spring事务配置

基于注解的事务配置--@Transactional

父容器排除 controller

<context:component-scan base-package="com.ant.server">    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /></context:component-scan>

子容器排除service

<context:component-scan base-package="com.ant.server">    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service" /></context:component-scan>

proxy-target-class=true 使用cglib代理service类

<tx:annotation-driven transaction-manager="txManager"  proxy-target-class="true" /><!-- 配置事务管理器 --><bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">    <property name="dataSource" ref="dataSource" /></bean>

事务不起作用时，判断servce实例是否是代理类：

AopUtils.isAopProxy(Object object)
AopUtils.isCglibProxy(Object object) //cglib
AopUtils.isJdkDynamicProxy(Object object) //jdk动态代理
