同事事務也不生效

事務配置

	<!-- 事務管理器 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<!-- 資料來源 -->
		<property name="dataSource" ref="dataSource" />
	</bean>
	<!-- 通知 -->
	<tx:advice id="txAdvice" transaction-manager="transactionManager">

	<!-- 切面 -->
	<aop:config>
		<aop:advisor advice-ref="txAdvice"
			pointcut="execution(* com.ciguo.service.*.*(..))" />
	</aop:config>
 

	<!-- 資料庫連線池 -->
	<!-- 載入配置檔案 -->
	<context:property-placeholder location="classpath:resource/*.properties" />
	
	<!-- 配置掃描包，載入mapper代理物件 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.ciguo.mapper"></property>
		<property name="sqlSessionTemplateBeanName" value="sqlSessionTemplate"></property>
	</bean>
	
	<!-- 資料庫連線池 -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		destroy-method="close">
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="maxActive" value="10" />
		<property name="minIdle" value="5" />
	</bean>
	
	<!-- 配置sqlsessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"></property>
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	
	<!-- 建立一個sqlSession例項，執行緒安全的，可以在所有DAO例項共享，原理是將sqlSession，事務與當前執行緒掛鉤  -->
    <bean name="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate" destroy-method="close" scope="prototype">
        <constructor-arg index="0" ref="sqlSessionFactory" />
    </bean>
 

除錯很久沒排查到錯誤，最後想到是不是配置切點掃描表示式的問題，仔細看了切點表示式

execution(* com.ciguo.service.*.*(..))

execution(* com.ciguo.service.*.impl.*.*(..))

impl後面第一個 *  表示Java類，第二個 * 表示方法 這樣子就能掃描到了，重啟測試，
