javaweb项目，用的log4j的日志框架，如下LogFactory生成的日志，为啥在文件中不打印呢？

Question

private static Log logger = LogFactory.getLog(Compl_GdInfoAction.class);//org.apache.commons.logging.LogFactory

logger.info("1")//日志中不打印
private static Logger log = Logger.getLogger(Form_AddAppInfoAction.class);//org.apache.log4j.Logger

log.info("2")//日志中可以打印

Answer 1

先确定你的commons-logging底层用的是不是log4j吧
