使用iBATIS3.0完成增删改查

iBATIS3.0和以前的版本有一些改变，不过学过以前版本的再学习3.0应该不是太难，3.0要求JDK1.5支持，因为其中增加了注解和泛型，这些都是JDK1.5才有的。好了废话不多说，先来利用iBATIS3做下简单的增删改查吧。
首先到Apache(http://www.apache.org/)网站下载iBATIS3的jar 包，我下载的是ibatis-3-core-3.0.0.227.zip，解压后吧那个jar文件（ibatis-3-core-3.0.0.227.jar）添加到工程就可以了，还有一个文件（ibatis-3-core-src-3.0.0.227.zip）是源代码，可以用来查看源代码的，使用eclipse可以用它来关联源代码。
在MyEclipse新建一个Java Project，结构如下图
在jdbc.properties文件是映射文件要使用的，其内容如下：
Properties代码
driver=com.mysql.jdbc.Driver url=jdbc\:mysql\://localhost\:3306/test username=root password=123456
SqlMapper.xml是iBATIS的配置文件，其代码如下：
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-config.dtd">
<configuration>
<properties resource="jdbc.properties"/>
<typeAliases>
<typeAlias type="cn.ibatis3.test.Person" alias="Person"/>
</typeAliases>
<environments default="development">
<environment id="development">
<transactionManager type="JDBC"/>
<dataSource type="POOLED">
<property name="driver" value="${driver}"/>
<property name="url" value="${url}"/>
<property name="username" value="${username}"/>
<property name="password" value="${password}"/>
</dataSource>
</environment>
</environments>
<mappers>
<mapper resource="cn/ibatis3/test/person.xml"/>
</mappers>
</configuration>
上面文件中的sql映射文件person.xml代码如下：
Xml代码
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN"
"http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd">
<!-- -->
<mapper namespace="cn.ibatis3.test.PersonMapper">
<select id="selectPerson" parameterType="java.lang.Integer"
resultType="Person">
select * from person where id = #{id}
</select>
<select id="selectAll" resultType="Person">
select * from person
</select>
<select id="selectPersonsByName" resultType="Person" parameterType="String">
select * from person where name like #{name}
</select>
<insert id="insertPerson" parameterType="Person">
insert into person(name,birthday,sex)
values(#{name},#{birthday},#{sex})
</insert>
<delete id="deletePerson" parameterType="Person">
delete from person where id=#{id}
</delete>
<update id="updatePerson" parameterType="Person">
update person set name=#{name},birthday=#{birthday},sex=#{sex}
where id=#{id}
</update>
</mapper>
注意：在iBATIS3中，属性parameterMap是不推荐使用的，在以后的版本可能会去掉这个属性。
Person.java的代码如下：
Java代码
package cn.ibatis3.test;
import java.util.Date;
public class Person {
private int id = 0;
private String name = "";
private String sex = "male";
private Date birthday = null;
public Person() {
}
//省略getter 和 setter 方法
@Override
public String toString() {
return "id=" + id + "\t" + "name=" + name + "\t" + "sex=" + sex + "\t"
+ "birthday=" + new java.sql.Date(birthday.getTime()).toString();
}
}
iBATIS官方推荐我们使用单例模式创建一个sessionFactory，我这里也提供一个sessionFactory.java，呵呵,仅供参考：
Java代码
package cn.ibatis3.test;
import java.io.IOException;
import java.io.Reader;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
public final class SessionFactory {
private String resource="cn/ibatis3/test/SqlMapper.xml";
private SqlSessionFactory sqlSessionFactory=null;
private static SessionFactory sessionFactory=new SessionFactory();
private SessionFactory() {
try {
Reader reader=Resources.getResourceAsReader(resource);
sqlSessionFactory=new SqlSessionFactoryBuilder().build(reader);
} catch (IOException e) {
System.out.println("#IOException happened in initialising the SessionFactory:"+e.getMessage());
throw new ExceptionInInitializerError(e);
}
}
public static SessionFactory getInstance() {
return sessionFactory;
}
public SqlSessionFactory getSqlSessionFactory() {
return sqlSessionFactory;
}
}
基于接口的编程（还有就是iBATIS3的注解也是在接口方法上的，关于注解以后有机会再讲，它也是iBATIS3的一个新特性），DAO层的接口PersonMapper.java代码如下：
Java代码
package cn.ibatis3.test; import java.util.List; public interface PersonMapper { Person selectById(Integer id); List<Person> selectAll(); List<Person> selectPersonsByName(String name); void insert(Person person); void delete(Person person); void update(Person person); }
接口的实现类PersonDao.java代码如下：
Java代码
package cn.ibatis3.test;
import java.util.ArrayList;
import java.util.List;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
public class PersonDao implements PersonMapper {
private SqlSessionFactory sessionFactory = SessionFactory.getInstance()
.getSqlSessionFactory();
public Person selectById(Integer id) {
Person person = new Person();
SqlSession session = null;
try {
session = sessionFactory.openSession();
person = (Person) session.selectOne(
"cn.ibatis3.test.PersonMapper.selectPerson", id);
} finally {
session.close();
}
return person;
}
@SuppressWarnings("unchecked")
public List<Person> selectAll() {
List<Person> persons = new ArrayList<Person>();
SqlSession session = null;
try {
session = sessionFactory.openSession();
persons = session
.selectList("cn.ibatis3.test.PersonMapper.selectAll");
} finally {
session.close();
}
return persons;
}
public void delete(Person person) {
SqlSession session = null;
try {
session = sessionFactory.openSession();
session.delete("cn.ibatis3.test.PersonMapper.deletePerson", person);
session.commit();
} finally {
session.close();
}
}
public void insert(Person person) {
SqlSession session = null;
try {
session = sessionFactory.openSession();
session.insert("cn.ibatis3.test.PersonMapper.insertPerson", person);
session.commit();
} finally {
session.close();
}
}
public void update(Person person) {
SqlSession session = null;
try {
session = sessionFactory.openSession();
session.insert("cn.ibatis3.test.PersonMapper.updatePerson", person);
session.commit();
} finally {
session.close();
}
}
@SuppressWarnings("unchecked")
public List<Person> selectPersonsByName(String name) {
List<Person> persons = new ArrayList<Person>();
SqlSession session = null;
try {
session = sessionFactory.openSession();
System.out.println(name);
persons = session.selectList(
"cn.ibatis3.test.PersonMapper.selectPersonsByName", "%"
+ name + "%");
session.commit();
} finally {
session.close();
}
return persons;
}
}
最后是表的创建：
Sql代码
DROP TABLE IF EXISTS `test`.`person`; CREATE TABLE `test`.`person` ( `id` int(10) unsigned NOT NULL auto_increment, `name` varchar(20) default NULL, `sex` varchar(8) default NULL, `birthday` datetime default NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
