經(jīng)常需要用到excel導入數(shù)據(jù)庫的同學，其實可以不用每次費事編寫POI-java代碼，現(xiàn)在maven可以方便的半自動導入，只需要配置好相關(guān)設(shè)置，方便了許多
示例使用mysql DB

excel內(nèi)容格式如下

按照excel格式建立對應(yīng)的表結(jié)構(gòu)

SET SESSION FOREIGN_KEY_CHECKS=0;

/* Drop Tables */
DROP TABLE learn_maven_list;

/* Create Tables */

CREATE TABLE `learn_maven_list` (
    `id` VARCHAR(64) NOT NULL COLLATE 'utf8_bin',
    `license_no` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    `appler` VARCHAR(255) NOT NULL COLLATE 'utf8_bin',
    `farm` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    `address` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    `contect` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    `product` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    `large` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    `date` DATE NULL DEFAULT NULL,
    `pirorid` VARCHAR(255) NULL DEFAULT NULL COLLATE 'utf8_bin',
    PRIMARY KEY (`id`),
    INDEX `appler` (`appler`, `id`)
)
COLLATE='utf8_bin'
ENGINE=InnoDB;

注意表名應(yīng)該和excel的sheet名一致，如果有多個sheet，依次建立表結(jié)構(gòu)即可

文件中的wee.properties中需要定義好datasouce

#============================#
#===== Database sttings =====#
#============================#

#mysql database setting
jdbc.type=mysql
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/learn_maven?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=

最后執(zhí)行批處理文件

@echo off
echo [INFO] Re-create the schema and provision the sample data.
pause

cd %~dp0
cd ..

set path=%MAVEN_HOME%/bin;%windir%/system32;%path%
call mvn antrun:run -Pinit-db

cd db
pause

導入成功
