已加载但未应用 log4j2.xml [JVM 参数]

本文介绍了已加载但未应用 log4j2.xml [JVM 参数]的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用 spring 批处理、spring mvc 和 spring boot 创建批处理.我正在使用 log4j2 进行日志记录.

I am trying to create a batch using spring batch, spring mvc and spring boot. And I am using log4j2 for logging.

我的目标是加载外部 log4j2.xml 配置文件，这要归功于 JVM 参数

My goal is to load an external log4j2.xml configuration file thanks to JVM arguments like that

-Dlog4j.configurationFile=file://C:\{path}\Workspace\demo-indexeur\config\log4j2.xml

Spring boot 检测我的文件(我在控制台中没有错误)并加载它但不应用我放在文件中的配置.

Spring boot detect my file (I have no error in the console) and load it but doesn't apply the configuration I put inside the file.

这里是我的配置文件加载的调试:

Here is the debug of the load of my configuration file :

当我将文件移动到src/main/resources"中时，它运行良好，但是当我尝试将文件外部化时却没有.

When I move the file inside "src/main/resources", it works perfectly but when I try to externalise the file it doesn't.

这是我的 xml 文件:

Here is my xml file :

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
  <Appenders>
    <Console name="Console" target="SYSTEM_OUT">
      <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
    </Console>
  </Appenders>
  <Loggers>
    <Root level="error">
      <AppenderRef ref="Console"/>
    </Root>
  </Loggers>
</Configuration>

这是我的依赖项:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-batch</artifactId>

    </dependency>

谁能告诉我为什么当我将文件外部化时它不起作用?感谢您的帮助.

Can someone tell me why it doesn't work when I externalize the file?Thank you for your help.

推荐答案

这就是为什么我的文件被检测和加载时没有错误，但没有被 spring boot 使用.

That 's why my file was detected and loaded without error but not used by spring boot.

我忘了告诉spring boot在哪里可以找到日志配置文件，为此，我必须在spring boot的application.properties中添加:

The thing I forgot is to tell spring boot where to find the logging configuration file too and for that, I have to add in the application.properties of spring boot :

logging.config= # location of logging config file

之后，一切正常.
