java找不到commons日志记录类
真奇怪。我只是在我的web应用程序中更改了一些内容，但无法恢复这些内容，因为我记不起更改了什么
我在尝试运行我的Web应用程序时遇到此异常：

# 1 楼答案
第this页的选项2可能会对您有所帮助
（参见链接以获取POM代码段示例）
# 2 楼答案
我在pom中看到了commons日志的排除，异常还表示它找不到commons日志的jar。一定要检查一下
# 3 楼答案
看起来SpringWebMVC也依赖于commons日志。您应该为它添加一个排除项，就像您为SpringFramework和SpringSecurity所做的那样
# 4 楼答案
这似乎是一个IDE错误。。。我将Eclipse与WTP和Maven一起使用。有一个tmp0和tmp1文件夹，我重新创建了工作区。现在它又开始工作了。。。奇怪的问题
