log4j2升级后出现的内部Grails日志

Question

我正在将grails 2.5.4应用程序中的log4j依赖项从1.2.17升级到最新版本2.17.1

我从BuildConfig.groovy中排除了log4j，并添加了与v2.17.1相关的以下依赖项：

• log4j api
• log4j核心
• log4j-1.2-api
• log4j-slf4j-impl

我用的是log4-1。x桥接以减少总体代码基更改。

我添加了以下log4j2。conf目录下的属性文件：

rootLogger.level = INFO
rootLogger.additivity = false
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %m%n

但在应用程序启动和使用期间，我注意到控制台中添加了额外的日志：

..........................................Attempting to load [0] user defined plugins
Grails plug-in [dataBinding] with version [2.5.4] loaded successfully
Grails plug-in [i18n] with version [2.5.4] loaded successfully

Grails plug-in [core] with version [2.5.4] loaded successfully

Grails plug-in [remotePagination] with version [0.4.8] loaded successfully
Grails plug-in [tomcat] with version [7.0.42] loaded successfully
...

一些Hibernate日志也出现了（由于存在域信息，所以没有添加日志）

看起来内部Grails日志被附加到控制台。在应用程序使用过程中，出现了以下类型的日志：

FrameworkServlet 'gsp': initialization started
GSP servlet initialized
FrameworkServlet 'gsp': initialization completed in 39 ms
Invocation of <r:resource> for a resource that apparently doesn't exist: /assets/favicon.ico
Invocation of <r:resource> for a resource that apparently doesn't exist: /assets/spinner.gif

Invocation of <r:resource> for a resource that apparently doesn't exist: /assets/spinner.gif
Invocation of <r:resource> for a resource that apparently doesn't exist: /assets/spinner.gif
...

似乎将additivity属性设置为false不起作用。我也尝试过使用添加剂，但没有成功。

我注意到Config.groovy中的log4j配置也没有被读取。

    log4j = {
  appenders {


    'null' name: 'empty'

    environments {
      development {
        'null' name: 'stacktrace'

        appender name: "appLog",
            new org.apache.log4j.DailyRollingFileAppender(
                threshold: org.apache.log4j.Level.INFO,
                datePattern: "'.'yyyy-MM-dd",
                file: "/tmp/test.log",
                layout: pattern(conversionPattern: '[%d{yyyy-MM-dd hh:mm:ss.SSS}] %p %c{5} %m%n'))
        root {
          info stdout
        }
      }

      production {
        file name: 'stacktrace', file: "/logs/stacktrace.log".toString()


        root {
          error 'stdout'
          info stdout
        }
      }

    }

  }

//  off 'ErrorsController & ResourceMeta'
  off 'org.grails.plugin.resource.ResourceMeta',
      'org.springframework.security.saml.metadata'

  error empty: ['grails.app.services.org.grails.plugin.resource',
                'grails.app.taglib.org.grails.plugin.resource',
                'grails.app.resourceMappers.org.grails.plugin.resource',
                'grails.app.resource.ResourceMeta']

  info 'grails.plugin.springsecurity.web.filter.DebugFilter'

  error 'org.codehaus.groovy.grails.web.servlet',  //  controllers
      'org.codehaus.groovy.grails.web.pages', //  GSP
      'org.codehaus.groovy.grails.web.sitemesh', //  layouts
      'org.codehaus.groovy.grails.web.mapping.filter', // URL mapping
      'org.codehaus.groovy.grails.web.mapping', // URL mapping

      'org.codehaus.groovy.grails.plugins', // plugins
      'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration
      'org.springframework',
      'org.hibernate'

  debug 'org.springframework.security.saml'

  warn 'org.mortbay.log'
  environments {
    development {
      //info additivity: true, appLog: "grails.app"
    }
  }


  root {
    additivity = false
  }
}

有人能指导我做错了什么吗？我如何阻止内部日志追加？

Answer 1

首先，在根记录器上指定相加性是没有意义的。请参阅Log4j 2配置-相加性了解相加性的工作原理。

开箱即用的Log4j 1不支持通过Groovy进行配置。据我所知，你们提供了一个基本的log4j 1。x配置，然后Groovy工具正在修改该配置。如果不看工具文档，我无法确定所有语法的含义。然而，很明显，这些线条

  error 'org.codehaus.groovy.grails.web.servlet',  //  controllers
  'org.codehaus.groovy.grails.web.pages', //  GSP
  'org.codehaus.groovy.grails.web.sitemesh', //  layouts
  'org.codehaus.groovy.grails.web.mapping.filter', // URL mapping
  'org.codehaus.groovy.grails.web.mapping', // URL mapping
  'org.codehaus.groovy.grails.commons', // core / classloading
  'org.codehaus.groovy.grails.plugins', // plugins
  'org.codehaus.groovy.grails.orm.hibernate', // hibernate integration
  'org.springframework',
  'org.hibernate'

在错误级别声明单个记录器。

因此，您需要在配置中添加行，例如

logger.hibernate.name = org.hibernate
logger.hibernate.level = error

以匹配Groovy代码的功能。如果不指定可加性，它将默认为true，消息将被路由到与根记录器关联的appender。
