log4j无法使用我的log4j.properties初始化 [英] log4j can't initialize with my log4j.properties
本文介绍了log4j无法使用我的log4j.properties初始化的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个简单的log4j.property文件和一个使用log4j的简单程序.但是当我运行我的罐子时,我只会看到
I have a simple log4j.property file and a simple program that use log4j. But when I run my jar I see only this
log4j:WARN No appenders could be found for logger (package com.mycompany.hellolog4j).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
这是我使用记录器的方式:
Here is how I use logger:
package com.mycompany.hellolog4j;
import java.io.File;
import java.io.IOException;
import org.apache.log4j.*;
public class SimpleLogging
{
public static void main(String args[]) throws IOException {
Logger logger = Logger.getLogger(SimpleLogging.class.getPackage().toString());
// SimpleLogging demo = new SimpleLogging(rbName);
//demo.doLogging(name);
logger.info("printing the message...");
}
}
这是我pom.xml的一部分
And this is part of my pom.xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathLayoutType>custom</classpathLayoutType>
<mainClass>com.mycompany.hellolog4j.SimpleLogging</mainClass>
<customClasspathLayout>../lib/log4j.jar ../log4j.properties</customClasspathLayout>
</manifest>
</archive>
</configuration>
</plugin>
这是我的log4j.properties
And here is my log4j.properties
log4j.rootLogger = DEBUG, testAppender
log4j.logger.com.mycompany.hellolog4j=DEBUG, testAppender
log4j.appender.testAppender=org.apache.log4j.ConsoleAppender
log4j.appender.testAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.testAppender.layout.conversionPattern=%p-%m%n
现在从我的项目目录中运行jar文件.这是我的项目目录
Now from my project directory I run jar file. This is my project directory
drwxr-xr-x 5 proger users 4096 2010-10-15 22:59 ./
drwxr-xr-x 3 proger users 4096 2010-10-15 22:27 ../
drwxr-xr-x 2 proger users 4096 2010-10-14 22:54 lib/
-rw-r--r-- 1 proger users 291 2010-10-15 23:00 log4j.properties
-rw-r--r-- 1 proger users 1689 2010-10-15 22:59 nbactions.xml
-rw-r--r-- 1 proger users 1987 2010-10-15 22:56 pom.xml
drwxr-xr-x 4 proger users 4096 2010-10-13 23:01 src/
drwxr-xr-x 6 proger users 4096 2010-10-15 22:59 target/
推荐答案
将log4j.properties文件放在src/main/resources中,以便将其捆绑到您的JAR文件中,并因此捆绑到类路径中.
Put the log4j.properties file in src/main/resources so that it is bundled into your JAR file, and thus on the classpath.
