Mybatis-plus如何通过反射实现动态排序不同字段功能

	@LogOperation(name = "query urpOfi", objType = "Config")
    @GetMapping
    public ResponseEntity<DtoResponse<OfiDto>> queryOfi(
            @RequestParam(name = "pageSize", defaultValue = "-1", required = false) Integer pageSize,
            @RequestParam(name = "page", defaultValue = "-1", required = false) Integer page,
            @RequestParam(value = "sort", defaultValue = "", required = false) String sort,
            @RequestParam(value = "msFlag", defaultValue = "", required = false) String msFlag)
            throws UnsupportedEncodingException {
        sort = URLDecoder.decode(sort, StandardCharsets.UTF_8.toString());
        msFlag = URLDecoder.decode(msFlag, StandardCharsets.UTF_8.toString());
        余下省略......
