  • 关于客户端向服务端发送请求显示404问题

    先给我出有问题的控制层代码

    @RequestMapping("weatherInfo")
    @Controller
    public class WeatherInfoController {
    
        @Autowired
        private WeatherInfoService weatherInfoService;
        /**
         * @description 通过城市编号获取天气数据
         * @param cityId
         * @return
         */
        @ResponseBody
        @RequestMapping("/getWeatherDataByCityId")
        public WeatherReponse getWeatherDataByCityId(@PathVariable("cityId")String cityId){
            WeatherReponse resp = weatherInfoService.getWeatherDataByCityId(cityId);
            return resp;
        }
    }

    返回404错误 为什么请求失败了那?

    请求路径:http://localhost:8099/weatherInfo/getWeatherDataByCityId/101010100

    查看请求路径并没有问题,是什么原因导致的那?

    @PathVariable属性是从uri请求路径中读取参数它的使用要在@RequestMapping("/getWeatherDataByCityId/{cityId}")中采用{cityId}来占位接收参数

    我忘记写{cityId}所以导致出现请求无法成功
