Spring boot - Rest Service - 获取随机HTTP状态400

Question

我找不到原因为什么......但我随机获得了Http 400，param not present：

Required String parameter 'id' is not present. 

我在Postman和不同的Rest Client中得到这个，

这是我的代码：

 @RequestMapping(path = "/borrower", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
   @CrossOrigin(origins = "*")
    public ResponseEntity<?> borrower(@RequestParam(value = "id") String cuit, @RequestHeader("Authorization") String token)  throws Exception {

           // some business code
       return ResponseEntity.ok().build();
    }

我使用的是Spring boot 2.0.1

如果你这样试试怎么办？

    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
public ResponseEntity<?> getStuff(@PathVariable("id") long id) { 
    //the long id defined is the variable passed when making the petition through postman
    Entity entity =  entityService.getById(id);
    //for the entity it is supposed to be your model, and service
    if (entity == null) {
        return new ResponseEntity<ErrorDTO>(new ErrorDTO(
         // the ErrorDTO is a file where you get all the descriptions
                "did not find any id  " + id), HttpStatus.NOT_FOUND);

    }
    return new ResponseEntity<Entity>(entity, HttpStatus.OK);

}

因为我有一些downvotes我无法评论，人们不理解我所说的...所以换句话说它就像这样.. EDITED
