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

问题描述

在我的application.yml中，我得到了:

In my application.yml I got:

logging: 
  config: classpath:log4j2.debug.yml

还有其他一些位于不同配置文件中的文件.当我启动该应用程序时，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放在已分析的文件旁边，则它可以工作.所以我认为这是我错过依赖关系的原因，或者使用log4j2无法实现?

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:启动日志记录级别说应该可以像我尝试的那样?

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，另一个用于记录文件.因此，我制作了两个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.

我使用两个Spring配置文件:默认一个和一个名为"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，该文件会自动激活.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，只需在application.properties中将"dev"添加为"spring.profiles.active ="的值即可.

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

您可以在此页面上查看周飞宇的回答.他提出了使用Yaml配置文件的解决方案:如何通过以下方式定义log4j2路径是application.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，您始终可以删除application.properties的属性logging.config并在log4j2.xml中重命名log4j2-file.xml.默认情况下，它将由Log4j2加载，而无需由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
