4、spring-mybatis.xml

<!-- 用于直指定配置文件的位置信息，在dataSource中可以使用 -->
	<context:property-placeholder location="classpath:jdbc.properties"
		ignore-unresolvable="true" />

		</property>
	</bean>

	<!-- MapperScannerConfigurer配置 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- basePackage指定要扫描的包，在此包之下的映射器都会被搜索到。可指定多个包，包与包之间用逗号或分号分隔 -->
		<property name="basePackage" value="com.zf.dao" />
	</bean>

	<!-- 配置事务管理器 -->
	<bean id="transactionManager"
