格式化slf4j以使用颜色记录消息类型 [英] Formatting slf4j to log message types with colors

问题描述

我正在使用slf4j登录我的Java应用程序.它涉及大量的日志记录和日志监视.
当整个日志以黑色打印时，有时真的很难从日志中读取和查找信息.
只是为了使其更具可读性，是否可以用不同的颜色记录不同类型的消息?
例如，所有红色或不同字体大小的错误级别消息，以及所有蓝色和不同字体大小的信息级别消息.

I am using slf4j for logging in my Java Application. It involves a lot logging and log monitoring.
Sometimes it is really difficult to read and find information from logs when the entire log is printed in the black color with.
Just to make it more readable, is it possible to log the different kinds of messages in different colors?
For example all Error level messages in Red color or a different font size and all Info level messages in blue color and a different font size.

欢迎提出任何建议或帮助. 谢谢.

Any suggestions or help is welcome. Thnx.

推荐答案

我想到了两个解决方案.它们不是颜色，而是替代解决方案:

Two solutions come to my mind. They are not colors, but alternative solutions:

1. 在File Appender配置中，您可以配置模式以包括日志级别(错误，警告等).然后，您可以grep文件，以按级别过滤消息.

1. In your File Appender configuration, you can configure the pattern to include the log level (error, warn, etc). Then you can grep the file, to filter messages by level.

您可以配置两个具有不同级别阈值的文件追加器(用于两个单独的日志文件).例如，一个会将所有高于调试级别的日志(因此，info，warn，error)记录到logs.txt中，而另一个仅将错误日志记录到errors.txt中.

You can configure two file appenders (for two separate log files) with different level threshold. For instance, one would log all the logs above debug level (so info, warn, error) into let's say logs.txt and the other would log only the errors logs into errors.txt
