Listener on transaction start
<p>I am looking for a clean solution to have a listener for transaction start. That means I would like the listener to be a bean (component) in the spring context that would receive an event on transaction start from TransactionPlatformManager or Hibernate Session or something similar, at the point where a new transaction is started.</p>

<p>Something along:</p>

<pre><code>@Component
class TransactionListener implements ?? {

    @Autowired
    private Something x;

    public void onTransactionBegin(...) {
        x.doSomething()
    }

}
</code></pre>

<p>To be concrete, I am mitigating a system wide problem and I need to set a thread local when transaction starts, so I can access that thread local further in the processing of hibernate entities to retrieve info.</p>

<p>I looked into sources and found no traces for such listener to be achievable. The only solution I found was to subclass HibernateTransactionManager and its doBegin() method, which I don't find particularly nice.</p>
