JSF如何在页面刷新时停止@ManagedBean类的自动方法调用

Question

In my XHTML page I'm calling a method from my @ManagedBean class. The method should be executed only when I click the link which to is linked the method:

  <h:link value="Continue Reading &raquo;" 
       outcome="contracts/resources/data/imag2_facebook.html"  
onclick="#{sessionFilter.incForLink2('contracts/resources/imagini/facebook.jpg','Facebook down? Current problems and status', 'contracts/resources/imagini/facebook.jpg')}" />

It's weird why the method is executed at every page refresh without clicking on the link. I want the method to execute only when I click on the link. I have also tried with h:commandLink but the results are the same. Do you have an idea what I need to change, or what is wrong? The @ManagedBean class is application scoped. The method I call is the following:

public void incForLink2(String link, String title, String imgAllLink) {
    Article article = links.get(link);
    if (article != null) {
        Integer pageHits = article.getPageHits();
        article.setPageHits(pageHits + 1);
        System.out.println(link + " = " + pageHits);
    } else {
        Article article1 = new Article(1, title, link, imgAllLink);
        links.put(link, article1);
    }
}

onClick is a handler for JavaScript in the webbrowser! The Method you call is Java and executed on the server!

Java renders the Website before the website is sent to the webbrowser, in this phase is the method is invoked. After the sending to the webbrowser the javascript can be executed, this is a second phase. You simply need a new request to the server for executing java-methods. I prefer to use a4j:jsFunction .
