打包后Play框架记录器未选择格式 [英] Play framework logger not picking format after packaging

问题描述

我已经格式化了使用conf文件夹中的logger.xml文件播放所生成的日志，以获取所需的格式.在我的本地环境中，当我使用普通播放命令(如play ~run或play -Dlogger.resource=logger.xml)启动时.但是，当我使用play dist打包并使用命令sudo ./start -Dlogger.resource=logger.xml开始该过程时，它将打印没有任何格式的默认日志.

I have formatted the logs generated by play using logger.xml file in conf folder to get the desired format. In my local environment when i am using the normal play commands like play ~run or play -Dlogger.resource=logger.xml start. But when i do packaging with play dist and start the process with command sudo ./start -Dlogger.resource=logger.xml it is printing default logs without any format.

logger.xml

<configuration>

  <conversionRule conversionWord="coloredLevel" converterClass="play.api.Logger$ColoredLevel" />

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
     <file>${application.home}/logs/application.log</file>
     <encoder>
       <pattern>%d{HH:mm:ss.SSS} [%level] %class:%method  %msg%n </pattern>
     </encoder>
   </appender>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%level] %class:%method  %msg%n </pattern>
    </encoder>
  </appender>

  <root level="ERROR">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="FILE" />
  </root>

  <logger name="application" level="debug" additivity="false">
    <appender-ref ref="STDOUT"/>
    <appender-ref ref="FILE"/>
  </logger>

</configuration>

推荐答案

您似乎正在使用Play 2.0.x-2.1.x，因为您使用的是play stage或play dist. 根据文档中的此部分，并假设您的logger.xml位于您的conf目录，则建议的文件正确配置为:

You seem to be using Play 2.0.x - 2.1.x based on the fact that you are using the start script generated by play stage or play dist. According to this section in the docs and assuming your logger.xml is in your conf directory, then the suggested correct config for your file would be:

sudo ./start -Dlogger.resource=logger.xml

但是，事实证明，如果您将Logback配置文件命名为logger.xml，则Play似乎会从类路径中选择默认的logger.xml配置文件，而不是您的.这可能就是为什么在文档中将配置文件的名称称为prod-logger.xml而不是logger.xml的原因，但是并没有对其进行明确说明.

However, it turns out that if you name your Logback config file logger.xml then Play seems to pick the default logger.xml config file from the classpath and not yours. Which is probably why the name of the config file in the docs is called prod-logger.xml and not just logger.xml, however that is not explicitly explained.

因此，将您的logger.xml文件重命名为其他名称.例如，test-logger.xml，然后以下内容将正确选择您的Logback配置:

So rename your logger.xml file to something else. For example test-logger.xml and then the following will correctly pick your Logback config:

sudo ./start -Dlogger.resource=test-logger.xml
