Spring invoke method before every method call

Is there any way to invoke a method before every method call for a bean?

Im using selenium and cucumber with spring. All the pages are singletons because of this and since I'm using @FindBy annotations I want to invoke PageFactory.initElements(driver, object) every time a page is used.

Using a standard page object pattern, this would be done by invoking it in the constructor.

What I'd like to avoid is to specify in each method the method like so:

public void clickThis() {
    PageFactory.initElements(driver, this)
    ...
}

public void clickThat() {
    PageFactory.initElements(driver, this)
    ...
}

I dont want to return the new page since they will not be able to be shared between features.

Spring has a great AOP support and you can get benefits of it.

What you have to do in order to solve your problem is.

  1. Enable aspects in Spring by adding a <aop:aspectj-autoproxy/> in your Spring configuration file.

  2. Create a simple class and register it as an Aspect.

Source:

<bean id="myAspect" class="some.package.MyFirstAspect">
   <!-- possible properties ... for instance, the driver. -->
</bean>

The MyFirstAspect class. Note that is marked with the @Aspect annotation. Within the class, you will have to create a method and register it as a @Before advice (an advice runs before, after or around a method execution). 

package some.package;
import org.aspectj.lang.annotation.Aspect;

@Aspect
public class MyFirstAspect {
    @Before("execution(* some.package.SomeClass.*(..))")
    public void initElements() {
        //your custom logic that has to be executed before the `clickThis`
    }
}

As kocko mentioned you could use aspects.

Beside that: I'm not sure if I understood you correctly, but do you really need to call initElements with each method-call? Or just when you create your page. In later case I would suggest to create an abstract page where you call your initElements-method and inherit every other page from it.
