@RestControllerでRESTAPI用のコントローラを定義する。
RestController (Spring Framework API) - Javadoc
Fedora41でVSCodeでやる。
まずSpring Boot Extension Packを入れる。
続いて、Spring Boot CLIを入れる。
まず、SDKMANを入れる。

Enjoy!!!
bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$ source "$HOME/.sdkman/bin/sdkman-init.sh"
bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$で、Spring Boot CLIのインストール。
bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$ sdk install springboot Downloading: springboot 3.5.5 In progress... ###################################################################################################################################################### 100.0% Installing: springboot 3.5.5 Done installing! Setting springboot 3.5.5 as default. bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$ spring --version Spring CLI v3.5.5 bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$
Installing: springboot 3.5.5って言ってるけど、Spring CLI v3.5.5らしい。
で、プロジェクト作成。
bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$ spring init --dependencies=web --build=maven --java-version=21 annotationRestController Using service at https://start.spring.io Project extracted to '/home/bg1/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController/annotationRestController' bg1@vbox:~/project/cloud/github.com/Sample/spring/annotationRestController/annotationRestController/src/annotationRestController$
で、できたのが、
こんな感じ。
手作業でいろいろ直す。
ソースのパスやファイル名など、
こんな感じに。
さらに、MainApplication.javaは、
こうする。
@RestControllerをMainApplicationクラスにつけて、コントローラのソースを分けずにhomeメソッドでコントローラを実装。
pom.xmlも、
こうする。

tomcat落としてからmvn spring-boot:runで実行。
うまくいけばこれが出る。
