Spring Tool Suite，STS 是一个 IDE（集成开发环境），非常适合开发 Spring Boot 应用程序。

下载并安装 STS

可以从 https://springframework.org.cn/tools 下载 STS。
选择操作系统（本例中为 Windows）。
下载 zip 文件并解压。
点击 SpringToolSuite4.exe 文件。
Spring Tool Suite 4 启动器对话框会询问工作区位置。输入位置，然后按“启动”按钮。

在 STS 中创建一个简单的 Spring Boot 应用程序

转到文件 -> 新建 Maven 项目。
点击下一步。将出现以下对话框
选择maven-archetype-quickstart
对于GroupId，输入com.tutorialspoint，对于ArtifactId，输入first-spring-boot-example。
点击完成。
完成后，将创建文件夹结构 -

打开pom.xml文件。在dependencies下添加以下内容。

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-autoconfigure</artifactId>
   <version>3.3.3</version>
</dependency>

此外，通过右键单击项目 -> 构建路径 -> 添加外部存档将 Spring 框架核心 jar 添加到构建路径

在 src/main/java 下创建一个新的 Java 类，包名为com.tutorialspoint.first_spring_boot_example。将类命名为FirstSpringBootTestClass。

FirstSpringBootTest.java

package com.tutorialspoint.first_spring_boot_example;

import org.springframework.boot.SpringApplication;    
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class FirstSpringBootTest {

   public static void main(String[] args) {   
      System.out.println("Hello World, this is First Spring Boot Test");
      SpringApplication.run(FirstSpringBootTest.class, args);
   }
}
