htmlunit去除無用日志

困擾

當(dāng)前項(xiàng)目經(jīng)常會使用到htmlunit，但是每次都有一大堆的無用日志輸出呻纹，排查問題的時(shí)候經(jīng)常造成干擾堆生。所以研究了下如何去除日志专缠。

解決方案

針對不同的日志實(shí)現(xiàn)我收集了幾種不同的實(shí)現(xiàn)方案，以備后用

log4j

我使用的是slf4j-api和slf4j-log4j12和log4j
在配置文件log4j.properties中加入如下配置項(xiàng)

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");
