我浪费了很多时间来解决这个问题。但不能。也许很简单。
The jar file of application cant load the log4j.xml file which is the configuration file of log4j.
Here is the code i am using
应用程序的jar 文件无法加载log4j.xml 文件，它是log4j 的配置文件。
这是我正在使用的代码
import org.apache.log4j.xml.DOMConfigurator;
public class LoggerConfig {
public void configLogger()
{
DOMConfigurator.configure("log4j.xml");
}
}
Its a maven project. and my dir strucure is:
它是一个 Maven 项目。我的目录结构是：

resource
| com

| | | abc
| | | | test
| | | | | log4j.xml
My classpath file looks like:

<?xml version="1.0" encoding="UTF-8"?>

<classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/>
<classpathentry kind="output" path="target/classes"/>
</classpath>
My log4j.xml looks like
我的 log4j.xml 看起来像
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

</layout>
</appender>
<root>
<priority value="INFO" />
<appender-ref ref="console" />
<appender-ref ref="file" />
</root>
</log4j:configuration>

As per the DOMConfiguratorcode the argument passed to it is treated as a File name. Instead of that try using the classpath resource
根据DOMConfigurator代码，传递给它的参数被视为文件名。而不是尝试使用类路径资源
public void configLogger()
{
URL u = getClass().getClassLoader().getResource("com/my/abc/test/log4j.xml");
DOMConfigurator.configure(u);
}
