spring-mybatis文件

编写mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>

编写spring-mybatis.xml

<bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<!-- 初始化连接大小 -->
		<property name="initialSize" value="0" />
		<!-- 连接池最大使用连接数量 -->

		<property name="maxIdle" value="20" />

		<!-- 获取连接最大等待时间 -->

		<property name="testOnReturn" value="false" />

		<property name="logAbandoned" value="true" />

		<!-- 监控数据库 -->
		<!-- <property name="filters" value="stat" /> -->
		<property name="filters" value="mergeStat" />
	</bean>

编写sessionfactory，这个类在spring生命周期是singleton

<!-- 定义Spring与MyBatis整合的操作控制，此时数据库的连接对象取得由Spring负责 -->
	<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- Mybatis操作需要有数据库连接池的支持，所以此处将之前配置连接池设置到此类之中 -->
		<property name="dataSource" ref="dataSource" />
		<!-- 编写的mapper.xml -->
		<property name="mapperLocations" value="classpath:sona/rfk/mapping/*.xml"/>
		<!-- 配置所有资源文件的保存路径的资源匹配符 -->
		<property name="configLocation" value="classpath:mybatis/mybatis.cfg.xml" />
	</bean>

去除dao实现子类

<!-- 定义数据层子类的自动实现控制，这样才可以将DAO接口与映射文件整合在一起，该bean不需要做引用 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- 存放在sona.rfk下的包接口才可以被自动的映射实现子类,无需编写dao的实现子类 -->
		<property name="basePackage" value="sona.rfk.dao"/>
		<!-- 定义本次要使用的SessionFactory类型的对象，直接以Bean的名称进行导入 -->
		<property name="sqlSessionFactoryBeanName" value="sessionFactory"/>
	</bean>  

<!-- 注解方式配置事物 -->
	 <tx:annotation-driven transaction-manager="transactionManager" />

配置事物管理器使用jdbc事物管理

注解方式配置事务

<!-- 配置事务管理器 -->
	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource" />
	</bean>

<!-- 拦截器方式配置事物 -->
	<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<tx:method name="add*" propagation="REQUIRED" />
			<tx:method name="append*" propagation="REQUIRED" />
			<tx:method name="insert*" propagation="REQUIRED" />
			<tx:method name="save*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />
			<tx:method name="modify*" propagation="REQUIRED" />
			<tx:method name="edit*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />
			<tx:method name="remove*" propagation="REQUIRED" />
			<tx:method name="repair" propagation="REQUIRED" />
			<tx:method name="delAndRepair" propagation="REQUIRED" />

			<tx:method name="get*" propagation="SUPPORTS" />
			<tx:method name="find*" propagation="SUPPORTS" />
			<tx:method name="load*" propagation="SUPPORTS" />
			<tx:method name="search*" propagation="SUPPORTS" />
			<tx:method name="datagrid*" propagation="SUPPORTS" />

			<tx:method name="*" propagation="SUPPORTS" />
		</tx:attributes>
	</tx:advice>

进行aop切面

<aop:config>
		<aop:pointcut id="transactionPointcut" expression="execution(* com.xx.service.impl.*.*(..))" />
		<aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" />
	</aop:config>
