Question

我正在使用org.apache.log4j.Logger并想关闭htmlunit的调试消息。我所做的一切似乎都没有用。我不断收到Http.wire，Http.headers等调试信息。我将根记录器设置为调试

我尝试将此行放在我的代码中：

org.apache.log4j.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(org.apache.log4j.Level.OFF);

我也尝试将此行放在我的log4j.properties文件中：

log4j.logger.com.gargoylesoftware.htmlunit=WARN

这是我的log4j.properties文件的内容：

log4j.logger.com.gargoylesoftware.htmlunit=ERROR

log4j.logger.org.apache.commons.httpclient=ERROR


# Tell the root lodger what appenders and level to use
log4j.rootLogger=DEBUG, A1, A2


##### Console Appender #####

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d %-5p [%t] %-17c{2} (%13F:%L) %3x - %m%n


##### File Appender #####

log4j.appender.A2=org.apache.log4j.FileAppender
log4j.appender.A2.File=/var/log/mylogfile.log
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%d %-5p [%t] %-17c{2} (%13F:%L) %3x - %m%n
log4j.appender.A2.Append=false

任何帮助都将不胜感激。

        Logger.getRootLogger().debug("Start");

        WebClient webClient = new WebClient()

        HtmlPage page = webClient.getPage("https://google.com");

        Logger.getRootLogger().debug("End");
    }

Answer 1

对于log4j，您应将log4j.logger.com.gargoylesoftware.htmlunit设置为ERROR：

log4j.logger.com.gargoylesoftware.htmlunit=ERROR

第二个选项：在您的代码中，在声明您的Web客户端之后添加它：

LogFactory.getFactory().setAttribute("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.NoOpLog");

java.util.logging.Logger.getLogger("com.gargoylesoftware.htmlunit").setLevel(Level.OFF); 
java.util.logging.Logger.getLogger("org.apache.commons.httpclient").setLevel(Level.OFF);

因此，经过多次试验和观察日志输出后，我已经想到了这一点。事实证明，Apache HTTPCLient website 上的HttpClient文档不正确（事实上，链接已断开）。事实证明，HTTPClient使用的记录器的名称不是doc中指定的。正确的记录器根名称为＆＃34; http＆＃34;不是＆＃34; httpclient＆＃34;这意味着我所进行的所有试验都没有效果。

我正在使用org.apache.httpcomponents.httpclient_4.5.2和org.apache.httpcomponents.httpcore_4.4.5，截至今日（11/15/16）。

这是一个示例log4j.properties文件，可以精确控制HTMLClient日志记录

# Tell the root logger what appenders and level to use
log4j.rootLogger=DEBUG, A1, A2


# Controls detailed wire protocol
log4j.logger.org.apache.http.wire=WARN

# Controls headers (good for debugging)
log4j.logger.org.apache.http.headers=WARN

# Controls http context (what you are sending and geting)
log4j.logger.org.apache.http=WARN

# Controls htmlunit details
log4j.logger.com.gargoylesoftware.htmlunit=WARN


##### Console Appender #####

log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%d %-5p [%t] %-17c{2} (%13F:%L) %3x - %m%n


##### File Appender #####

log4j.appender.A2=org.apache.log4j.FileAppender
log4j.appender.A2.File=mylogfile.log
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%d %-5p [%t] %-17c{2} (%13F:%L) %3x - %m%n
log4j.appender.A2.Append=false
