You need to install bridges to SLF4J from whatever logging implementations are in use by your third-party libraries.

See http://www.slf4j.org/legacy.html

Subject: [logback-user] Turn the log of android spring to debug

Hi all,

I have a Android project which is using logback+slf4j. I am able to get the logs of the my classes, which have slf4j loggers. But is it possible to enable the debug log for the 3-party library. Specifically, I want to turn the log of android spring to debug. I tried the configuration as below but it does not work:

<appender name="file" class="ch.qos.logback.core.FileAppender">

    <file>/data/data/com.example/files/log/foo.log</file>

    <encoder>

      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>

    </encoder>

  </appender>

    <logger name="org.springframework" level="DEBUG" additivity="false">

<appender-ref ref="file" />

   </logger>

Any advice?
