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：
1. <!-- 引入jdbc配置文件 -->
2. <context:property-placeholder location="jdbc.properties"/>
3. <!--创建jdbc数据源 -->
4. <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
5. <property name="driverClassName" value="${driver}"/>
6. <property name="url" value="${url}"/>
7. <property name="username" value="${username}"/>
8. <property name="password" value="${password}"/>
9. <property name="initialSize" value="${initialSize}"/>
10. <property name="maxActive" value="${maxActive}"/>
11. <property name="maxIdle" value="${maxIdle}"/>
12. <property name="minIdle" value="${minIdle}"/>
13. </bean>
14. <!-- 创建SqlSessionFactory，同时指定数据源-->
15. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
16. <property name="dataSource" ref="dataSource" />
17. </bean>
18. <!--创建数据映射器，数据映射器必须为接口-->
19. <bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
20. <property name="mapperInterface" value="com.xxt.ibatis.dbcp.dao.UserMapper" />
21. <property name="sqlSessionFactory" ref="sqlSessionFactory" />
22. </bean>
23. <bean id="userDaoImpl2" class="com.xxt.ibatis.dbcp.dao.impl.UserDaoImpl2">
24. <property name="userMapper" ref="userMapper"/>
25. </bean>
（2）数据映射器UserMapper,代码如下:
1. public interface UserMapper {
2. @Select("SELECT * FROM user WHERE id = #{userId}")
3. @Param("userId") long id);
4. }(3) dao接口类UserDao，代码如下：
1. public interface UserDao {
2. public User getUserById(User user);
3. }(4)dao实现类UserDaoImpl2,，代码如下:
1. public class UserDaoImpl2 implements UserDao {
2. private UserMapper userMapper;
3. public void setUserMapper(UserMapper userMapper) {
4. this.userMapper = userMapper;
5. }
6. public User getUserById(User user) {
7. return userMapper.getUser(user.getId());
8. }
9. }
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：
1. <!-- 创建SqlSessionFactory，同时指定数据源-->
2. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
3. <property name="dataSource" ref="dataSource" />
4. <!-- 指定sqlMapConfig总配置文件，订制的environment在spring容器中不在生效-->
5. <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
6. <!--指定实体类映射文件，可以指定同时指定某一包以及子包下面的所有配置文件，mapperLocations和configLocation 有一个即可，当需要为实体类指定别名时，可指定configLocation属性，再在mybatis总配置文件中采用mapper引入实体类映射文件 -->
7. <property name="mapperLocations" value="classpath*:com/xxt/ibatis/dbcp/**/*.xml"/> -->
8. </bean>
9. <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
10. <constructor-arg index="0" ref="sqlSessionFactory" />
11. </bean>
12. <bean id="UserDaoImpl " class="com.xxt.ibatis.dbcp.dao.impl.UserDaoImpl">
13. <!--注入SqlSessionTemplate实例 -->
14. <property name="sqlSessionTemplate" ref="sqlSession" />
15. -->
16. </bean>(2)mybatis总配置文件sqlMapConfig.xml：
1. <configuration>
2. <typeAliases>
3. <typeAlias type="com.xxt.ibatis.dbcp.domain.User" alias="User" />
4. </typeAliases>
5. <mappers>
6. <mapper resource="com/xxt/ibatis/dbcp/domain/user.map.xml" />
7. </mappers>
8. </configuration>(3)实体类映射文件user.map.xml:
1. <mapper namespace="com.xxt.ibatis.dbcp.domain.User">
2. <resultMap type="User" id="userMap">
3. <id property="id" column="id" />
4. <result property="name" column="name" />
5. <result property="password" column="password" />
6. <result property="createTime" column="createtime" />
7. </resultMap>
8. <select id="getUser" parameterType="User" resultMap="userMap">
9. id = #{id}
10. </select>
11. <mapper/>(4)dao层接口实现类UserDaoImpl：
1. public class UserDaoImpl implements UserDao {
2. public SqlSessionTemplate sqlSession;
3. public User getUserById(User user) {
4. return (User)sqlSession.selectOne("com.xxt.ibatis.dbcp.domain.User.getUser", user);
5. }
6. public void setSqlSession(SqlSessionTemplate sqlSession) {
7. this.sqlSession = sqlSession;
8. }
9. } 3、采用抽象类org.mybatis.spring.support.SqlSessionDaoSupport提供SqlSession。
(1)spring配置文件:
1. <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
2. <property name="dataSource" ref="dataSource" />
3. <property name="configLocation" value="classpath:sqlMapConfig.xml"/>
4. <!-- <property name="mapperLocations" value="classpath*:com/xxt/ibatis/dbcp/domain/user.map.xml"/ > -->
5. </bean>
6. <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
7. <constructor-arg index="0" ref="sqlSessionFactory" />
8. </bean>
9. <bean id="userDaoImpl3" class="com.xxt.ibatis.dbcp.dao.impl.UserDaoImpl3">
10. <!--注入SqlSessionTemplate实例 -->
11. <property name="sqlSessionTemplate" ref="sqlSession" />
12. <!--也可直接注入SqlSessionFactory实例，二者都指定时，SqlSessionFactory失效 -->
13. <!-- <property name="sqlSessionFactory" ref="sqlSessionFactory" />
14. -->
15. </bean> (2) dao层接口实现类UserDaoImpl3：
1. public class UserDaoImpl3 extends SqlSessionDaoSupport implements UserDao {
2. public User getUserById(User user) {
3. return (User) getSqlSession().selectOne("com.xxt.ibatis.dbcp.domain.User.getUser", user);
4. }
5. }org.mybatis.spring.mapper.MapperFactoryBean或者org.mybatis.spring.mapper.MapperScannerConfigurer
1. <beans:bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
2. <beans:property name="dataSource" ref="simpleDataSource" />
3. <beans:property name="configLocation"
4. value="classpath:conf/core/mybatis-config.xml" />
