本文介绍了@Transactional在Spring Web MVC中不起作用？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我在Spring MVC中调用EntityManager.persist（）时，虽然在方法中添加了 @Transactional ，但它可以在不整合spring mvc ：
HTTP错误500
访问/ ssshp / addDept / wwewd时出现问题。原因：
没有可用于当前线程的实际事务的EntityManager - 无法可靠地处理'persist'调用
导致：
javax.persistence.TransactionRequiredException：No EntityManager实际交易可用于当前线程 - 无法可靠地处理'坚持'调用

它困扰了我几天，我不知道如何解决这个问题。我已经通过移动< tx：annotation-driven transaction-manager =transactionManager解决了这个问题。 /> 从applicationContext.xml到dispatcher-servlet.xml，Web应用程序通常可以正常工作。它出现的原因是applicationContext.xml中的< tx：annotation-driven transaction-manager =transactionManager/> 仅用于应用程序上下文，例如。 @服务，@库，@组件。所以您需要将它添加到您的servlet上下文中以使事务可用。
The Exception emerges when I i invoke EntityManager.persist() in spring mvc although @Transactional is added on the method, it could work without integrating spring mvc：
HTTP ERROR 500

it has troubled me a couple days, i don't know how to tackle this issue.
解决方案
I have solved this issue by moving <tx:annotation-driven transaction-manager="transactionManager" />which is from applicationContext.xml to dispatcher-servlet.xml, the web application can normally work right now. the reason why it emerges is that <tx:annotation-driven transaction-manager="transactionManager" /> in applicationContext.xml only serve for application context,eg. @Service,@Repository,@Component. so you need to add it into your servlet context to make transaction available.
