问题
我正在执行spring的简单依赖注入程序并获得此异常。我已经包含了common-logging1.1.1.jar和spring.jar文件。你能帮忙吗？

我也遇到了同样的问题，要修复，从下面的url下载jar文件
http://commons.apache.org/logging/download_logging.cgi
并复制到你的lib文件夹，将解决你的问题。

如果你使用maven来管理依赖项，请在pom.xml中添加以下行：
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.1</version>
</dependency>

你只需下载commons-logging-1.1.2.jar然后将此文件复制到libs
最后，它的工作原理。
