System.out.println无法打印到控制台

问题描述

我有一个在Wildfly 8. *上运行的Spring Web应用程序，由于某种原因，它不会打印到控制台上.我看到所有控制台日志和堆栈跟踪都很好，但是系统消息却没有出现.

I have a Spring web app running on Wildfly 8.* and for some reason it won't print to the console. I see all the console logs and stack traces fine but the System messages just don't appear.

问题可能出在我的log4j设置上，所以我将发布该配置.

The problem might be with my log4j setup so I'll post that config;

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration  PUBLIC
  "-//APACHE//DTD LOG4J 1.2//EN" "http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/doc-files/log4j.dtd">
<log4j:configuration debug="true"
    xmlns:log4j='http://jakarta.apache.org/log4j/'>

    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern"
          value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />
        </layout>
    </appender>

    <root>
        <level value="DEBUG" />
        <appender-ref ref="console" />
    </root>
</log4j:configuration>

我以前在JBoss 7.1上运行过应用程序，但是没有这个问题，所以我真的很茫然.

I've ran apps on JBoss 7.1 before however without this problem so I'm really at a loss on what could be wrong.

可以随时询问我的其他配置，不确定是否需要什么.

Feel free to ask about any of my other config not sure what would be needed.

logger.org.jboss.as.config.level=DEBUG
logger.org.jboss.as.config.useParentHandlers=true

logger.jacorb.config.level=ERROR
logger.jacorb.config.useParentHandlers=true

logger.org.apache.tomcat.util.modeler.level=WARN
logger.org.apache.tomcat.util.modeler.useParentHandlers=true

logger.com.arjuna.level=WARN

handler.CONSOLE=org.jboss.logmanager.handlers.ConsoleHandler
handler.CONSOLE.level=INFO
handler.CONSOLE.formatter=COLOR-PATTERN
handler.CONSOLE.properties=autoFlush,target,enabled
handler.CONSOLE.autoFlush=true

handler.FILE=org.jboss.logmanager.handlers.PeriodicRotatingFileHandler
handler.FILE.level=ALL

handler.FILE.append=true
handler.FILE.autoFlush=true
handler.FILE.enabled=true
handler.FILE.suffix=.yyyy-MM-dd
handler.FILE.fileName=C\:\\wildfly-8.2.0.Final\\standalone\\log\\server.log

formatter.PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.PATTERN.properties=pattern
formatter.PATTERN.pattern=%d{yyyy-MM-dd HH\:mm\:ss,SSS} %-5p [%c] (%t) %s%E%n

formatter.COLOR-PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.COLOR-PATTERN.properties=pattern
formatter.COLOR-PATTERN.pattern=%K{level}%d{HH\:mm\:ss,SSS} %-5p [%c] (%t) %s%E%n

这是我的独立部署文件夹中的日志记录配置.

Here is my logging config in my standalone deployments folder.

推荐答案

几年前，我在.war(WEB-INF/classes)的根目录下有一个log4j.properties文件，该文件引起了同样的问题-已修复删除它

I had a log4j.properties file at the root level of the .war (WEB-INF/classes) from years ago that caused the same issue - deletion fixed it
