springmvc+spring+mybatis整合：
1. 拷贝所需jar
2. 创建spring配置文件(beans.xml)
3. 配置数据源
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://127.0.0.1:3306/test"></property>
<property name="username" value="root"></property>
<property name="password" value=""></property>
</bean>
4.创建SqlSessionFactory实例：
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定数据源 -->
<property name="dataSource" ref="dataSource"/>
<!-- 指定mybatis的配置文件 -->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
5. 配置事务
<bean class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
6. 配置事务的传播特性
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*" read-only="true"/>
<tx:method name="get*" read-only="true"/>
<tx:method name="query*" read-only="true"/>
<tx:method name="add*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="del*" propagation="REQUIRED"/>
</tx:attributes>
</tx:advice>
7. 配置AOP
<!-- 配置AOP -->
<aop:config>
<!-- 切点 -->
<aop:pointcut expression="execution(* com.liu.service..*.*(..))" id="pointcut"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
</aop:config>
8. <!-- 映射接口 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.liu.mapper"></property>
</bean>
9. 配置DispatcherServlet
<!-- 配置Spring核心控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
10. 创建springmvc-servlet.xml配置文件：
<!-- 注解扫描器 -->
<context:component-scan base-package="com.liu"/>
<!-- 配置试图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<import resource="classpath:beans.xml"/>
