You still have to add common-logging dependency under your classpath. However, you may continue encounter other simaliar Exceptions due to lack other dependency. I suggest you use maven to manage the dependency so that you don't have to mannualy add dependencies to your classpath.
您仍然必须在类路径下添加common-logging依赖项。但是,由于缺乏其他依赖性,您可能会继续遇到其他simaliar异常。我建议您使用maven来管理依赖项,这样您就不必手动将依赖项添加到类路径中。

It seems your project doesn't contain the Apache Commons Logging library. Adding it to your classpath should do the trick.
您的项目似乎不包含Apache Commons Logging库。将它添加到类路径应该可以解决问题。

This is caused by the missing of commons-logging.jar.To fix it, download the commons logging library and add it to your project.
这是由于缺少commons-logging.jar引起的。要修复它,请下载commons日志库并将其添加到项目中。
