spring部分：applicationContext.xml文件配置
1.配置数据源 dataSource
<!-- 配置数据源 -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/db_maven"/>
<property name="username" value="root"/>
<property name="password" value="oursql"/>
</bean>
2.配置sqlSessionFactory,
2.1 引入dataSource,
2.2 自动扫描mappers.xml文件,
2.3 引入mybatis配置文件
<!-- 配置mybatis的sqlSessionFactory -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mappers.xml文件 -->
<property name="mapperLocations" value="classpath:com/java/user/mappers/*.xml"></property>
<!-- mybatis配置文件 -->
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
</bean>
3.配置dao扫描器，扫描/mappers/*.xml对应的mapper接口类，需要引入sqlSessionFactory
<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.java.user.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
4.配置事务
<!-- (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>
<!-- 配置事务通知属性 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<!-- 定义事务传播属性 -->
<tx:attributes>
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="edit*" propagation="REQUIRED" />
<tx:method name="save*" propagation="REQUIRED" />
<tx:method name="add*" propagation="REQUIRED" />
<tx:method name="new*" propagation="REQUIRED" />
<tx:method name="set*" propagation="REQUIRED" />
<tx:method name="remove*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="change*" propagation="REQUIRED" />
<tx:method name="check*" propagation="REQUIRED" />
<tx:method name="get*" propagation="REQUIRED" read-only="true" />
<tx:method name="find*" propagation="REQUIRED" read-only="true" />
<tx:method name="load*" propagation="REQUIRED" read-only="true" />
<tx:method name="*" propagation="REQUIRED" read-only="true" />
</tx:attributes>
</tx:advice>
<!-- 配置事务切面 -->
<aop:config>
<aop:pointcut id="serviceOperation" expression="execution(* com.java.user.service.*.*(..))" />
<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" />
</aop:config>
