Java Spring boot 2.1.0版本获取404未找到错误

我一直在尝试在2.1.0版本中运行SpringBoot。即使在尝试访问localhost:8080时，我仍收到404错误。我已经修改了所有的控制器，服务在同一个主包，但没有运气。感谢您的帮助。下面是我的控制台日志。。甚至localhost:8080也无法工作

似乎Spring没有读取您的控制器，这似乎是一个结构问题。 请考虑下面的变化：

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>${spring-boot.version}</version>
    </dependency>

并且，主类必须位于根文件夹中。大概是这样的：

要使用rest端点，请尝试访问

localhost:8080/your_decise/mobilityCC

编辑：

确保您具有SpringWeb依赖项

org.springframework.boot
SpringBootStarterWeb
${spring boot.version}

控制器代码在哪里？如果没有路线，显然你会得到一个404找不到你有一些控制器/资源吗？如果你没有，显然，它不会显示任何东西。是的，我有一个控制器@restcontroller在使用componentscan的不同软件包中多次尝试后都不起作用。。然后放入主类包本身中。。。它不工作。你能提供更多的代码吗？你的文件结构也…运气不好。。。。这是我的包结构[link]H:\Desktop[/link]。。。还有一个问题，为什么localhost:8080也不工作？它也给出了相同的错误。2.1.0版本中没有设置默认的上下文路径，Tomcat在端口8080（http）上启动，上下文路径为“转到聊天室你能在GitHub上共享你的项目吗？谢谢@CristianoBombazar！你上次关于添加

springbootstarterweb

的评论帮了我的忙。

@RestController
@RequestMapping("/your_decide/")
public class MobilityApi {


    @Autowired
    private MobilityService mobilityService;

    @GetMapping("/mobilityCC")
    public Response retrieveOrderDetails(@RequestParam("orderid") String orderid) {
        return mobilityService.getOrderDetails(orderid);
    }
}

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>${spring-boot.version}</version>
