I think you can use MDC to change logging level programmatically. The code below is an example to change logging level on current thread. This approach does not create dependency to logback implementation (SLF4J API contains MDC).

  
    LOG_LEVEL
    DEBUG
    
      TRACE
      TRACE
    
    
      DEBUG
      DEBUG
    
    
      INFO
      INFO
    
    
      WARN
      WARN
    
    
      ERROR
      ERROR
    
  
  ......

MDC.put("LOG_LEVEL", "INFO");
