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

Session.nodeExists介绍

[英]Returns true if a node exists at absPath and this Session has read access to it; otherwise returns false.
[中]如果absPath上存在一个节点，并且该Session具有对该节点的读取权限，则返回true；否则返回false。

    if (!configSession.nodeExists(SECURITY_CONFIG_PATH)) {
      return null;
    }
    Session usersSession = MgnlContext.getJCRSession(RepositoryConstants.USERS);
    if (usersSession.nodeExists(SYSTEM_SUPERUSER_PATH)) {
      reload();
    }
    return null;
  }
});
