Step01.md

What You Will Learn during this Step:

• Set up an Maven Project with Eclipse.
• Intellij Link : https://www.jetbrains.com/help/idea/2016.2/getting-started-with-maven.html#create_maven_project
• Copy Two Files pom.xml and Application.java
• Launch Your First Spring Boot Application.
• You will be introduced to Maven
  • Dependency Management

Cool thing to note!

• Without a lot of configuration, we are up and running with a web application
• Refer https://github.com/in28minutes/SpringMvcStepByStep/blob/master/Step15.md to understand the sort of stuff - web.xml, dispatcher servlet configuration, maven dependency management and plugins - that are need to launch a typical web application without Spring Boot!

What You Will NOT Learn during this Step:

• Spring Boot does a lot of magic. This magic is called Auto Configuration. We will discuss about different terms related to Spring Boot - Starter Parent, Starter projects, Auto configuration - in depth during our first 10 steps.
• As far as this step is concerned, we will focus on getting up and running with Spring Boot. We will understand all the magic a little later.
• We will copy a lot of code in this step - just to avoid typos

Exercises

• If you are comfortable with Spring, try to create a few dependencies and see if are automatically auto-wired!
