我想在我的Java Web應用程序中使用log4j2。Java如何配置log4j2
這是我的依賴關係樹印Maven的

我有點困惑日誌由庫使用的庫包含在我的應用程序，所以我不得不包括commons.logging，slf4和Apache log4j的2.0版-beta5。
我創建log4j2.xml文件，並在類路徑推杆吧，這是我的log4j2.xml
<?xml version="1.0" encoding="UTF-8"?>
<configuration status="debug" packages="com.mypackage.app">
<appenders>
<File name="APPENDER_FILE" fileName="logs/app.log" append="false">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %p [%C:%L] - %m%n"/>
</File>
<Console name="APPENDER_OUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %p [%C:%L] - %m%n"/>
</Console>
</appenders>
<loggers>
<root level="debug">
<appender-ref ref="APPENDER_OUT"/>
<appender-ref ref="APPENDER_FILE"/>
</root>
</loggers>
</configuration>
當應用程序開始在tomcat7遵循的消息出現在Eclipse控制檯

log4j:WARN Please initialize the log4j system properly.

我認爲消息是指log4j配置而不是log4j2。這樣對嗎？
我如何配置它只使用log4j2？
謝謝。
