困扰
当前项目经常会使用到htmlunit，但是每次都有一大堆的无用日志输出，排查问题的时候经常造成干扰。所以研究了下如何去除日志。

解决方案
针对不同的日志实现我收集了几种不同的实现方案，以备后用
log4j
我使用的是slf4j-api和slf4j-log4j12和log4j
在配置文件log4j.properties中加入如下配置项
log4j.logger.httpclient.wire=fatal
log4j.logger.org.apache.commons=fatal
log4j.logger.com.gargoylesoftware.htmlunit=fatal
log4j.logger.com.gargoylesoftware.htmlunit.WebTestCase=fatal
log4j.logger.com.gargoylesoftware.htmlunit.javascript.DebugFrameImpl=fatal
java.util.logging
在方法中加入如下行
java.util.logging.Logger.getLogger("com.gargoylesoftware").setLevel(Level.OFF);
org.apache.commons.logging.Log
在方法中加入如下行
LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog");
