mybatis自动生成mapper,dao,映射文件

一.先创建数据脚本，这里用的mysql数据脚本

[java] view
plaincopy

drop table FILMINFO;

drop table FILMTYPE;

create table FILMINFO

(

FILMID int primary key auto_increment,

FILMNAME VARCHAR(50) not null,

TYPEID int not null,

ACTOR VARCHAR(255),

DIRECTOR VARCHAR(50),

TICKETPRICE int not null

);

alter table FILMINFO auto_increment = 10001;

create table FILMTYPE

(

TYPEID int primary key auto_increment,

TYPENAME VARCHAR(20)

);

alter table FILMTYPE auto_increment = 100001;

insert into FILMTYPE(TYPENAME) values('爱情片');

insert into FILMTYPE(TYPENAME) values('动作片');

insert into FILMTYPE(TYPENAME) values('喜剧片');

insert into FILMTYPE(TYPENAME) values('战争片');

insert into FILMTYPE(TYPENAME) values('科幻片');

insert into FILMTYPE(TYPENAME) values('恐怖片');

insert into FILMTYPE(TYPENAME) values('动画片');

insert into FILMTYPE(TYPENAME) values('其它片');

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('阿凡达', 10005, '萨姆·沃辛顿,佐伊·索尔达娜,西格妮·韦弗,乔·摩尔,拉兹·阿隆索,乔瓦尼·瑞比西', '詹姆斯·卡梅隆', 150);

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('猫和老鼠', 10007, '汤姆,杰瑞', 'William Hanna,Joseph Barbera', 60);

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('大兵小将', 10002, '成龙,王力宏,刘承俊,林鹏,徐冬梅,杜玉明', '丁晟', 50);

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('大侦探福尔摩斯', 10002, '小罗伯特·唐尼,裘德·洛', '盖·里奇', 100);

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('全城热恋', 10001, '谢霆锋,张学友 ,刘若英,徐若瑄,徐熙媛', '夏永康,陈国辉', 80);

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('第九区', 10005, '沙尔托·科普雷,詹森·库伯,威廉·艾伦·扬', '尼尔·布洛姆坎普', 100);

insert into FILMINFO(FILMNAME,TYPEID,ACTOR,DIRECTOR,TICKETPRICE) values('敢死队3', 10002, '西尔维斯特·史泰龙，杰森·斯坦森，梅尔·吉布森，李连杰，阿诺·施瓦辛格，杜夫·龙格尔', '派特里克·休斯', 250);

commit;

select * from FILMTYPE;

select * from FILMINFO;

Linux下操作命令:

[plain] view
plaincopy

create database cinema character set utf8;

use cinema;

source 全路径下的脚本文件地址

generator.xml文件

[java] view
plaincopy

<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->

<table tableName="FILMINFO" domainObjectName="FilmInfo" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />

<table tableName="FILMTYPE" domainObjectName="FilmType" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />

</context>

</generatorConfiguration>

要修改的地方，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，还所最后注释上说的

[java] view
plaincopy

<!-- 要生成那些表(更改tableName和domainObjectName就可以) -->

最后写个运行脚本，window下创建bat后缀文件,Linub下创建sh后缀文件

[java] view
plaincopy

@echo '开始'

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite

@echo '结束'

@pause
