I am pumping existing JDBC connection using SessionFactory.openSession(Connection). Now in 4.0 this method is not available. Which method should I use for this?

You can use SessionFactory.withOptions() and SessionBuilder.connection(Connection connection).

SessionBuilder connection(Connection connection)

Adds a specific connection to the session options

Parameters: connection - The connection to use.

Returns: this, for method chaining

Example:

SessionBuilder sb = SessionFactory.withOptions();
Session session = sb.connection(connection).openSession();

    It may be a version thing, but withOptions() to me is shown as a non-static method. In this case, you need to create an instance of SessionFactory.

    @PauloMerson - agreed. This example (especially since it is the accepted answer) should be updated to make it clear that withOptions() is NOT a static method.
