Question

我一直试图在2.1.0版本中运行spring boot。即使尝试访问localhost：8080，我也收到404错误。我已经修改了所有控制器，并在同一主程序包中服务，但是没有运气。任何帮助表示赞赏。下面是我的控制台日志。即使localhost：8080也无法正常工作。

    </pre>

**Main class:**

@SpringBootApplication
public class DemoApplication {

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

控制器类：

    @RestController
    public class MobilityApi {


        @Autowired
        private MobilityService mobilityService;

        @RequestMapping(method=RequestMethod.GET,value="/mobilityCC")
        public Response retrieveOrderDetails(@QueryParam("orderid") String orderid) {
            return mobilityService.getOrderDetails(orderid);
        }

Answer 1

似乎Spring没有读取您的Controller，这似乎是一个结构问题。请考虑进行以下更改：

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


    @Autowired
    private MobilityService mobilityService;

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

并且，您的主类必须位于根文件夹中。像这样：

要消耗其余端点，请尝试访问localhost:8080/your_decide/mobilityCC

编辑：

确保您具有spring-web依赖项。

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