启动jar时出现Spring引导错误404

Question

我正在尝试运行一个Spring Boot应用程序。我从教程中下载了一段代码，这样我就知道这段代码可以工作。当我运行我的jar文件时，它看起来就像我在8080端口上运行的应用程序，但我仍然得到404对于任何URL来说，我从来没有得到spring白色标签页面。我检查了8080端口上没有任何其他东西在运行，并且服务器已经启动并运行。

我不知道为什么我的申请没有反应。

package com.virtualpairprogrammers;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

    @RequestMapping("/hello")
    public String sayHello(){
        return "Hello";
    }
}

public static void main(String[] args) {
    SpringApplication.run(FleetmanApplication.class, args);

Answer 1

这样试试就行了：

@RestController
public class HelloController {

    @RequestMapping(path = "/hello", method = RequestMethod.GET)
    public String hello() {
        return "hello";
    }
}
