Confluence : Accessing Confluence Components From Plugin Modules
This page last changed on Jan 24, 2006 by jnolen.
Confluence is built around Spring, an open-source component framework for for Java. If you are familiar with Spring, then you may only wish to know that Confluence plugin modules (and their implementing classes) are autowired by name. Thus, if you want to access a Confluence component from your plugin, just include the appropriate setter method in your implementing class. If you want to write Confluence plugins but are unfamiliar with Spring, the rest of this page should give you more than enough information on how to have your plugin interact with Confluence. Interacting with ConfluenceWhen you are writing anything but the simplest Confluence plugin, you will need to interact with the Confluence application itself in order to retrieve, change or store information. This document describes how this can be done. Manager ObjectsAt the core of Confluence is a group of "Manager" objects. For example, the pageManager is in charge of Confluence pages, the spaceManager of spaces, the attachmentManager of attachments, and so on. Dependency InjectionTraditionally, in a component-based system, components are retrieved from some kind of central repository. For example, in an EJB-based system, you would retrieve the bean from the application server's JNDI repository. Confluence works the other way round. When a plugin module is instantiated, Confluence determines which components the module needs, and delivers them to it. Confluence determines which components a module needs by reflecting on the module's methods. Any method with a signature that matches a standard JavaBeans-style setter of the same name as a Confluence component will have that component passed to it when the module is initialised. So, if your plugin module needs to access the pageManager, all you need to do is put the following setter method on your module's implementing class: public void setPageManager(PageManager pageManager) { this.pageManager = pageManager; } More Information
