将 log4j.properties 放在 Maven 项目中的什么位置？

Question

我知道这是一个陈词滥调的问题，我阅读了所有文档并尝试了很多解决方案，但始终没有适合我的解决方案！！但我把 log4j.properties 放在 src/main/resources 和 src/main/java 并且我已经将 PropertyConfigurator.configure("log4j.properties"); 添加到我的 class 但是当我将我的项目变成 可运行的 JAR 它告诉我：

C:\Users\eya\Desktop>java -jar RestCallAutomation.jar
log4j:WARN No appenders could be found for logger (com.infosquare.restautomation.AppController).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
log4j:ERROR Could not read configuration file [log4j.properties].

log4j:ERROR Ignoring configuration file [log4j.properties].

这是我的项目的架构： maven project Architecture

这里是 log4j.properties：

# Root logger option
log4j.rootLogger=INFO, file, stdout

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logging.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

这是我的 pom.xml:

**UPDATE : **

当我使用 WinRar 打开 jar 时，它显示它包含 log4j.properties 和 log4j jar，所以这不是资源问题！

Answer 1

检查您在maven 构建中的资源目录。应该是这样的。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
.......
     <build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
            </resource>
        </resources>
     </build>
</project>

这样 log4j.properties 文件将位于类路径目录中。

Answer 2

首先：它调用了：log4j.properties 而不是 Log4j.properties！

第二个：而不是 PropertyConfigurator.configure("log4j.properties"); 应该是：PropertyConfigurator.configure(getClass().getResource("/log4j.properties"));

将 log4j.properties 放在 Maven 项目中的什么位置？

Where to put log4j.properties in a maven project?

java

log4j

jar

maven

runnable-jar
