不能拒絕HtmlUnit日誌記錄

Question

我正在使用org.apache.log4j.Logger並且想要關閉htmlunit的調試消息。我做的沒有任何事情似乎有效。我不斷收到Http.wire，Http.headers等調試消息。我有根記錄器設置爲DEBUG

我試圖把這個線在我的代碼：

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

我也試過把此行中我log4j.properties文件：

log4j.logger.com.gargoylesoftware.htmlunit=WARN 

這是我的log4j.properties文件的內容：

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 

任何幫助，將不勝感激。

Answer 1

因此，經過多次實驗和觀察日誌輸出我已經知道了這一點。事實證明，Apache HTTPCLient website上的HttpClient的文檔不正確（事實上存在斷開的鏈接）。事實證明，HTTPClient使用的記錄器名稱不是在doc中指定的。正確的記錄器根名稱是「http」而不是「httpclient」，這意味着我正在執行的所有試驗都沒有任何影響。

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）。

下面是一個例子log4j.properties文件，將允許精細控制HTMLClient日誌

# 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 

Answer 2

對於log4j的，你應該設置log4j.logger.com.gargoylesoftware.htmlunit到ERROR：

log4j.logger.com.gargoylesoftware.htmlunit=ERROR 

第二個選項：在你的代碼，聲明後添加此您的網絡客戶端：

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);
