如何在Tomcat中將級別日誌記錄設置爲DEBUG？

Question

我想在tomcat中設置級別日誌記錄到DEBUG，但是在控制檯中只有INFO和WARN輸出。 有人可以告訴我什麼是錯的？

我的C：\ Tomcat的\ logging.properties：

首先，使用級別名稱爲FINE，不DEBUG。假設一分鐘即DEBUG實際上是有效的，因爲它使下面的解釋讓更多的感覺......

在Handler specific properties部分，你對這些處理的日誌記錄級別設置爲DEBUG。這意味着處理程序將處理任何具有DEBUG級別或更高級別的日誌消息。這並不意味着任何DEBUG消息實際上都會傳遞給處理程序。

在Facility specific properties部分，您將幾個明確指定的記錄器的記錄級別設置爲DEBUG。對於那些伐木者，任何級別爲DEBUG或以上的將傳遞給處理程序。

默認日誌記錄級別爲INFO，除了Facility specific properties部分中提到的日誌記錄程序外，所有日誌記錄程序都具有該級別。

如果你想看到所有FINE信息，補充一點：

.level = FINE 

但是，這會生成日誌消息的一個巨大的數量。這可能更有用日誌記錄級別設置爲您的代碼：

your.package.level = FINE 

見Tomcat 6/Tomcat 7日誌文件以獲取更多信息。有顯示的示例logging.properties文件使用FINE而不是DEBUG：

... 
1catalina.org.apache.juli.FileHandler.level = FINE 
... 

，也爲您提供了額外的設置日誌級別的示例：

# For example, set the com.xyz.foo logger to only log SEVERE 
# messages: 
#org.apache.catalina.startup.ContextConfig.level = FINE 
#org.apache.catalina.startup.HostConfig.level = FINE 
#org.apache.catalina.session.ManagerBase.level = FINE
