Class ViburGetConnectionTimeoutMonitor

java.lang.Object

com.atlassian.confluence.internal.database.ViburGetConnectionTimeoutMonitor

public class ViburGetConnectionTimeoutMonitor
extends Object

Listens for when we fail to get a JDBC connection from our connection pool, and makes that information available to whichever other part of the application might want to know.

For example, Hibernate when Hibernate calls DataSource.getConnection() and gets a SQLTimeoutException, it treats it like any other SQLException, which results in a generic server error. This results in a shitty user experience.

By exposing the "failed to get a connection within the timeout" condition, we can report this to the user more elegantly, e.g. return an HTTP 503 rather than a 500, or to render a dedicated "please try again" error message.
