I have seem the demo of vaadin 8 charts use:
public class SplineUpdatingEachSecond extends AbstractVaadinChartExample

So.I need this AbstractVaadinChartExample class.

You can find it here, in the Charts sources, as well as all of the demo code: https://github.com/vaadin/charts/blob/master/examples/src/main/java/com/vaadin/addon/charts/examples/AbstractVaadinChartExample.java
