java - Spring Boot 引用指南 - 从 app.groovy 示例中获取 404

Question

我关注Spring Boot Reference Guide并收到此错误

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.

这是代码

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

我运行的命令。

spring run app.groovy

我得到的控制台日志。

我做错了什么吗？

Answer 1

我只是使用 sdkman 切换回 Spring CLI v1.5.3.RELEASE 就可以了。
