普通的事務直接直接在spring-mybatis.xml中配置聲明式事務便可,或在service/dao層直接用註解事務@Transactional,本文主要說在controller層添加事務。sql
在controller層添加事務主要看spring-mvc.xml配置文件中的<tx:******>和<aop:******>的配置,其中express
<tx:annotation-driven>必須,<tx:advice>、<aop:config>爲聲明式事務配置json
代碼controller類中符合聲明式事務的方法出錯將進行事務回滾,不符合的不回滾spring-mvc
controller類中,不符合聲明式事務的方法,也能夠直接用註解式的事務,這樣兩種事務配合使用websocket
爲何按spring 配置事務的通常做法沒法配置在controller沒起效果呢?如下是摘取網上別人(http://uule.iteye.com/blog/1852012)的總結mybatis
其實就是一個加載順序的問題
首先使用了spring MVC的項目是不須要配置action bean 而是經過spring mvc的配置文件進行掃描註解加載的
spring事務配置文件還有上下文都是經過org.springframework.web.context.ContextLoaderListener加載的,
而spring MVC的action是經過org.springframework.web.servlet.DispatcherServlet加載的 這樣就有個優先級的問題了 web是先啓動ContextLoaderListener後啓動DispatcherServlet 在ContextLoaderListener加載的時候action並沒在容器中,因此如今使用AOP添加事務或者掃描註解都是無用的。 那麼解決辦法就是在DispatcherServlet 加載spring-MVC配置文件後再進行一次AOP事務掃描和註解事務掃描就OK了 <tx:annotation-driven transaction-manager="transactionManager"/> <aop:config> <aop:advisor advice-ref="transactionAdvice" pointcut="execution(* com.yang.web.*.action.*.*(..))"/> </aop:config>
