Spring管理iBatis事务
Spring管理iBatis事务
?
<sqlMapConfig> <sqlMap resource="com/angi/ibatis/maps/User.xml" /></sqlMapConfig>
?
?
?以上配置省去了transactionManager的配置，就会使用external（外部）事务管理（ExternalTransaction），即等同如下配置：
?
<sqlMapConfig> <transactionManager type="EXTERNAL"> <!--这个数据源其实没有什么意义，还是取上面的省略方式吧--> <dataSource type="DBCP"> </dataSource> </transactionManager> <sqlMap resource="com/angi/ibatis/maps/User.xml" /></sqlMapConfig>

1、TransactionProxyFactoryBean

2、TransactionInterceptor

3、AOP和TX配置
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "> <!-- DataSource --> <bean id="dataSource" value="SqlMapConfig.xml" /> <property name="dataSource" ref="dataSource" /> </bean> <bean id="transactionManager" ref="dataSource" /> </bean> <!-- 需要引入aop的命名空间 --> <aop:config> <!-- 切入点指明了在所有方法产生事务拦截操作 --> <aop:pointcut id="serviceMethods" expression="execution(* com.angi.ibatis.service.*.*(..))" /> <!-- 定义了将采用何种拦截操作，这里引用到 txAdvice --> <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethods" /> </aop:config> <!-- 需要引入tx的命名空间 --> <!-- 这是事务通知操作，使用的事务管理器引用自 transactionManager --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 指定哪些方法需要加入事务，这里懒惰一下全部加入，可以使用通配符来只加入需要的方法 --> <tx:method name="*" propagation="REQUIRED" /> </tx:attributes> </tx:advice> <bean id="userDAO" /> </property> </bean> <bean id="userService" /> </property> </bean></beans>

4、anotation
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd "> <!-- 需要引入tx的命名空间 --> <tx:annotation-driven transaction-manager="transactionManager" /> <!-- DataSource --> <bean id="dataSource" value="false"/>--> <property name="url"> <value>jdbc:mysql://localhost/test</value> </property> <property name="username"> <value>root</value> </property> <property name="password"> <value>mysql</value> </property> </bean> <!-- Spring iBatis Template --> <bean id="sqlMapClient" value="SqlMapConfig.xml" /> <property name="dataSource" ref="dataSource" /> </bean> <bean id="transactionManager" /> </property> </bean> <bean id="userDAO" /> </property> </bean> <bean id="userService" /> </property> </bean></beans>
