used to run a jar file?

• java -jar

• mvn run

• mvn execute

• java -run

What is the main advantage of using jar files over war files?

• Jar files are larger in size.

• Jar files are easier to run.

• War files are more secure.

• War files require less configuration.

Which embedded server is included by default in Spring Boot?

• Tomcat

• GlassFish

• Jetty

• Undertow

What is the alternative to using Tomcat as an embedded server in Spring Boot?

• Spring Boot starter Jetty

• Spring Boot starter GlassFish

• Spring Boot starter Nginx

• Spring Boot starter Apache
