How Vbulletin Report Post Function Works

Ever wonder what Vbulletin Report Post function does? The message does not go anywhere to the AdminCP or ModCP. Instead it just sends out email to moderators of the respective forum. If no moderator is assigned to the forum, the email is sent to the Administrator of the forum. However, you can change the default behaviour from AdminCP->Vbulletin Options->User Infractions & Post Reporting Options->Post Reporting Email. There are three options to choose, No Email, Post to Moderator, Post to Moderators (default), Super Moderators and Administrators.

Making Your Spring Service Layer Classes Application Context Aware

Spring framework has a nice feature to make your service layer classes applciation context aware. Basically, wiht ApplicationContext you can get messages stored in properties file. For JSP pages this can be easily done with tag libraries. But from the service layer classes, it is quite difficult to get those MessageResourceBundel class and other configuration settings. By implementing ApplicationContextAware from your service layer class, you get a reference to the ApplicationContext object and read in whatever properties you want to read. Below is a code snippet:

public class xxxxController extends FormAction implements ApplicationContextAware{
..................


public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.appContext=applicationContext;
}
}

Once this code has be inserted, you are ready to get the messages in the properties file like this:

String message = appContext.getMessage("your desired message name", new Object[]{param1,param2}, Locale.getDefault());

where param1 and param2 are of any Object type that you want to inject to the message which has the format like this:

Hellow {0}, today is {1}......
