Hi Luffy,

When you click button on a VF page you can call appropriate action, invoking respective method within the Controller Class. And if your need is to invoke the same method but wish to identify the button from which it is invoked then you can use <apex:param> component.

VF Page - 
<apex:commandButton action="{! button }" title="Button1" value="Button 1" reRender="pb" >
                	<apex:param name="button1" value="Button 1" />
                <apex:commandButton action="{! button }" title="Button2" value="Button 2" reRender="pb" >
                	<apex:param name="button2" value="Button 2" />

Controller Code - 
public PageReference button() {
        //--- Here you can check which button was clicked and then perform respective action
        buttonName = ApexPages.currentPage().getParameters().get('button1');
        System.debug('Output = ' + butName);
        buttonName = ApexPages.currentPage().getParameters().get('button2');
        System.debug('Output = ' + butName);        
        return null;
