本文整理了Java中org.slf4j.Logger.isErrorEnabled()方法的一些代码示例，展示了Logger.isErrorEnabled()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.isErrorEnabled()方法的具体详情如下：
包路径：org.slf4j.Logger
类名称：Logger
方法名：isErrorEnabled

Logger.isErrorEnabled介绍

[英]Is the logger instance enabled for the ERROR level?
[中]是否为错误级别启用了记录器实例？

代码示例

代码示例来源：origin: spring-projects/spring-framework

public void error(Object message) {
  if (message instanceof String || this.logger.isErrorEnabled()) {
    this.logger.error(String.valueOf(message));
  }
}

  case TraceSystem.ERROR:
