So confused on how to use Spring boot logging

I have a spring boot app which I am struggling to get logging working with a rolling appender strategy.

Here's the relevant part of my pom.xml

    org.springframework.boot
    spring-boot-starter-parent
    1.2.0.RELEASE
  

  
    
      org.springframework.boot
      spring-boot-starter-actuator
    
    
      org.springframework
      spring-jdbc
    
    
        phoenix
        phoenix
        4.1.0-client-hadoop2
    
    
      commons-dbcp
      commons-dbcp
      20030825.184428
    
    
      org.apache.directory.studio
      org.apache.commons.pool
      1.6
    
  

When I just run my app with the pom.xml left alone, I get this error:

java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError. See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details.

I read up on doing exclusions, so I figure I need to add the exclusion to the boot starter, like this:

  org.springframework.boot
  spring-boot-starter-actuator
  
    
        log4j-over-slf4j
        org.slf4j
    
  

Then when I run it, I get this other error:

java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/C:/maven/repo/phoenix/phoenix/4.1.0-client-hadoop2/phoenix-4.1.0-client-hadoop2.jar). If you are using Weblogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml Object of class [org.slf4j.impl.Log4jLoggerFactory] must be an instance of class ch.qos.logback.classic.LoggerContext

So it's talking about some conflict I guess with the phoenix driver but I don't understand why. When I load my pom.xml and look at the Dependency Heirarchy and look for that jar, it doesn't list anything under it that I can try to exclude.

So at this point I don't know how to proceed.

Solved

To remove logback do this:

        
            org.springframework.boot
            spring-boot-starter-actuator
            
                
                    log4j-over-slf4j
                    org.slf4j
                
                
                    logback-classic
                    ch.qos.logback
