首先簡歷數(shù)據(jù)庫demo(本文選mysql)

數(shù)據(jù)庫腳本：

?

CREATE?TABLE?`ibatis`?(
??`id`?varchar(20)?NOT?NULL,
??`name`?varchar(20)?default?NULL,
??PRIMARY?KEY??(`id`)
)?ENGINE=InnoDB?DEFAULT?CHARSET=gb2312;

insert?into?ibatis?values("1","1");
insert?into?ibatis?values("2","2");

?

DAO接口：

?

package?ch10.SpringAndIbatis;

import?java.util.List;

public?interface?IDAO?...{
??public?List?getList();
??public?Ibatis?getByName(String?name);
??public?Ibatis?getById(String?id);
??public?void?save(Ibatis?ibatis);
??public?void?delete(String?id);
??public?void?update(Ibatis?ibatis);
}

?

Ibatis配置文件：

?

<?xml?version="1.0"?encoding="UTF-8"?>?
<!DOCTYPE?sqlMapConfig?
PUBLIC?"-//iBATIS.com//DTD?SQL?Map?Config?2.0//EN"?
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">?
<sqlMapConfig>?

<sqlMap?resource="ch10/SpringAndIbatis/Ibatis.xml"?/>?

</sqlMapConfig>

ibatis sql map文件ibatis.xml：

?

DAO實現(xiàn)類：
