本文整理了Java中javax.jcr.Session.itemExists()方法的一些代码示例，展示了Session.itemExists()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.itemExists()方法的具体详情如下：
包路径：javax.jcr.Session
类名称：Session
方法名：itemExists

Session.itemExists介绍

[英]Returns true if an item exists at absPath and this Session has read access to it; otherwise returns false.
[中]如果某个项目存在于absPath并且该Session具有读取权限，则返回true；否则返回false。
