为什么不能去掉log4j

helloZy_90 2012-12-13 02:15:36
拷贝的别人的项目，里面配置了log4j，我不需要打印日志，想把log4j移除掉。
我把log4j的配置文件删除了，相关的jar包也删除了，启动tomcat还是报这个错，
大神帮忙看下是不是还有哪里没删完

你删掉了包，删掉了配置文件，既然有用到Log，那么在代码里面肯定有调用这个log的。 所以，会报错说找不到logFactory的类。因为配置文件以及包都删掉了啊，删掉代码中的log调用吧

有可能Log4j是其它jar包的依赖包，这样你就不能删除了

你把log4j的配置文件删除了，但是配置信息里肯定还在的，还会调用到该配置文件的吧，说明日志文件spring或者其他的合成配置的，你要找到相关的配置信息删掉，或者代码里有调用的话，在代码里也得删掉，要是还抱错的话，我建议你还是保留日志文件吧，有日志也没啥不好的。或者日志的配置文件都不删，只删掉代码里的，这些是我的建议，修改别人的代码是件非常痛苦的事情，祝愿楼主尽快完成任务吧！

恩，貌似jar包多删了吧，先把jar包都考回来，看看还报错吗
全部的jar包里面有slf4j，我不需要这个

这个不是log4j,是commons-logging的包，是不同的
我把commons-logging包拷进去了，还是有这个错：nested exception is java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory 我现在完全不需要这个功能
