Spring Boot CLI - 默认语句
默认导入
Spring CLI 默认自动导入许多库,因此不需要显式导入。考虑以下常规脚本。
@RestController class FirstApplication { @RequestMapping("/") String welcome() { "Welcome to TutorialsPoint.Com" } }
这里导入@RestController,@RequestMapping注解已经被Spring Boot默认包含了。我们甚至不需要使用完全限定的名称。您可以通过运行应用程序进行检查。
输入以下命令
E:/Test/> spring run FirstApplication.groovy
您可以在控制台上看到以下输出。

自动主方法
我们不需要为 groovy 脚本创建标准 main 方法来初始化 Spring 应用程序。它是为 Spring Boot 应用程序自动创建的。
