如何为Log4j启用jetty-maven-plugin 9

我跟随Jetty documentation用于独立的Jetty 9并添加了JAR和属性文件。

Jetty配置:

<plugin>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>9.0.5.v20130815</version>
    <configuration>
        <webApp>
            <contextPath>/mywebapp</contextPath>
            <jettyEnvXml>jetty-env.xml</jettyEnvXml>
        </webApp>
        <systemProperties>
            <systemProperty>
                <name>log4j.configuration</name>
                <value>log4j-jetty.properties</value>
            </systemProperty>
        </systemProperties>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.6.4</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.6.4</version>
        </dependency>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.16</version>
        </dependency>
    </dependencies>
</plugin>

使用Log4j在我的webb应用程序日志中弹出,但是Jetty仍然使用错误的记录器进行日志记录。

控制台输出:

我的Log4j属性:

log4j.rootLogger=info, stdout
log4j.debug=false

# console logger
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=<%d{ABSOLUTE}> <%-5p> <%c{1}> (%t) - %m%n

仅在pom.xml中设置日志属性的位置是不够的,它必须是命令行参数,请参阅Setting System Properties

  

但是,有时无法使用此功能设置系统属性 - 有时使用System属性的软件组件已经在maven运行时初始化(在这种情况下,您需要在命令行上提供System属性,或者在Jetty运行时提供。

更改了命令行:

mvn -Dlog4j.configuration=file:///D:/log4j-jetty.properties jetty:run

适用于Maven 3.0。

但它不适用于Maven 3.1,因为Maven 3.1包含SLF4J SimpleLogger,请参阅Maven 3.1.x logging

  

Maven 3.1.0以后的标准Maven发行版使用SLF4J API进行日志记录并结合SLF4J简单实现

和Jetty使用SLF4J Simple实现自己的日志(不是Web应用程序日志)而不是Log4j实现。
