1、spring管理SqlSessionFactory、mapper

1）在classpath下创建mybatis/sqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

<!—使用自动扫描器时，mapper.xml文件如果和mapper.java接口在一个目录则此处不用定义mappers -->
<mappers>
<package name="cn.itcast.ssm.mapper" />
</mappers>
</configuration>

2）配置数据源、事务管理，配置SqlSessionFactory、mapper扫描器 applicationContext-dao.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd 
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">
<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:db.properties"/>
<!-- 数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
       <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="maxActive" value="30"/>
        <property name="maxIdle" value="5"/>
</bean>    


<!-- 让spring管理sqlsessionfactory 使用mybatis和spring整合包中的 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据库连接池 -->
        <property name="dataSource" ref="dataSource" />
        <!-- 加载mybatis的全局配置文件 -->
        <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" />
    </bean>
<!-- mapper扫描器 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 <property name="basePackage" value="cn.itcast.springmvc.mapper"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

</beans>

3）mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.itcast.ssm.mapper.ItemsMapper">
    
    <!-- sql片段 -->
    <!-- 商品查询条件 -->
    <sql id="query_items_where">
        <if test="items!=null">
            <if test="items.name!=null and items.name!=‘‘">
                and items.name like ‘%${items.name}%‘
            </if>
        </if>
    </sql>
        
    <!-- 查询商品信息 -->
    <select id="findItemsList" parameterType="queryVo" resultType="items">
        select * from items 
        <where>
            <include refid="query_items_where"/>
        </where>
    </select>
    

</mapper>

4）mapper接口

public interface ItemsMapper {
    //商品列表
    public List<Items> findItemsList(QueryVo queryVo) throws Exception;
}

2、Service由spring管理，spring对Service进行事务控制。

1）applicationContext-service.xml

2）配置事务管理器applicationContext-transaction.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd 
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd 
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd 
        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">

<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <!-- 数据源 -->
    <property name="dataSource" ref="dataSource"/>
</bean>


<!-- 通知 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
  <tx:attributes>
     <!-- 传播行为 -->
    <tx:method name="save*" propagation="REQUIRED"/>
    <tx:method name="insert*" propagation="REQUIRED"/>
    <tx:method name="delete*" propagation="REQUIRED"/>
    <tx:method name="update*" propagation="REQUIRED"/>
    <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
    <tx:method name="get*" propagation="SUPPORTS" read-only="true"/>
  </tx:attributes>
</tx:advice>

<!-- 切面 -->
<aop:config>
  <aop:advisor advice-ref="txAdvice"
  pointcut="execution(* cn.itcast.springmvc.service.impl.*.*(..))"/>
</aop:config>

</beans>

3）OrderService

public interface OrderService {
    
    //商品查询列表
    public List<Items> findItemsList(QueryVo queryVo)throws Exception;
}

    @Autowired
    private ItemsMapper itemsMapper;

    @Override
    public List<Items> findItemsList(QueryVo queryVo) throws Exception {
        //查询商品信息
        return itemsMapper.findItemsList(queryVo);
    }

}

4）Action

　　springmvc.xml

    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/tx 
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">
        
    <!-- 扫描controller注解,多个包中间使用半角逗号分隔 -->
    <context:component-scan base-package="cn.itcast.ssm.controller"/>
    
    <!--注解映射器 -->
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
    <!--注解适配器 -->
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>
    
    <!-- ViewResolver -->
