All language subtitles for 009 Component Scanning - Coding - Part 1_en

Instructor: All righty, let's go ahead and move in here

and take care of our normal housekeeping,

stopping all apps and closing all windows.

And I'll move into my finder window here,

and I'll move into our dev-spring-boot directory

and our 02-spring-boot-spring-core.

And for this constructor-injection,

I'll simply copy and paste this directory,

and then I'll rename it as 02-component-scanning.

And now I'll simply open this directory here in IntelliJ.

So lemme just move in here to my code,

and I'm gonna create a new package.

And I'll give the package name of rest.

And I'll also create another new package.

And I'll call this common.

And then I'll move my DemoController into my package rest.

Alrighty, so that looks good.

And then I'll also move my Coach and CricketCoach

into the common package.

And then note here, these are all sub packages

of our main springcoredemo application.

So they'll be component scanned automatically for us

using the default component scanning of Spring Boot.

Let's go ahead and run this application.

And, hmm, that's weird,

this error, parse ConfigurationClassParser.

Okay, great.

So I can resolve this by simply doing a rebuild

on the project because I had some old compiled code

from one of the previous projects.

Now let's go ahead and swing over to our web browser

and open up our endpoint localhost:8080/dailyworkout.

And everything loads up for us a-ok.

So our app works because we simply

just moved those sub packages

of our main Spring Boot application.

So this is pretty good.

We're making use

of the default component scanning of Spring Boot.
