OPENFIRE 启动流程

在java>org>jivesoftware>openfire>starter，该类中的main方法启动,有图为证：

在start中方法分别调用unpackArchives和findParentClassLoader方法，确定openfire目录,并解压相关jia包，并创建一个org.jivesoftware.openfire.XMPPServer类的实例，有图为证：

在XMPPServer类中，依次执行start>initialize>locateOpenfire加载相关的配置文件,初始化缓存工厂设置相关的缓存大小，然后接着保存设置,在start方法中有一句判断： if (!setupMode) ，这里的setupMode是从openfire文件夹下的config文件夹下面的openfire.xml配置文件获取，有图为证：

如果想重置openfire或者设置数据库连接把setup设置为false就可以重新配置openfire了；如果已经设置为true了，则会执行verifyDataSource进行数据库验证，loadModules加载模块，initModules初始化模块，startModules启动模块,启动插件管理器 pluginManager.start();最后设置监听。

 private void loadModules() {
        // Load boot modules
        loadModule(RoutingTableImpl.class.getName());
        loadModule(AuditManagerImpl.class.getName());
        loadModule(RosterManager.class.getName());
        loadModule(PrivateStorage.class.getName());
        // Load core modules
        loadModule(PresenceManagerImpl.class.getName());
        loadModule(SessionManager.class.getName());
        loadModule(PacketRouterImpl.class.getName());
        loadModule(IQRouter.class.getName());
        loadModule(MessageRouter.class.getName());
        loadModule(PresenceRouter.class.getName());
        loadModule(MulticastRouter.class.getName());
        loadModule(PacketTransporterImpl.class.getName());
        loadModule(PacketDelivererImpl.class.getName());
        loadModule(TransportHandler.class.getName());
        loadModule(OfflineMessageStrategy.class.getName());
        loadModule(OfflineMessageStore.class.getName());
        loadModule(VCardManager.class.getName());
        // Load standard modules
        loadModule(IQBindHandler.class.getName());
        loadModule(IQSessionEstablishmentHandler.class.getName());
        loadModule(IQAuthHandler.class.getName());
        loadModule(IQPingHandler.class.getName());
        loadModule(IQPrivateHandler.class.getName());
        loadModule(IQRegisterHandler.class.getName());
        loadModule(IQRosterHandler.class.getName());
        loadModule(IQTimeHandler.class.getName());
        loadModule(IQEntityTimeHandler.class.getName());
        loadModule(IQvCardHandler.class.getName());
        loadModule(IQVersionHandler.class.getName());
        loadModule(IQLastActivityHandler.class.getName());
        loadModule(PresenceSubscribeHandler.class.getName());
        loadModule(PresenceUpdateHandler.class.getName());
        loadModule(IQOfflineMessagesHandler.class.getName());
        loadModule(IQPEPHandler.class.getName());
        loadModule(IQPEPOwnerHandler.class.getName());
        loadModule(MulticastDNSService.class.getName());
        loadModule(IQSharedGroupHandler.class.getName());
        loadModule(AdHocCommandHandler.class.getName());
        loadModule(IQPrivacyHandler.class.getName());
        loadModule(DefaultFileTransferManager.class.getName());
        loadModule(FileTransferProxy.class.getName());
        loadModule(MediaProxyService.class.getName());
        loadModule(PubSubModule.class.getName());
        loadModule(IQDiscoInfoHandler.class.getName());
        loadModule(IQDiscoItemsHandler.class.getName());
        loadModule(UpdateManager.class.getName());
        loadModule(FlashCrossDomainHandler.class.getName());
        loadModule(InternalComponentManager.class.getName());
        loadModule(MultiUserChatManager.class.getName());
        loadModule(ClearspaceManager.class.getName());
        loadModule(IQMessageCarbonsHandler.class.getName());

        // Load this module always last since we don't want to start listening for clients
        // before the rest of the modules have been started
        loadModule(ConnectionManagerImpl.class.getName());
        // Keep a reference to the internal component manager
        componentManager = getComponentManager();
    }

在启动加载模块的过程中会依次加载这些模块。这些模块全部直接继承或间接继承BasicModule类，BasicModule类继承Module接口,Module接口定义五个方法，有图为证：

执行完loadModules这个方法之后所有的模块都保存在 private Map<Class, Module> modules = new LinkedHashMap<Class, Module>(); 这个LinkedHashMap中，执行startModules()时回按顺序执行LinkedHashMap中键值的start方法.
