为Jetty的Maven插件配置日志记录? [英] Configure logging for Jetty's maven plugin?

问题描述

我正在通过以下插件配置调用"jetty:run"目标:

I'm invoking the "jetty:run" goal with the following plugin configuration:

<plugin>
  <groupId>org.mortbay.jetty</groupId>
  <artifactId>jetty-maven-plugin</artifactId>
  <version>7.4.4.v20110707</version>
  <configuration>
    <scanIntervalSeconds>5</scanIntervalSeconds>
    <connectors>
      <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
        <port>80</port>
      </connector>
    </connectors>        
  </configuration>
</plugin>

尽管我的项目将slf4j声明为依赖项，但Jetty拒绝将任何内容记录到slf4j.如果我将"-Dorg.eclipse.jetty.util.log.DEBUG = true"传递给JVM，Jetty将输出大量日志，但它们似乎是输入stderr而不是slf4j.有什么想法吗?

Jetty refuses to log anything to slf4j in spite of the fact that my project declares slf4j as a dependency. If I pass "-Dorg.eclipse.jetty.util.log.DEBUG=true" to the JVM, Jetty outputs tons of logs but they seem to go to stderr instead of to slf4j. Any ideas?

推荐答案

回答我自己的问题:

1. 插件看不到项目依赖项.您需要在<plugin>中指定<dependencies>.

您需要指定一个具体的slf4j实现，例如logback.指定slf4j是不够的.

You need to specify a concrete slf4j implementation, such as logback. Specifying slf4j is not enough.

最终结果应如下所示:

  <plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>7.4.4.v20110707</version>
    <configuration>
      <scanIntervalSeconds>5</scanIntervalSeconds>
      <connectors>
        <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
          <port>80</port>
        </connector>
      </connectors>        
    </configuration>
    <dependencies>
      <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>0.9.29</version>
      </dependency>
    </dependencies>
  </plugin>
