No qualifying bean of type 'org.springframework.transaction.TransactionManager' available

这个错误的原因是在项目中配置了多个数据源，但在使用@Transactional()注解时没有直接指定使用的事务管理器，导致Spring无法确定具体使用哪一个事务管理器来进行事务管理。解决这个问题的方法是通过在@Transactional注解中指定使用的事务管理器，可以使用@Transactional(transactionManager = "xxTransactionManager")来进行指定。另外，还需要确保配置的事务管理器对象上添加了@Bean注解，以便Spring能够扫描到它们。\[1\]\[2\]\[3\]
