方法名：getEventJournal

ObservationManager.getEventJournal介绍

[英]Retrieves the event journal for this workspace. If journaled observation is not supported for this workspace, null is returned. Events recorded in the EventJournal instance will be filtered according to the current session's access rights as well as any additional restrictions specified through implemention-specific configuration.
[中]检索此工作区的事件日志。如果此工作区不支持日志观察，则返回null。EventJournal实例中记录的事件将根据当前会话的访问权限以及通过特定于实现的配置指定的任何附加限制进行过滤。
