Spring Boot CLI Hello World示例 Spring Boot CLI环境设置 Spring Boot CLI “grab”依赖性扣除 在这个例子中，我们将创建一个基于Spring Boot + MVC + Rest的Web应用程序。 第1步：创建源文件夹 在E：\ Test文件夹中创建文件夹FirstApplication。 第2步：创建源文件 使用以下源代码在E：\ Test文件夹中创建FirstApplication.groovy文件 @RestController class FirstApplication { @RequestMapping("/") String welcome() { "Welcome to CodingDict.Com" } } 第3步：运行应用程序 输入以下命令 E:/Test/> spring run FirstApplication.groovy 现在，Spring Boot CLI将开始运行，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 Resolving dependencies.......................................................... ................................................................................ ........................ . ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _> | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v1.5.8.RELEASE) 2017-11-07 17:36:55.703 INFO 5528 --- [ runner-0] o.s.boot.SpringApplication: Starting application on ... 2017-11-07 17:36:55.707 INFO 5528 --- [ runner-0] o.s.boot.SpringApplication: No active profile set, falling back to default profiles: default 2017-11-07 17:36:56.067 INFO 5528 --- [ runner-0] ationConfigEmbeddedWebApplicationContext : Refreshing org.springframework.boot.context.embedded.AnnotationConfigEmbeddedWebApplicationContext@4c108392: startup date [Tue Nov 07 17:36: 56 IST 2017];
