Springbootcli 简明教程
Spring Boot CLI - Hello World Example
在此示例中,我们将创建一个基于 Spring Boot + MVC + Rest 的 Web 应用程序。
Step 2: Create Source File
在 E:\Test 文件夹中使用以下源代码创建 FirstApplication.groovy 文件。
@RestController
class FirstApplication {
@RequestMapping("/")
String welcome() {
"Welcome to TutorialsPoint.Com"
}
}
Step 3: Run the application
键入以下命令
E:/Test/> spring run FirstApplication.groovy
现在 Spring Boot CLI 将发挥作用,下载所需的依赖项,运行嵌入式 Tomcat,部署应用程序并启动它。您可以在控制台上看到以下输出。
E:\Test>spring run FirstApplication.groovy
