Bean named 'transactionManager'

用Eclipse重新配置spring基于xml的声明式事务时报了这个错.

Bean named 'transactionManager' is expected to be of type 'org.aopalliance.aop.Advice' but was actually of type 'org.springframework.jdbc.datasource.DataSourceTransactionManager'

以为是不熟练Eclipse的配置导致的,找了很久.
最后认真看了看报错消息,名为'transactionManager'的bean 属于<aop:advice>里(我是这么理解的)

找到bean.xml,我在建立切入点与事务通知的关系的时候在ref里填入的事务管理器,实际上这是填通知类的,而通知类是 txadvice,很显然我引用错误,

transactionManager是事务管理器不是事务的通知

修改后就解决了

txadvice是事务的通知,它引用了事务管理器
