Spring数据@Transactional不回滚

时间：2013-05-07 09:42:59

标签： spring jpa repository rollback transactional

我使用Spring MVC和Spring JPA开发了我的第一个应用程序。使用@Transactional注释时遇到问题。我使用@Transactional注释我的一个服务方法，并在该方法中抛出异常，因为我希望它会被回滚，但事实并非如此。

这是我的配置文件和我的类文件内容：

在AttributeService.java中，在save方法中，您可以找到：

t = attributeRepository.save(t);

if(t.getId() > 1){
            throw new Exception();
        }

所以在我调用save之后，我立即抛出一个异常，但后来我检查了数据库并且它没有回滚。

我真的很感谢你们的任何帮助， 谢谢！

2 个答案:

答案 0 :(得分：3)

我发现了问题。在app-context.xml和servlet-context.xml中，两者都有<context:component-scan/>。该标记将导致此链接中解释的问题： Spring @Transactional annotations ignored

答案 1 :(得分：1)

您的Attribute课程没有id字段。它来自AbstractPersistable<Long>你能说明你是如何注释ID字段的吗？是Auto generated吗？

根据上面的答案，可能存在几种可能的事情。 1.你的Id永远不会变成大于1 而且永远不会抛出异常

我建议尝试下面的代码并告诉我即使在它之后事务没有回滚。 

t = attributeRepository.save(t);
throw new Exception();

同时显示id中Attribute class的映射方式代码将有助于您提供帮助

您调用AttributeService Save方法的方式和位置也会影响交易。这部分代码也会有所帮助。
