Description

```

public void initLog(ServletContextEvent sce) throws Exception {
String logMerged = sce.getServletContext().getInitParameter("servicecomb.logging.merged");
if (!FALSE.toString().equalsIgnoreCase(logMerged))

{ Log4jUtils.init(); }

}

```

 

when run in servlet container, will init log4j, now log4j is removed for optional, user's need to init log4j themselves.
