java Spring Maven项目CommonLogging LogFactory NoClassDefFoundError
我有一个Maven项目，它使用Spring运行json web服务。该项目在NetBeans中运行良好。它被编译成一个jar文件，jar文件在Ubuntu虚拟机中运行良好。但是，当我尝试在Windows中运行jar文件时，我得到了以下错误
java-jarmyjar。jar——服务器。端口=8000

我花了一整天的时间想弄明白这一点，但没有结果
有人能解释一下吗

# 1 楼答案
在
commons-logging依赖项中包括以下内容：这是一条防止
commons-logging包含在jar中的指令。因此它不在类路径上# 2 楼答案
Spring框架使用Apache Commons日志API进行日志记录。 在SpringBoot父POM中，有一个对Commons日志库的明确排除
这意味着您可以在运行时为Spring类提供一个选定的Commons日志实现
您可以将commons日志添加到POM中，最新版本为1.2，于2014年7月发布
或者您可以使用jcl-over-SLF4J将Apache Commons日志API连接到SLF4J API（请参见http://www.slf4j.org/legacy.html）。jar，然后添加您选择的SLF4L实现。例如：
