带有LogBack的SpringBoot创建LOG_PATH_IS_UNDEFINED文件夹

本文介绍了带有LogBack的SpringBoot创建LOG_PATH_IS_UNDEFINED文件夹的处理方法，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

我将SpringBoot与LogBack一起使用，并在yml文件中使用以下配置:

I am using SpringBoot with LogBack and using the below configuration in my yml file:

logging:
    path: C:/var/log/pincode

logging.path Spring环境变量被转移到LOG_PATH环境变量，并且日志文件被放置在正确的位置，但是在我的项目的根目录中也创建了一个名为LOG_PATH_IS_UNDEFINED的目录.

The logging.path Spring Environment Variable is transferred to the LOG_PATH Environment variable and the log file is placed at the correct place, but there is also a directory called LOG_PATH_IS_UNDEFINED created in the root directory of my project.

这似乎是由于SpringBoot使用其环境变量配置LogBack所用的阶段不同.

This seems to be caused by the different phase used by SpringBoot to configure LogBack with its Environment variables.

17:29:21,325 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Assuming default type [ch.qos.logback.classic.encoder.PatternLayoutEncoder] for [encoder] property

...
17:29:21,358 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - End of configuration.

然后，它再次开始配置登录，但是这次使用我设置的路径:

And then after that it start configuring logback again but this time using the path i set:

如果我从项目中删除logback.xml文件，则不会创建该文件夹，因此在解析yml之前Spring正在加载xml?

If I remove my logback.xml file from the project it doesn't create the folder, so somewhere Spring is loading the xml before parsing the yml?

如何避免使用Logback创建此LOG_PATH_IS_UNDEFINED目录?

How can I avoid Logback to create this LOG_PATH_IS_UNDEFINED directory?

推荐答案

在您的情况下，LOG_PATH在启动时未定义.您应该改用${LOG_PATH:-.}，请参见.

In your case LOG_PATH is not defined on startup. You should use ${LOG_PATH:-.} instead , See .

但是，如果在application.properties中定义logging.path，您将在.和${logging.path}目录中看到两个日志文件.

But if you define logging.path in your application.properties you will see two log files in . and in ${logging.path} directory.

Logback初始化后设置Spring容器LOG_PATH ...据我所知，不支持Logback惰性文件创建.在这种情况下，您应该使用logback-spring.xml代替logback.xml.

Spring container set LOG_PATH after Logback initialization... Logback is not supported lazy file creation as far as I know. In this case you should use logback-spring.xml instead logback.xml.
