在 Spring 中使用事务时创建提交后 [英] Creating a post commit when using transaction in Spring

问题描述

由于某些原因，我使用 Spring PlatformTransactionManager 手动执行了事务提交和回滚，我需要做的是设置一个钩子，以便在事务提交后进行提交后操作.

Due to certain reasons i have manually performed transaction commit and roll back using Spring PlatformTransactionManager, what i need to do is setup a hook so that a post commit action takes place after transaction has been committed.

通过查看:

 void commit(TransactionStatus status) throws TransactionException;

如果没有抛出异常，除了假设交易成功之外，我无法确定如何确定交易成功.

I cant see how i can determine a transaction was successful other than assumming it so if no expception are thrown.

而且我可以使用 AOP 作为一种选择，但是如何以编程方式执行它，也许使用回调方法?

And i could use AOP as one option, but what about programmitcally doing it, maybe using callback method?

推荐答案

使用 TransactionSynchronizationManager 和 TransactionSynchronization

使用TransactionSynchronizationManager，您可以使用静态方法来获取有关当前事务的信息，并且您可以注册一个TransactionSynchronization，它允许您在调用时自动执行提交后那个

With TransactionSynchronizationManager, you have static methods to get information about current transaction, and you can register a TransactionSynchronization wich allows you to automatically do a post-commit as you call that

TransactionSynchronizationManager.registerSynchronization(new TransactionSynchronization(){
           void afterCommit(){
                //do what you want to do after commit
           }
})

请注意，TransactionSynchronization 是基于每个线程的(这对于基本的 Web 请求通常不是问题).

Be aware that the TransactionSynchronization is on a per-thread basis (which is often not a problem for a basic web request).
