mybaits用使用map传参，实现多条件查询

有个需求需要实现多条件查询，然后mybaits使用map进行参数的传递，刚开始的时候一直报错：Caused by: org.apache.ibatis.binding.BindingException: Parameter ‘pcode’ not fond，就是说我的参数一直传不进去。然后去搜了一下，才发现我的map传参有问题
接下来直接上代码吧

//controller层
public Result<?> searchPolice(PageInfo pageInfo, @RequestBody JSONObject jsonObject) {
    
    
        Result<Page<PoliceInfo>> result = new Result<>();
        try {
    
    
            Map<String, Object> map = jsonObject.getInnerMap();
            Page<PoliceInfo> page = new Page<>(pageInfo.getCurrentPage(), pageInfo.getPageSize());
            List<PoliceInfo> list = policeInfoService.getPoliceInfoByConditions(page, map);
            page.setRecords(list);
            result.setSuccess(true);
            result.setCode(200);
            result.setResult(page);
        } catch (Exception e) {
    
    
            result.error500("查询失败" + e.getMessage());
            log.error(e.getMessage(), e);
        }
        return result;
    }
//service层
 public List<PoliceInfo> getPoliceInfoByConditions(Page page, Map<String, Object> map) {
    
    
        return policeInfoMapper.getPoliceInfoByConditions(page, map);
    }
//mapper层
 List<PoliceInfo> getPoliceInfoByConditions(Page page, @Param("params") Map<String, Object> map);
//xml文件

记录一下第一次用map传参留下的坑~
