本文整理了Java中org.neo4j.kernel.configuration.Config.get()方法的一些代码示例，展示了Config.get()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。Config.get()方法的具体详情如下：
包路径：org.neo4j.kernel.configuration.Config
类名称：Config
方法名：get

Config.get介绍

[英]Retrieves a configuration value. If no value is configured, a default value will be returned instead. Note that null is a valid value.
[中]检索配置值。如果未配置任何值，将返回默认值。请注意，null是一个有效值。
