在IntelliJ IDEA Community建立Spring Boot專案的方式如下。
範例環境：
- Windows 64 Bit
- Java 11
- IntelliJ IDEA version:2019.2.3 (Community Edition)
到Spring Initializr產生Spring Boot專案的基本目錄及設定zip檔。
選擇[Maven Project]， Language選[Java]，Spring Boot版本選擇穩定的2.1.9。
設定Maven專案名稱，可任意命名。
這裡[Group]命名為com.abc；
[Artifact]命名為spring-boot-demo
[Packaging]選擇[Jar]；
[Java]選擇[11]。
在搜尋欄輸入Web，點選Spring Web加入為依賴。
最後點選[Generate]，則Spring Initializr會根據以上設定產生下載的zip檔。
把下載的zip檔案移到想擺放的目錄位置並解壓縮。本範例放在D:\MyProject\IdeaProjects
開啟Intellij IDEA，選擇[Import Project]。
找到剛解壓縮目錄中的pom.xml，選擇後按OK。
以下皆維持預設，直按Next。

如果是第一次匯入因為IntelliJ IDEA需要載入一些maven相關的檔案，所以會比較慢。
匯入後的Spring Boot專案目錄結構如下。
Spring Intitializr生成的Spring Boot Web專案的pom.xml。
pom.xml
<?xml version="1.0" encoding="UTF-8"?>

Spring Intitializr生成的Spring Boot Web專案的進入點SpringBootWebApplication類別。
SpringBootDemoApplication
package com.abc.springbootdemo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootDemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootDemoApplication.class, args);
}
}
在SpringBootDemoApplication上按滑鼠右鍵，點選[Run 'SpringBootDemo....main()']啟動專案。
啟動成功會在IntelliJ IDEA下方的Run視窗印出下面訊息。
