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

Handler.setLevel介绍

[英]Sets the logging level of the messages logged by this handler, levels lower than this value will be dropped.
[中]设置此处理程序记录的消息的日志记录级别，低于此值的级别将被删除。

代码示例

@Override
public void setLevel(Level newLevel) throws SecurityException {
  super.setLevel(newLevel);
  Handler t = resolve();
  if(t!=null)
    t.setLevel(newLevel);
}

Handler consoleHandler = new ConsoleHandler();
consoleHandler.setLevel(Level.FINER);
Logger.getAnonymousLogger().addHandler(consoleHandler);
