本文整理了Java中java.util.logging.Logger.setLevel()方法的一些代码示例，展示了Logger.setLevel()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。Logger.setLevel()方法的具体详情如下：
包路径：java.util.logging.Logger
类名称：Logger
方法名：setLevel

Logger.setLevel介绍

[英]Set the log level specifying which message levels will be logged by this logger. Message levels lower than this value will be discarded. The level value Level.OFF can be used to turn off logging.

If the new level is null, it means that this node should inherit its level from its nearest ancestor with a specific (non-null) level value.
