Log4j2按模块名称分开的日志文件 [英] Log4j2 separate log files by module name

问题描述

我想根据模块名称编写日志文件. 对于前. 一个用于用户管理模块的日志文件，以及 一种用于产品模块等.

I want to write log files based on module name. for ex. one log file for user management module and one for products module etc.

我的项目包结构如下所示；

My project package structure looks like below;

com.mycompany.service.user
com.mycompany.service.product
com.mycompany.controller.user
com.mycompany.controller.product
...

我想写来自的日志消息 com.mycompany.*.user (com.mycompany.service.user和com.mycompany.controller.user)到com.mycompany.user.log文件， 和com.mycompany.*.product到com.mycompany.user.log文件.

I want to write log messages from com.mycompany.*.user (com.mycompany.service.user and com.mycompany.controller.user) to com.mycompany.user.log file, and com.mycompany.*.product to com.mycompany.user.log file.

我知道我可以创建像波纹管这样的记录器

I know I can create loggers like bellow

<logger name="com.mycompany.service.user" level="INFO">
  <AppenderRef ref="AppenderUsers" />
</logger>
<logger name="com.mycompany.controller.user" level="INFO">
  <AppenderRef ref="AppenderUsers" />
</logger>
...

但是通过这种方式，我必须添加许多记录器. 不能使用通配符*或**或正则表达式来记录这样的记录器名称吗?

But this way I have to add so many loggers. Cant I use wildcard * or ** or regex to logger name somethihng like this?

<logger name="com.mycompany.*.user" level="INFO">
  <AppenderRef ref="AppenderUsers" />
</logger>

或者有什么办法可以做到?

Or is there any way to do this?

推荐答案

最后，我已经通过编写自定义过滤器插件解决了这个问题. 我使用了 Regex 过滤器中使用的相同方法.但是正则表达式过滤器，将给定的正则表达式与Message内容匹配.但是我写了一个过滤器来匹配正则表达式和类名.

Finally I have solved this by writing a Custom Filter Plugin. I have used same approach used in Regex filter. But Regex filter, match given regex with Message content. But I have written a filter to match regex with class name.
