1. Define a Aop:pointcut entry point, which is the specific service that needs to process the transaction
2. Define a specific how to do the guidance aop:advisor, the need to guide the pointcut is just defined pointcut. Guidance recommendations can be customized with a recommendation Txadvice
3.txAvice requires a database to be used, so a spring-specific managed transaction object Txmanager is required.
4.Spring Management transactions also require sessionfactory, so you configure a Sessionfactory property. In Sessionfactory, a data source is specified.
