前一章 搭建一个SSM项目 - 4:M--MyBatis

现在MyBatis和Spring有了，现在到了把MyBatis整合到Spring里的时候了。
spring-MyBatis的官方文档

1:Maven导入依赖包

    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>2.0.5</version>
    </dependency>
    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>druid</artifactId>
      <version>1.1.22</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-tx</artifactId>
      <version>${springVersion}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>${springVersion}</version>
    </dependency>

2:在beans.xml增加如下

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="url" value="jdbc:mysql://localhost:3306/test"/>
        <property name="username" value="root"/>
        <property name="password" value="12345678"/>
        <property name="driver">
            <bean class="com.mysql.cj.jdbc.Driver"/>
        </property>
    </bean>

    <bean id="accountDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
        <property name="mapperInterface" value="com.ppf.dao.IAccountDao"/>
        <property name="sqlSessionFactory" ref="sqlSessionFactory"/>
    </bean>

3:怎么用？

        ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
        IAccountDao dao = context.getBean("accountDao", IAccountDao.class);
        List<Account> accounts = dao.fetchSomeAccounts(0, 2);
