Log4j在随机时间/使用后停止工作

Question

我很难接受这样的信息：

15:34:47,323信息标准输出 log4j:终结名为consoleAppender的附录。

在我的项目工作了大约一个小时之后，在Eclipse控制台上愉快地查看了我的应用程序日志，这条消息就会出现，控制台仍然是空的。

我找不到原因:这个项目运行在Wildfly9上，jdk1.8 1.8。我的(最小) log4j.xml文件是相同的，这是为另一个项目工作！

<log4j:configuration debug="true" xmlns:log4j='http://jakarta.apache.org/log4j/'>

    <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
        <param name="target" value="System.out" />
        <param name="threshold" value="info" />
        <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>

    <logger name="org.hibernate">
        <level value="info" />
    </logger>

    <root>
        <appender-ref ref="consoleAppender" />
    </root>

</log4j:configuration>

我想有一些限制，在一定程度上“砍掉”我的原木。我的问题是:在哪里？

Answer 1

在您的pom.xml中，有slf4j-api和slf4j-log4j12。当部署到Wildfly时，您不需要它们，因为它增加了日志依赖的隐式性。您可以将slf4j-api设置为提供或排除Wildfly的日志库，如链接问题中所述。您还可以使用add-logging-api-dependencies禁用野生蝇日志库的自动添加，如在野生蝇的文档中中所述

Answer 2

我遇到了这个问题，当我试图寻找一个解决方案时，我在这里结束了。考虑到记录器可能持续几个小时或几分钟，并且需要重新启动才能恢复日志记录功能，这是非常恼人的。

原来这里提供的解决方案并没有帮助我，这就是为什么我要发布另一种解决方案。

对我来说最有效的是运行带有管理特权的"standalone.bat“。

在我从Windows 7“降级”到Windows 10 Build 1709之前，它并不是必需的。可以肯定地说，这个问题与操作系统有关，而不是Wildfly或Log4j实现。

我希望这能帮到别人！
