使用LogBack创建LOG_PATH_IS_UNDEFINED文件夹的SpringBoot
使用LogBack创建LOG_PATH_IS_UNDEFINED文件夹的SpringBoot
提问于 2014-08-12 04:36:51
我在LogBack中使用SpringBoot，并在yml文件中使用以下配置：
logging:
path: C:/var/log/pincode将logging.path Spring环境变量转移到LOG_PATH环境变量，并将日志文件放在正确的位置，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。
这似乎是由于SpringBoot使用其环境变量配置LogBack所使用的不同阶段造成的。

如果我从项目中删除我的logback.xml文件，它不会创建文件夹，所以在某个地方Spring在解析yml之前加载了xml？
如何避免登录以创建此LOG_PATH_IS_UNDEFINED目录？

在Spring Boot环境准备好之前，Spring Boot主类或SpringApplication将初始化记录器工厂，后者将检测默认配置文件(logback.groovy、logback.xml、logback-test.xml)，但此时Spring Boot应用程序尚未启动，这意味着变量LOG_PATH尚未设置。因此，首先您应该更改logback配置文件的名称，并在Spring Boot配置中将文件名手动配置为logging.config。通过这种方式，logback将在默认情况下配置一个控制台附加器，而不是创建一个文件附加器，然后当Spring Boot环境准备就绪时，它将触发一个enviromentready事件，这会导致LoggingApplicationListener重新配置logback。你可以在springboot的页面https://github.com/spring-projects/spring-boot/issues/2558上找到这个问题
