有谁知道哪个类处理@Transactional注释？我正在专门寻找创建交易的源代码。
Does anyone know which class handles the @Transactional annotation? I am searching for the source code that creates the transaction, specifically.

我在这里对 @Transactional 的内容进行了深入的代码分析： http ://doanduyhai.wordpress.com/2011/11/20/spring-transactional-explained/
注意，本次分析仅关注JPA事务。我没有考虑数据库以外的数据源，但我想方法是类似的
I've done a deep code analysis for the @Transactional stuff here: http://doanduyhai.wordpress.com/2011/11/20/spring-transactional-explained/
Be carefull, this analysis only focus on JPA transaction. I did not consider datasources other than database but I guess the approach is similar
TransactionInterceptor< /code>处理拦截逻辑，但显然需要许多其他基础设施类的帮助。不过，这是最好的起点。当你开始研究源代码时，事务同步的东西是相当可怕的。@Transactional的处理，以及将其解析为中性事务描述符对象模型，是由AnnotationTransactionAttributeSource。TransactionInterceptorhandles the interception logic, but obviously with the assistance of a lot of other infrastructure classes. That's the best place to start, though. The transaction sync stuff is pretty fearsome when you start getting into the source code.The processing of
@Transactional, and its parsing into the neutral transaction descriptor object model, is done byAnnotationTransactionAttributeSource.
