本文主要介绍Spring与Mybatis三种常用整合方法，需要的整合架包是mybatis-spring.jar，可通过链接

http://code.google.com/p/mybatis/下载到。

1、采用数据映射器（MapperFactoryBean）的方式，不用写mybatis映射文件，采用注解方式提供相应的sql语句和输入参数。

（1）Spring配置文件：

<> <context:property-placeholder location="jdbc.properties"/> <> <bean id="dataSource" destroy-method="close"> <property name="driverClassName" value="${driver}"/> <property name="url" value="${url}"/> <property name="username" value="${username}"/> <property name="password" value="${password}"/> <property name="initialSize" value="${initialSize}"/> <property name="maxActive" value="${maxActive}"/> <property name="maxIdle" value="${maxIdle}"/> <property name="minIdle" value="${minIdle}"/> </bean> <> <bean id="sqlSessionFactory"> <property name="dataSource" ref="dataSource" /> </bean> <> <bean id="userMapper"> <property name="mapperInterface" value="com.xxt.ibatis.dbcp.dao.UserMapper" /> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> </bean> <bean id="userDaoImpl2"> <property name="userMapper" ref="userMapper"/> </bean>

(2)数据映射器UserMapper,代码如下:

public interface UserMapper { @Select("SELECT * FROM user WHERE id = #{userId}") User getUser(@Param("userId") long id); }

(3)dao接口类UserDao，代码如下：

public interface UserDao { public User getUserById(User user); }

(4)dao实现类UserDaoImpl2,，代码如下:

public class UserDaoImpl2 implements UserDao { private UserMapper userMapper; public void setUserMapper(UserMapper userMapper) { this.userMapper = userMapper; } public User getUserById(User user) { return userMapper.getUser(user.getId()); } }

2、采用接口org.apache.ibatis.session.SqlSession的实现类org.mybatis.spring.SqlSessionTemplate。

mybatis中, sessionFactory可由SqlSessionFactoryBuilder.来创建。

MyBatis-Spring 中，使用了SqlSessionFactoryBean来替代。

SqlSessionFactoryBean有一个必须属性dataSource，另外其还有一个通用属性configLocation（用来指定mybatis的xml配置文件路径）。

（1）Spring配置文件：

<>

<bean id="sqlSessionFactory">

<property name="dataSource" ref="dataSource" />

<>

<property name="configLocation" value="classpath:sqlMapConfig.xml"/>

<>

<!- - <property name="mapperLocations" value="classpath*:com/xxt/ibatis/dbcp/**/*.xml"/> -->

<bean>

(2)mybatis总配置文件sqlMapConfig.xml：

<configuration> <typeAliases> <typeAlias type="com.xxt.ibatis.dbcp.domain.User" alias="User" /> </typeAliases> <mappers> <mapper resource="com/xxt/ibatis/dbcp/domain/user.map.xml" /> </mappers> </configuration>

(3)实体类映射文件user.map.xml:

<mapper namespace="com.xxt.ibatis.dbcp.domain.User"> <resultMap type="User" id="userMap"> <id property="id" column="id" /> <result property="name" column="name" /> <result property="password" column="password" /> <result property="createTime" column="createtime" /> </resultMap> <select id="getUser" parameterType="User" resultMap="userMap"> select * from user where id = #{id} </select> <mapper/>

(4)dao层接口实现类UserDaoImpl：

Java代码

public class UserDaoImpl implements UserDao { public SqlSessionTemplate sqlSession; public User getUserById(User user) { return (User)sqlSession.selectOne("com.xxt.ibatis.dbcp.domain.User.getUser", user); } public void setSqlSession(SqlSessionTemplate sqlSession) { this.sqlSession = sqlSession; } }

3、采用抽象类org.mybatis.spring.support.SqlSessionDaoSupport提供SqlSession。

(1)spring配置文件:

Java代码

<bean id="sqlSessionFactory"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:sqlMapConfig.xml"/> <> </bean> <bean id="sqlSession" > <constructor-arg index="0" ref="sqlSessionFactory" /> </bean> <bean id="userDaoImpl3"> <> <property name="sqlSessionTemplate" ref="sqlSession" /> <> <> </bean>

(2) dao层接口实现类UserDaoImpl3：

Java代码

public class UserDaoImpl3 extends SqlSessionDaoSupport implements UserDao { public User getUserById(User user) { return (User) getSqlSession().selectOne("com.xxt.ibatis.dbcp.domain.User.getUser", user); } }
