SLF4J + Logback不会登录WildFly [英] SLF4J + Logback does not log in WildFly

问题描述

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。我没有在wildfly日志中看到我的日志语句。

I run web application in WildFly 8 and for some reason it does not log. I use SLF4J with LOGBACK. The log file is created on deploy but it is empty. I do not see my log statements in wildfly logs either.

该类包含：

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; \\ slf4j-api-1.7.5.jar


• WEB-INF \lib \ logback-classic-1.1.1.jar


• WEB-INF\lib\logback-core-1.1.1.jar


• WEB-INF\classes\logback.xml

• WEB-INF\lib\slf4j-api-1.7.5.jar
• WEB-INF\lib\logback-classic-1.1.1.jar
• WEB-INF\lib\logback-core-1.1.1.jar
• WEB-INF\classes\logback.xml

配置文件logback.xml包含：

Configuration file logback.xml contains:

<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：

console.log contains logback initialization:

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？这让我毫无意义。

It seems to me that LOGBACK is successfully configured. But log messages are lost. Any idea what is going there? It makes me no sense.

推荐答案

WildFly将slf4j添加为默认日志记录依赖项您是否尝试排除中的主要实现jboss-deployment-structure.xml 描述符（它应该在META-INF目录下）。这可以通过以下几行完成：

WildFly adds slf4j as a default logging dependency Have you tried excluding the main implementation in jboss-deployment-structure.xml descriptor (It should go under the META-INF directory). This can be done with below lines:

<?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>
