日志不会显示调用方法或行号

Question

我已经为我开发的一个项目设置了日志记录，但我似乎无法获得要显示在日志中的行号和调用方法。我有一个 Maven 项目，maven-compiler-plugin 被配置为在编译的类中包含调试信息。

在日志中包含这些信息对我非常有帮助，并且让我了解为什么现在没有发生这种情况。谁能帮我解释一下这里发生了什么以及如何在我的日志中获取方法名称和行号？

这是我的 pom：

这是我的 log4j2.xml 配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration
    status="debug"
    monitorInterval="600">

    <Appenders>
        <Console
            name="CONSOLE"
            target="SYSTEM_OUT">
            <PatternLayout
                pattern="%d [%4.4t] [%5.5p] %35.35c(%15.15M):%-5.5L - %m%n" />
        </Console>
        <File
            name="EDIFY-NUANCE"
            fileName="../logs/n2e-ws.log">
            <!--<PatternLayout

             <PatternLayout pattern="%d %5p %20.30c [%t] %20.30C (%F:%L) %m%n"

        </File>
        <Async name="ASYNC">
            <AppenderRef ref="EDIFY-NUANCE" />
            <AppenderRef ref="CONSOLE" />
        </Async>
    </Appenders>

    <Loggers>
        <logger
            name="log4j.logger.httpclient.wire.header"
            level="fatal"
            additivity="false" />
        <Root level="debug">
            <AppenderRef ref="ASYNC" />
        </Root>
    </Loggers>
</Configuration>

Answer 1

您需要在配置中为异步记录器或异步附加器指定includeLocation="true"。另见http://logging.apache.org/log4j/2.x/manual/async.html#Location 和http://logging.apache.org/log4j/2.x/manual/appenders.html#AsyncAppender

顺便说一句，您的配置有一个没有 AppenderRef 的记录器（名称为“log4j.logger.httpclient.wire.header”）。那是行不通的。

因此，将它们放在一起，您的配置应该如下所示：

<Appenders>
    ...
    <Async name="ASYNC" includeLocation="true">
        <AppenderRef ref="EDIFY-NUANCE" />
        <AppenderRef ref="CONSOLE" />
    </Async>
</Appenders>
<Loggers>
    <Logger name="log4j.logger.httpclient.wire.header"
            level="fatal" additivity="false">
      <AppenderRef ref="ASYNC" />
    </Logger>
    <Root level="debug">
        <AppenderRef ref="ASYNC" />
    </Root>
</Loggers>
