spring+springmvc+springjdbc实现读取xls文件并插入到数据库中

环境说明：spring+springmvc+springJdbc 数据库为，mysql8.0

1、表字段类型：


SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for `user`
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `roleId` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
  `username` varchar(255) DEFAULT NULL,
  `password` varchar(255) DEFAULT NULL,
  `company_name` varchar(255) DEFAULT NULL,
  `company_code` varchar(255) DEFAULT NULL,
  `region_code` varchar(255) DEFAULT NULL,
  `first_cp_code` varchar(255) DEFAULT NULL,
  `second_cp_code` varchar(255) DEFAULT NULL,
  `first_industry_code` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`roleId`)
) E

2、xls文件数据（fileTest1.xls）：

roleId	username	password	company_name	company_code	region_code	first_cp_code	second_cp_code	first_industry_code
101	张三	123456	华智	1492	test1	test2	test3	test4
102	张三	123456	华智	1492	test1	test2	test3	test4
103	张三	123456	华智	1492	test1	test2	test3	test4
104	张三	123456	华智	1492	test1	test2	test3	test4
105	张三	123456	华智	1492	test1	test2	test3	test4
