Spring Profiles，不同的 Log4j2 配置 [英] Spring Profiles, different Log4j2 configs

问题描述

在我的 application.yml 中我得到:

In my application.yml I got:

logging: 
  config: classpath:log4j2.debug.yml

还有其他一些在不同的配置文件中.当我启动应用程序时，我得到以下信息:

And some others in different profiles. When I start the Application I get the following:

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.

如果我只是将 log4j2.xml 放在配置文件旁边，它就可以工作.所以我认为这是我错过依赖的地方，或者 log4j2 不可能?

If I just put log4j2.xml next to the profiled ones it works. So I think this is a something where I miss a dependancy or it is not possible with log4j2?

参考:启动日志级别 说应该可以，就像我尝试的那样?

Reference: Boot Logging Level says it should be possible like I try?

推荐答案

在我这边，我使用的是属性文件而不是 yaml 文件.我想要两个日志文件:一个将所有内容记录到控制台，另一个记录在一个文件中.所以我做了两个log4j2配置文件:log4j2-dev.xml和log4j2-file.xml.

On my side, I am using properties file instead of a yaml one. I wanted two log files: one which logs everything to the console, and another one which logs in a file. So I made two log4j2 configuration files: log4j2-dev.xml and log4j2-file.xml.

我使用了两个 Spring 配置文件:默认的一个和一个名为dev"的配置文件.为了切换 log4j2 配置文件，我创建了一个文件 application.properties，其中包含:

I use two Spring profile: the default one and one named "dev". To switch the log4j2 configuration file, I created a file application.properties containing:

spring.profiles.active=
logging.config=classpath:log4j2-file.xml

我还有另一个属性文件 application-dev.properties，当 Spring 检测到dev"配置文件时，它会自动激活.它包含:

And I have another properties file, application-dev.properties, which is activated automatically when Spring detects the "dev" profile. It contains:

logging.config=classpath:log4j2-dev.xml

当我想使用 log4j2-dev.xml 配置时，我只需在 application.properties 中添加dev"作为spring.profiles.active="的值.

When I want to use the log4j2-dev.xml configuration, I just add "dev" as value of "spring.profiles.active=" in application.properties.

您可以在此页面查看周飞宇的回答.他提出了一个使用 Yaml 配置文件的解决方案:How to define log4j2 path byapplication.properties?

You can take a look to the Feiyu Zhou's answer at this page. He present a solution using a Yaml configuration file: How to define log4j2 path by application.properties?

当然，您可以随时删除 application.properties 的属性 logging.config 并在 log4j2.xml 中重命名 log4j2-file.xml.它将默认由 Log4j2 加载，无需由 Spring 配置文件触发

Of course, you could always remove the attribute logging.config of application.properties and rename log4j2-file.xml in log4j2.xml. It will be loaded by default by Log4j2 without the need to be triggered by a Spring profile
