mybatis自己主动生成mapper,dao,映射文件
一.先创建数据脚本，这里用的mysql数据脚本
drop table VOTE_ITEM;
drop table VOTE_OPTION;
drop table VOTE_SUBJECT;
drop table VOTE_USER;
create table VOTE_USER
(
VU_USER_ID int(8) primary key,

要改动的地方，驱动包的路径，mysql包的路径。链接数据库的配置。生成包的路径，还所最后凝视上说的
<!-- 要生成那些表(更改tableName和domainObjectName就能够) -->
最后写个执行脚本，window下创建bat后缀文件,Linub下创建sh后缀文件
@echo '開始' java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite @echo '结束'
@pause
上面的认为麻烦就直接输入中间那一行代码就能够跑起来了
