Enabling logs in Spring boot cloud foundry application

Question

how do i enable spring framework logs in my application. ? i have used logback.xml in my application and set the root level to debug. When i am trying to run the app locally then logs are printed but the same is not happening when i am deploying the application in CF. The application itself is crashing due to other reason but i hoped some initial spring boot framework logging should have happened.

Below is my logback.xml file. I am not sure the console appender mentioned there will work in CF system too or not.`

 <?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
            </Pattern>
        </layout>
    </appender> 

<root level="TRACE">
<appender-ref ref="STDOUT" />
    </root>
</configuration>

Best Regards,

May be this was a problem with the spring boot CF service broker application which was causing the logs to not be printed. Check here CF Spring boot app failed to start accepting connections

But then i deleted the application and redeployed again. It started printing logs. The above configuration works.
