Slf4j - enable debug,info messages

Question

I need to enable debug,info logs in a existing Java/spring-boot project.

This is the original application.properties file:

logging.level.org.springframework=WARN
logging.level.io.comp=INFO 

and this is the original logback.xml file:

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

<property name="LOGS_PATH" value="./logs" />

<appender name="ERROR_LOG_FILE"
          class="ch.qos.logback.core.rolling.RollingFileAppender">

<!-- Loggers -->

i tried to change the application.properties file to:

logging.level.org.springframework=DEBUG
logging.level.io.comp=DEBUG

and the logback.xml file to:

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

<property name="LOGS_PATH" value="./logs" />

</root>

<root level="INFO" >
    <appender-ref ref="INFO_LOG_FILE" />
    <appender-ref ref="DEBUG_LOG_FILE" />
</root>

but with no success. Only logs with levels: error,warn (log.error, log.warn) are printed to the the files.

What am I doing wrong?

Answer 1

I found the problem

Within the configuration of the project, reference was made to another properties file, in which the Logger level was WARN.
