在Spring中使用事务时创建一个post提交 [英] Creating a post commit when using transaction in Spring

问题描述

由于某些原因，我已经手动执行了事务提交并使用Spring PlatformTransactionManager回滚，我需要做的是设置一个钩子，以便在提交事务后进行事后提交操作。

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;

我无法确定如何确定交易是否成功，除了假设它如此，如果没有抛出任何指示。

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

我可以使用AOP作为一个选项，但是程序化做什么呢，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

你可以通过一种更简单的方式得到你想要的东西，用 TransactionSynchronizationManager 和 TransactionSynchronization

You could get exactly what you want by a simpler way, with TransactionSynchronizationManager and TransactionSynchronization

使用 TransactionSynchronizationManager ，您可以使用静态方法获取有关当前事务的信息，并且可以注册 TransactionSynchron ization 它允许你在调用时自动进行提交

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基于每个线程（对于基本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).
