 <!-- 自动扫描 -->
 <context:component-scan base-package="com.hua.saf" />
 <!-- 引入配置文件 -->
 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
 <property name="location" value="classpath:jdbc.properties" />
 </bean>
 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
 <property name="driverClassName" value="${driver}" />
 <property name="url" value="${url}" />
 <property name="username" value="${username}" />
 <property name="password" value="${password}" />
 <!-- 初始化连接大小 -->
 <property name="initialSize" value="${initialSize}" />
 <!-- 连接池最大数量 -->
 <property name="maxActive" value="${maxActive}" />
 <!-- 连接池最大空闲 -->
 <property name="maxIdle" value="${maxIdle}" />
 <!-- 连接池最小空闲 -->
 <property name="minIdle" value="${minIdle}" />
 <!-- 获取连接最大等待时间 -->
 <property name="maxWait" value="${maxWait}" />
 </bean>
 <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
 <property name="dataSource" ref="dataSource" />
 <!-- 自动扫描mapping.xml文件，**表示迭代查找 -->
 <property name="mapperLocations" value="classpath:com/hua/saf/**/*.xml" />
 </bean>
 <!-- DAO接口所在包名，Spring会自动查找其下的类 ,包下的类需要使用@MapperScan注解,否则容器注入会失败 -->
 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 <property name="basePackage" value="com.hua.saf.*" />
 <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
 </bean>
 <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
 <property name="dataSource" ref="dataSource" />
 </bean> 
</beans>
