SLF4J+Logback不登录WildFly

Question

我在wildfly8中运行web应用程序，但由于某些原因，它没有登录。我使用SLF4J与日志。日志文件是在部署时创建的，但它是空的。我在wildfly日志中也看不到我的日志语句。

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");

null

<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>

在我看来,LOGBACK配置成功。但日志消息会丢失。知道那里会发生什么吗？这让我毫无意义。

WildFly将slf4j添加为默认日志依赖项，如果您尝试将主实现排除在jboss-deployment-structure.xml描述符中（它应该在META-INF目录下）。这可以通过以下行来实现：

<?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>
