在JSF中加載頁面之前，我們如何調用方法？

Question

@ManagedBean(name="bean") 
@SessionScoped 
public class MyBean{ 

@PostConstruct 
public void postConstruct() 
{ 
System.out.println("Inside post Construct"); 
} 

public void beforePageLoad() 
{ 
System.Out.println("Called before pageload for session scoped bean!!!"); 
} 
} 


How can we call beforePageLoad method everytime before the page loads.

你的頁面內：

<f:metadata> 
    <f:event type="preRenderView" listener="#{bean.listener}"/> 
</f:metadata>
