本文整理了Java中org.apache.juli.logging.Log.isWarnEnabled()方法的一些代码示例，展示了Log.isWarnEnabled()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。Log.isWarnEnabled()方法的具体详情如下：
包路径：org.apache.juli.logging.Log
类名称：Log
方法名：isWarnEnabled

Log.isWarnEnabled介绍

[英]Is warn logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than warn.
[中]当前是否启用了警告日志记录？
调用此方法以防止在日志级别超过warn时执行昂贵的操作（例如，String串联）。
