Possibility of intercepting method getConnection() if exception is thrown by original DataSource about datasource-proxy HOT 2 CLOSED

ah ok, yes it has a problem in the current ProxyDataSource implementation.

Instead, what you can do as a workaround is to create a pure proxy for DataSource.

DataSource original = ...

ProxyConfig proxyConfig = ProxyConfig.Builder.create().methodListener(methodListener).queryListener(listener).build();
DataSource proxy = proxyConfig.getJdbcProxyFactory().createDataSource(original, proxyConfig);

Note: since you mentioned afterGetConnection method, I assume you are using JdbcLifecycleEventListener.
This one is a bit tricky to register to ProxyConfig. Please check how ProxyDataSourceBuilder#listener(JdbcLifecycleEventListener) method registers the listener to ProxyConfig if that is the case.

Yes, this approach works exactly as I want. Thank you!
