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。

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.
