    </context:component-scan>

    <!--配置数据源, 整合其他框架,事务等.-->
    <!--导入资源文件-->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!--配置c3p0-->
    <bean id="datasource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

    <!--配置事务管理器-->
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--Spring要想能够管理事务必须控制数据库连接池-->
        <property name="dataSource" ref="datasource"></property>
    </bean>
    <!--启用事务注解-->

springMvc配置文件:

myBatis配置文件(主要留一些不太常用的配置,主要的配置通过Spring完成)

<configuration>
	<!--留一些不太常用的配置即可-->
	<settings>
		<!--开启全局二级缓存-->
		<setting name="cacheEnabled" value="true"></setting>
		<setting name="mapUnderscoreToCamelCase" value="true"/>
		<!--显示的指定每个我们需要更改的配置的值，即使他是默认的。防止版本更新带来的问题  -->
		<setting name="lazyLoadingEnabled" value="true"/>
		<setting name="aggressiveLazyLoading" value="false"/>
	</settings>
</configuration>
