Spring Boot参考指南-从app.groovy获取404示例

Question

我遵循了Spring Boot参考指南，得到了这个错误

HTTP Status [404] – [Not Found]
Type Status Report
Message /
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

这是密码

@RestController
class ThisWillActuallyRun {
    @RequestMapping("/")
    String home() {
        "Hello World!"
    }
}

spring run app.groovy
