SLF4J + Logback不会登录WildFly

Question

我在WildFly 8中运行Web应用程序,由于某种原因它不会记录.我使用SLF4J和LOGBACK.日志文件是在部署时创建的,但它是空的.我也没有在wildfly日志中看到我的日志语句.

该课程包含:

package com.blah.oops;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

static final Logger log = LoggerFactory.getLogger(EndpointImpl.class);

log.debug("request called");

战争包含:

• WEB-INF\lib中\ SLF4J-API-1.7.5.jar
• WEB-INF\lib中\的logback经典-1.1.1.jar
• WEB-INF\lib中\的logback核-1.1.1.jar
• WEB-INF \类\ logback.xml

配置文件logback.xml包含:

<configuration scan="true" scanPeriod="10 seconds">
    <appender name="FILE" class="ch.qos.logback.core.FileAppender">
        <file>${LOG_PATH}/backend-main.log</file>
        <encoder>
            <pattern>%date %level [%thread] %logger{10} %msg%n</pattern>
        </encoder>
    </appender>

    <!-- PROFILER configuration -->
    <turboFilter class="ch.qos.logback.classic.turbo.MarkerFilter">
        <Marker>PROFILER</Marker>
        <OnMatch>ACCEPT</OnMatch>
        <!--  <OnMatch>DENY</OnMatch> -->
    </turboFilter>

    <logger name="org.eclipse.jetty.util.log" level="info"/>
    <logger name="com.blah" level="debug"/>
    <logger name="org.apache.cxf" level="warn"/>

    <root level="info">
        <appender-ref ref="FILE"/>
    </root>
</configuration>

console.log包含logback初始化:

在我看来,LOGBACK已成功配置.但是日志消息丢失了.知道发生了什么吗？这让我没有意义.

Answer 1

WildFly将slf4j添加为默认日志记录依赖项您是否尝试在jboss-deployment-structure.xml描述符中排除主要实现(它应该位于META-INF目录下).这可以通过以下方式完成:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
  <deployment>
    <exclusions>
      <module name="org.apache.commons.logging" />
      <module name="org.apache.log4j" />
      <module name="org.jboss.logging" />
      <module name="org.jboss.logging.jul-to-slf4j-stub" />
      <module name="org.jboss.logmanager" />
      <module name="org.jboss.logmanager.log4j" />
      <module name="org.slf4j" />
      <module name="org.slf4j.impl" />
    </exclusions>
  </deployment>
</jboss-deployment-structure>

Answer 2

Wildfly使用slf4j作为defult日志记录.你必须告诉jboss不要使用slf4j,我正在使用log4j.你可以使用下面的jboss-deployment-structure.xml来做到这一点

<jboss-deployment-structure>
  <deployment>
     <!-- exclude-subsystem prevents a subsystems deployment unit processors running on a deployment -->
     <!-- which gives basically the same effect as removing the subsystem, but it only affects single deployment -->
     <exclude-subsystems>
        <subsystem name="logging" />
    </exclude-subsystems>
  </deployment>
</jboss-deployment-structure>
