我目前正在开发一个使用带有cassandra作为数据库的spring boot的应用程序 .
我写了一个初始化我的cassandra集群的类 . 在我的DAO图层查询方法中开始使用@Transactional时，问题就开始了 . 系统不允许我在运行时抛出以下错误消息时使用它们 -
An exception has occured in method getMdoBean with msg: No qualifying bean of type 'org.springframework.transaction.PlatformTransactionManager' available.
我不明白出了什么问题 . 我的应用程序没有 spring 启动工作正常，没有与事务管理相关的问题 .
我尝试添加JPA支持和H2数据库，它解决了我的问题 . 我完成了我的作业并阅读了H2数据库及其内存数据存储机制 . 我无法理解TransactionManagement问题是如何解决的？是因为H2数据库驱动程序正在处理它吗？
其次，我不需要H2数据库因此这个解决方案对我来说似乎并不好 . 后端是Cassandra的应用程序 . 任何线索都会有所帮助 . 谢谢！

如果我在方法级别使用上述类中的@Transactional，则不允许在没有为JPA添加H2支持的情况下使用@Transactional . 在POM中放置下面的代码行后，它工作正常 .
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
</dependency>

我想原因是你排除
HibernateJpaAutoConfiguration，有没有理由这样做，否则我建议你把它添加回来，也许还要添加@EnableTransactionManagement给你的配置类 .
