Best practice to implement HttpServletRequest in Struts2?

Question

What is best practice to implement HttpServletRequest in Struts2?

ServletActionContext - directly accessing the getRequest method from the ServletActionContext class
ServletRequestAware : the action class implements ServletRequestAware interface

Also, if you feel the interface way is better but want to avoid annoying code repetitions, just put the interface and the setter in the BaseAction extended by the others, only once — Andrea Ligios, Mar 06 '17 at 11:27

I couldn't see (or find documentation about) the benefits of 2. vs 1.

So why should I prefer

public class MyAction extends ActionSupport implements ServletRequestAware {

    private HttpServletRequest request;

    @Override
    public void setServletRequest(HttpServletRequest request) {
        this.request = request;
    }
}

When is worth enough

HttpServletRequest request = ServletActionContext.getRequest();
