spring与mybatis整合

本文属于工作杂记，临时存放，待整理。

实际项目中应用是在applicationContext.xml中配置，

为了显示清晰：拆分出专门的spring配置，

<!-- 自动扫描业务包 -->
<context:component-scan base-package="com.xxx.service" />

<!-- 数据源 -->
<jee:jndi-lookup id="jndiDataSource" jndi-name="java:comp/env/jdbc/datasource" />

<!-- 配置事务 -->
<bean id="txManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="jndiDataSource" />
</bean>
<!-- 配置基于注解的事物aop -->
<tx:annotation-driven transaction-manager="txManager" proxy-target-class="true"/>

至于mybatis的配置：**mapper.xml
