获取java.lang.ClassNotFoundException：org.apache.commons.logging.LogFactory异常

Question

我正在执行spring的简单Dependency Injection程序并获取此异常。我已经包含了common-logging1.1.1.jar和spring.jar文件。你能帮忙吗？

如果你正在使用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>
