我正在尝试通过以下方式在我的 Java EE 应用程序中使用 log4j 进行日志记录,其中我在应用程序中定义了 log4j.xml。
我正在尝试使用
DOMConfigurator.configure( "src/log4j.xml");
logger.warn( "Login Process has started a warning message" );
但它不断抛出以下错误
** 编辑错误信息
log4j:ERROR Could not parse file [src/log4j.xml].
java.io.FileNotFoundException: D:\src\log4j.xml (The system cannot find the path s pecified)

当我提供绝对路径时,一切正常。
那么实现这一点的方法是什么?我正在使用 1.2.16.jar 版本的 log4j
每次构建应用程序时都会收到以下警告
log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
编辑:应用程序结构
Myapp
src
conf
target
我已经在文件夹 src 下放置了 log4j.xml
log4j.xml 文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="console" class="org.apache.log4j.ConsoleAppender">

<layout class="org.apache.log4j.PatternLayout">

</layout>
</appender>
<logger name="com.web" additivity="false">

谢谢
