logback-spring.xml 配置springProfile时创建多个日志文件

Question

I am getting an issue while adding <springProfile> in my logback-spring.xml. In my case, I need to get the file name as well as path from the application.properties file and provide a date based rolling policy. So I can't specify the file name and path in logback-spring.xml.

So whenever I run the project specific to the profile from my IDE or by executable jar file, I am getting two log files created, one at the current working directory and the other at the specified file path location mentioned in the application.properties file.

I have three profiles based on the three different environments ie Local, Dev and Prod.

for local I am using spring OOTB application.properties file.

spring.profiles.active=local
server.port=8080

#logging 

logging.level.root=info
logging.level.com.myApp=trace
logging.file.path=C:/Spring/logs
logging.file.name=app-Log
logging.config=classpath:logback-spring.xml

and for dev and prod i am using application-dev.properties and application-prod.properties respectively.

application-dev.properties

spring.profiles.active=dev
server.port=9090

#logging 

logging.level.root=info
logging.level.com.myApp=trace
logging.file.path=C:/Spring/logs/dev
logging.file.name=app-Log
logging.config=classpath:logback-spring.xml

Here is my logback-spring.xml.

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

So after a long time I got to know the extra log file was created because of the property inside application.properties files.

The below property is honored by spring to create a file also I was mentioning the file name as well as the file path in the logback-spring.xml.

logging.file.name=app-Log

So whenever I run the application spring see this above property and creates the file in the current working directory and one other file in the specified location in the logback-spring.xml file.

${logging.file.path}/${logging.file.name}.log

So if you are mentioning the file name and path do not use the reserved words. I know its a very silly mistake but if it helps anyone then this will not be in vain.
