以下是创建简单Spring Boot项目的步骤。
Steps1: 打开Spring initializr https://start.spring.io 。
Steps2: 提供 组和 工件名称。我们提供了组名 com.w3codebox 和工件 spring-boot-example 。
Steps3: 现在，点击 Generate (生成)。
何时我们单击"生成"按钮，它将开始将项目打包为 .rar 文件并下载该项目。
Steps4: 提取 RAR File.
Steps5: 导入文件夹。
文件->导入->现有Maven项目->下一步->浏览->选择项目->完成
导入需要一些时间该项目。成功导入项目后，我们可以在 Package Explorer 中查看项目目录。下图显示了项目目录:
SpringBootExampleApplication .java
package com.w3codebox.springbootexample;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootExampleApplication
{
public static void main(String[] args)
{
SpringApplication.run(SpringBootExampleApplication.class, args);
}
}pom.xml
