SpringMVC Spring MyBatis整合配置文件

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>

    <!-- 全局setting配置，根据需要添加 -->

    <!-- 配置别名 -->
    <typeAliases>
        <!-- 批量扫描别名 -->
        <package name="cn.itcast.ssm.po"/>
    </typeAliases>

    <!-- 配置mapper
    由于使用spring和mybatis的整合包进行mapper扫描，这里不需要配置了。
    必须遵循：mapper.xml和mapper.java文件同名且在一个目录
     -->

    <!-- <mappers>

    </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db.properties文件中的内容，db.properties文件中key命名要有一定的特殊规则 -->
    <context:property-placeholder location="classpath:db.properties" />
    <!-- 配置数据源 ，dbcp -->

    <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>
    <!-- sqlSessionFactory -->
    <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">
        <!-- 扫描包路径，如果需要扫描多个包，中间使用半角逗号隔开 -->
        <property name="basePackage" value="cn.itcast.ssm.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

<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 ">
<!-- 商品管理的service -->
<bean id="itemsService" class="cn.itcast.ssm.service.impl.ItemsServiceImpl"/>
</beans>

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
    对mybatis操作数据库事务控制，spring使用jdbc的事务控制类
-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <!-- 数据源
    dataSource在applicationContext-dao.xml中配置了
     -->
    <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="delete*" propagation="REQUIRED"/>
        <tx:method name="insert*" 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:method name="select*" propagation="SUPPORTS" read-only="true"/>
    </tx:attributes>
</tx:advice>
<!-- aop -->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* cn.itcast.ssm.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

<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/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 ">

    <!-- 可以扫描controller、service、...

    <!-- 使用 mvc:annotation-driven代替上边注解映射器和注解适配器配置
    mvc:annotation-driven默认加载很多的参数绑定方法，
    比如json转换解析器就默认加载了，如果使用mvc:annotation-driven不用配置上边的RequestMappingHandlerMapping和RequestMappingHandlerAdapter
    实际开发时使用mvc:annotation-driven
