在这篇文章中，我们将介绍如何设置 Spring Boot 项目。
Spring Boot 是用于构建 Web 应用程序和服务的流行框架。它建立在 Spring 框架之上，可以轻松创建独立的、生产级的基于 Spring 的应用程序。
在我们开始之前，您需要做一些事情才能跟进：
有几种不同的方法可以创建 Spring Boot 项目。在这篇文章中，我们将使用 Spring Initializr 来生成一个项目。
前往 Spring Initializr 网站并使用以下信息填写表格：
单击“生成项目”按钮，将下载一个 zip 文件。将 zip 文件的内容解压缩到您选择的目录中。
在文本编辑器或 IDE 中，将项目导入为 Maven 项目。如果您使用的是 Eclipse，则可以通过转到文件 -> 导入 -> 现有 Maven 项目来执行此操作。
现在项目已经设置好了，我们可以运行它了。
有几种不同的方法可以运行 Spring Boot 应用程序。最简单的方法是使用 Maven 插件：
mvn spring-boot:run
您应该看到类似于以下内容的输出：
