log4j 2向控制台appender添加多种颜色 [英] log4j 2 adding multiple colors to console appender

问题描述

您好我刚刚下载并配置了log4j-2。我坚持将颜色代码应用于 SlowConsole 控制台appender。我的控制台appender如下所示。

Hi I just downloaded and configured log4j-2. I am stuck on applying color codes to the SlowConsole console appender. My console appender is like below.

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %logger{36} - %msg%n"/>
        </Console>
        <Console name="SlowConsole" target="SYSTEM_OUT">
            <PatternLayout pattern="%highlight{%d{HH:mm:ss.SSS} %-5level %logger{36}.%M() @%L - %msg%n}{FATAL=red, ERROR=red, WARN=yellow, INFO=black, DEBUG=green, TRACE=blue}"/>
        </Console>
        <File name="File" fileName="C:\log\out.txt">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %logger{36} - %msg%n" />
        </File>
    </Appenders>
    <Loggers>
        <logger name="org.abc.ea.web" level="ALL" additivity="false">
            <!--Log4j for the WEB MODULE -->
            <appender-ref ref="SlowConsole"/>
        </logger>
        <logger name="org.abc.ea.ejb" level="ALL" additivity="false">
            <!--Log4j for the EJB MODULE -->
            <appender-ref ref="SlowConsole"/>
        </logger>
        <Root level="ERROR">
            <AppenderRef ref="Console"/>
            <AppenderRef ref="File" />
        </Root>
    </Loggers>
</Configuration>

我有两个问题，

1. 我是log4j的新手，这是编写xml配置文件的正确方法吗？

1. I am new to log4j, is this the right way to write xml config file?

如何添加两种颜色代码到每个日志级别？

How can i add two color codes to each log level?

例如：DEBUG = green - >将输出浅绿色字体，但我需要它 dim 和粗体

for example: DEBUG=green -> will output light green font, But i need it to be dim and bold

推荐答案

我想我找到了解决方案。我下载了log4j2-core-sources.jar并追踪了来源。你可以写如下;

I think I found the solution. I downloaded log4j2-core-sources.jar and traced the source. You can write it as below;

<Console name="SlowConsole" target="SYSTEM_OUT">
     <PatternLayout pattern="%highlight{%d{HH:mm:ss.SSS} %-5level %logger{36}.%M() @%L - %msg%n}{FATAL=red blink, ERROR=red, WARN=yellow bold, INFO=black, DEBUG=green bold, TRACE=blue}"/>
</Console>

我认为log4j2 文档及其示例可能需要更新。

I think log4j2 documentation and its examples may need to be updated.
