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,  
  VU_USER_NAME VARCHAR(20) not null,  
  VU_PASSWORD  VARCHAR(20) not null,  
  VU_STATUS    int(6) not null,  
  VU_VERSION   int(8) not null  
); 
   
create table VOTE_SUBJECT 
( 
  VS_ID    int(8) primary key, 
  VS_TITLE VARCHAR(200) not null, 
  VS_TYPE  int(6) not null 
); 
 
create table VOTE_OPTION 
( 
  VO_ID     int(8) primary key, 
   VS_ID     int(8) not null, 
  VO_OPTION VARCHAR(200) not null, 
  VO_ORDER  int(8) not null 
); 
 
create table VOTE_ITEM 
( 
  VI_ID      int(8) primary key, 
  VS_ID      int(8) not null, 
  VO_ID      int(8) not null, 
  VU_USER_ID int(8) not null 
);

use vote;

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
