how to listen for clicks in Java (JFreeChart) using events?

This is the code I'm currently using:

@Override
public void mouseExited(MouseEvent e) {
    System.out.println("detectado");
}

You can use addChartMouseListener() to add a ChartMouseListener to your ChartPanel. For example, in BarChartDemo1, add the following:

chartPanel.addChartMouseListener(new ChartMouseListener() {

    public void chartMouseClicked(ChartMouseEvent e) {
        System.out.println(e.getEntity());
    }

    public void chartMouseMoved(ChartMouseEvent e) {}

});

To listen for clicks, you must check the type of event.

In particular, you override the

public void mouseClicked(MouseEvent ev)

method, which is part of the interface for MouseListeners.
