普通的事务直接直接在spring-mybatis.xml中配置声明式事务便可,或在service/dao层直接用注解事务@Transactional,本文主要说在controller层添加事务。sql
在controller层添加事务主要看spring-mvc.xml配置文件中的<tx:******>和<aop:******>的配置,其中express
<tx:annotation-driven>必须,<tx:advice>、<aop:config>为声明式事务配置json
代码controller类中符合声明式事务的方法出错将进行事务回滚,不符合的不回滚spring-mvc
controller类中,不符合声明式事务的方法,也能够直接用注解式的事务,这样两种事务配合使用websocket
为何按spring 配置事务的通常做法没法配置在controller没起效果呢?如下是摘取网上别人(http://uule.iteye.com/blog/1852012)的总结mybatis
其实就是一个加载顺序的问题
首先使用了spring MVC的项目是不须要配置action bean 而是经过spring mvc的配置文件进行扫描注解加载的
spring事务配置文件还有上下文都是经过org.springframework.web.context.ContextLoaderListener加载的,
而spring MVC的action是经过org.springframework.web.servlet.DispatcherServlet加载的 这样就有个优先级的问题了 web是先启动ContextLoaderListener后启动DispatcherServlet 在ContextLoaderListener加载的时候action并没在容器中,因此如今使用AOP添加事务或者扫描注解都是无用的。 那么解决办法就是在DispatcherServlet 加载spring-MVC配置文件后再进行一次AOP事务扫描和注解事务扫描就OK了 <tx:annotation-driven transaction-manager="transactionManager"/> <aop:config> <aop:advisor advice-ref="transactionAdvice" pointcut="execution(* com.yang.web.*.action.*.*(..))"/> </aop:config>
