jxl读写excel, poi读写excel,word, 读取Excel数据到MySQL
这篇blog是介绍:
1. java中的poi技术读取Excel数据,然后保存到MySQL数据中。
2. jxl读写excel
你也可以在 : java的poi技术读取和导入Excel了解到写入Excel的方法信息
项目结构:
Excel中的测试数据:
数据库结构:
对应的SQL:
1 CREATE TABLE `student_info` ( 2 `id` int(11) NOT NULL AUTO_INCREMENT, 3 `no` varchar(20) DEFAULT NULL, 4 `name` varchar(20) DEFAULT NULL, 5 `age` varchar(10) DEFAULT NULL, 6 `score` float DEFAULT '0', 7 PRIMARY KEY (`id`) 8 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
插入数据成功:
如果重复数据,则丢掉:
