1.  方式一：通过jxl jar包来解析xls文件
2.  方式二：通过poi jar包来解析xls文件[https://blog.csdn.net/weixin\_43923436/article/details/90605636][https_blog.csdn.net_weixin_43923436_article_details_90605636]
3.  个人建议使用poi 来解析，因为jxl目前没有维护了，而且对日期时间的处理不友好，本人开始是使用的jxl，但是因为有时间的问题，进而使用poi，但是刚刚看到对时间可以处理了，我再尝试一下
    
        /注意，这里的两个参数，第一个是表示列的，第二才表示行
            cell=sheet.getCell(j, i);
            //要根据单元格的类型分别做处理，否则格式化过的内容可能会不正确
            if(cell.getType()==CellType.NUMBER){
              System.out.print(((NumberCell)cell).getValue());
            }
            else if(cell.getType()==CellType.DATE){
              System.out.print(((DateCell)cell).getDate());
            }
            else{
              System.out.print(cell.getContents());
            }

1.添加支持导入xls文件的jar包

<dependency>
    		    <groupId>net.sourceforge.jexcelapi</groupId>

2.dao层接口

@Mapper
    public interface CompanyMemberUserMapper {
    
        int insertSelective(CompanyMemberUser record);
    
    	@Select("select admin_id adminId,agent_id agentId from cloud_gift.tb_company_member where id = #{companyMemberId}")
        Map<String, String> findIdByCompanyMemberId(String companyMemberId);
    
        @Select("select * from cloud_gift.tb_company_member_user where mobile = #{mobile} and     admin_id = #{adminId} and is_delete = 0 limit 1")
    	CompanyMemberUser findCompanyMemberUserByMobile(@Param("mobile")String mobile,@Param("adminId") String adminId);
    }

3.mybatis.xml 对应的插入到数据库的xml文件

<?xml version="1.0" encoding="UTF-8"?>
