【SpringBoot项目报错】org.springframework.web.bind.MissingPathVariableException

报错一：

解决方法有两种：

二、@GetMapping(“/getInfo”) 改为@GetMapping(“/getIn/{id}”)

postman ->http://ip:port/xxxxx/getInfo/1

报错二：

org.springframework.web.bind.MissingServletRequestParameterException: Required request parameter ‘ids’ for method parameter type Long[] is not present

原因：@DeleteMapping("/delete")public BaseResponse delete(@RequestParam("ids") Long[] ids) {return xxx;}

解决方法：

@RequestParam 改为@PathVariable ，@DeleteMapping(“/delete”) 改为@DeleteMapping(“/delete/{ids}”)

postman ->http://ip:port/xxxxx/delete/122222,3333334

postman ->http://ip:port/xxxxx/delete/166666
