本文整理了Java中javax.jcr.Session.getItem()方法的一些代码示例，展示了Session.getItem()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Session.getItem()方法的具体详情如下：
包路径：javax.jcr.Session
类名称：Session
方法名：getItem

Session.getItem介绍

[英]Returns the node at the specified absolute path in the workspace. If no such node exists, then it returns the property at the specified path.

This method should only be used if the application does not know whether the item at the indicated path is property or node. In cases where the application has this information, either #getNode or #getProperty should be used, as appropriate. In many repository implementations the node and property-specific methods are likely to be more efficient than getItem.
[中]返回工作区中指定绝对路径处的节点。如果不存在这样的节点，则返回指定路径上的属性。
仅当应用程序不知道指定路径中的项是属性还是节点时，才应使用此方法。如果应用程序包含此信息，则应酌情使用#getNode或#getProperty。在许多存储库实现中，特定于节点和属性的方法可能比getItem更有效。
