LOGBACK: No context given for c.q.l.core.rolling.SizeAndTimeBasedRollingPolicy@1162810564

Question

I get the error on the title: LOGBACK: No context given for c.q.l.core.rolling.SizeAndTimeBasedRollingPolicy@1162810564

I get it with spring boot application's latest version after I added: logging.file.name =src/main/resources/logs/spring advance.log to the application.properties which is working fine I just can not understand why and what does Logback mean and if this is an error/warning? and how to fix it?

If I do not save the log to log file and only print it on the console I do not get this error

This is my full application.properties:

spring.datasource.url=jdbc:mysql://localhost:3306/example? 
createDatabaseIfNotExist=true&serverTimezone=IST
spring.datasource.username=root
spring.datasource.password=1234
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

Answer 1

Added logback-spring.xml in resources folder fixed the issue for me. The content of the XML file can be found at https://docs.spring.io/spring-boot/docs/1.5.x/reference/html/howto-logging.html.

Answer 2

you should include xml config file and point to it in your application.properties

logging.config=classpath:config/logback-spring.xml

and here is the config file i used:

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