oracle结合mybatis批量插入数据

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:

    <!-- 插入从工厂抽取的易贷数据的放款计划信息  -->
<insert id="insertYdData" parameterType="java.util.List">
            insert into t_rb_xdhj_lend

1、新增的数据含有ORACLE自增长序列；
2、union all 会报ORA:02287-此处不允许序号；
