MyBatisPlus如何根据id批量查询？Required request parameter ‘id‘ for method 解决方法是看青戈大佬MybatisPlus的教程

    @PostMapping("/list")
    public List<code> queryCodeByIds( @RequestParam("id") List<Long> id){
        List<code> code = codeService.listByIds(id);
        return code;
    }

@Service
public class CodeService extends ServiceImpl<codeMapper, code> {
@Resource
codeMapper codeMapper;
}

    @PostMapping("/list")
    public Result selectAll(){
        List<code> codeList = codeService.list(new QueryWrapper<code>().orderByDesc("id"));
        return Result.success(codeList);
 
    }
