• java.lang.IllegalStateException: RequestParam.value() was empty on parameter 0


    今天使用feign进行远程调用,被调用方使用@RequestParam接受参数,但是在启动项目的时候报了错

    Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

    原因是使用@RequestParam接收参数的时候,需要参数名,如下(id)

    @RequestMapping("/selectSheetDetails")
        Map<String, Object> selectSheetDetails(@RequestParam("id") String id);
