先上代码：

controller:

result = service.insertTRbXdhjLendYdData(params);

service:

List<TRbXdhjLendDTO> dtoList = (List<TRbXdhjLendDTO>) paramMap.get("jsonList");
        //批量插入
        dao.insertYdData(dtoList);

dao:

/**
     * 存储从工厂库抽取的易贷数据的放款信息
     * @param paramMap
     * @return
     */
    public int insertYdData(List<TRbXdhjLendDTO> list);

mapper:
