不能拒绝HtmlUnit日志记录

Question

我正在使用org.apache.log4j.Logger并且想要关闭htmlunit的调试消息。我做的没有任何事情似乎有效。我不断收到Http.wire，Http.headers等调试消息。我有根记录器设置为DEBUG

我试图把这个线在我的代码：

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

我也试过把此行中我log4j.properties文件：

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，将不胜感激。

因此，经过多次实验和观察日志输出我已经知道了这一点。事实证明，Apache HTTPCLient website上的HttpClient的文档不正确（事实上存在断开的链接）。事实证明，HTTPClient使用的记录器名称不是在doc中指定的。正确的记录器根名称是“http”而不是“httpclient”，这意味着我正在执行的所有试验都没有任何影响。

我使用的是org.apache.httpcomponents.httpclient_4.5.2和org.apache.httpcomponents.httpcore_4.4.5，截至今天（11/15/16）。

下面是一个例子log4j.properties文件，将允许精细控制HTMLClient日志

# 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

对于log4j的，你应该设置log4j.logger.com.gargoylesoftware.htmlunit到ERROR：

log4j.logger.com.gargoylesoftware.htmlunit=ERROR 

第二个选项：在你的代码，声明后添加此您的网络客户端：

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);
