在Maven Jetty 7插件中启用调试日志记录

更新: 好吧,我终于把事情做好了,我就是这么做的。

我的理解是,Jetty7不依赖于特定的日志框架,即使对于JSP引擎也是如此,因为Jetty7使用JSP 2.1引擎。所以您可以使用任何日志框架。在这里我将使用logback。

第一次添加 logback-classic 作为插件中的依赖项并设置 logback.configurationFile 指向配置文件的系统属性:

<project>
  ...
  <build>
    ...
    <plugins>
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>7.0.0.pre5</version>
        <configuration>
          <systemProperties>
            <systemProperty>
              <name>logback.configurationFile</name>
              <value>./src/etc/logback.xml</value>
            </systemProperty>
          </systemProperties>
        </configuration>
        <dependencies>
          <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>0.9.15</version>
          </dependency>
        </dependencies>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

然后添加一个 src/etc/logback.xml 配置文件。最低配置以下:

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <layout class="ch.qos.logback.classic.PatternLayout">
      <Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</Pattern>
    </layout>
  </appender>

  <root level="debug">
    <appender-ref ref="STDOUT"/>
  </root>
</configuration>

通过此设置,Jetty将输出调试消息:

$ mvn jetty:run
...
00:31:33.089 [main] DEBUG org.mortbay.log - starting DefaultHandler@145e5a6
00:31:33.089 [main] DEBUG org.mortbay.log - started DefaultHandler@145e5a6

00:31:33.217 [main] DEBUG org.mortbay.log - started org.mortbay.jetty.Server@a010ba

• 这个 Chapter 3: Logback configuration 从日志文件

要扩展Pascal的答案,以下是它与log4j的工作方式:

<project>
  ...
  <build>
    ...
    <plugins>
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>7.0.0.pre5</version>
        <configuration>
          <systemProperties>
            <systemProperty>
              <name>log4j.configurationFile</name>
              <value>file:${project.basedir}/src/test/resources/log4j.properties</value>
            </systemProperty>
          </systemProperties>
        </configuration>
        <dependencies>
           <dependency>
             <groupId>log4j</groupId>
             <artifactId>log4j</artifactId>
             <version>1.2.16</version>
           </dependency>
           <dependency>
             <groupId>org.slf4j</groupId>
             <artifactId>slf4j-api</artifactId>
             <version>1.6.1</version>
           </dependency>
           <dependency>
             <groupId>org.slf4j</groupId>
             <artifactId>slf4j-log4j12</artifactId>
             <version>1.6.1</version>
           </dependency>
        </dependencies>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

这是你的 ${project.basedir}/src/test/resources/log4j.properties :

log4j.rootLogger=INFO, CONSOLE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern = [%-5p] %c: %m\n
log4j.logger.org.eclipse.jetty.util.log=INFO

其他资源:

• Jetty Log configuration
• log4j configuration

您也可以这样做“mvn-x jetty:run”

要扩展Pascal和Yegor256的答案,这就是它的工作原理 SLF4J Simple logger (这是最简单的选择,因为您只需要向 slf4j-simple ):

<project>
  ...
  <build>
    ...
    <plugins>
      <plugin>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jetty-maven-plugin</artifactId>
        <version>7.0.0.pre5</version>

        <dependencies>
           <dependency>
              <groupId>org.slf4j</groupId>
              <artifactId>slf4j-simple</artifactId>
              <version>1.7.5</version>
           </dependency>
        </dependencies>
      </plugin>
      ...
    </plugins>
  </build>
  ...
</project>

可以直接从maven pom配置slf4j记录器。默认值在 http://www.slf4j.org/apidocs/org/slf4j/impl/SimpleLogger.html )

例如,登录到一个文件 /tmp/output.log 具有更高的调试级别( TRACE ):

<configuration>
   <systemProperties>
      <systemProperty>
         <name>org.slf4j.simpleLogger.logFile</name>
         <value>/tmp/output.log</value>
      </systemProperty>
      <systemProperty>
         <name>org.slf4j.simpleLogger.defaultLogLevel</name>
         <value>trace</value>
      </systemProperty>
   </systemProperties>
</configuration>

我觉得这个解决方案更方便

    <resources>
        <resource>
            <directory>${project.basedir}/src/main/resources</directory>
            <targetPath>${project.build.outputDirectory}</targetPath>
            <includes>
                <include>log4j.properties</include>
            </includes>
        </resource>
    </resources>

也不要忘记粘贴

    <overwrite>true</overwrite>
