Cause: the commons-logging.jar package is missing

Solution:

① Add maven dependency:

<dependency>
    <groupId>commons-logging</groupId>
    <artifactId>commons-logging</artifactId>
    <version>1.2</version>
</dependency>

Download jar package: http://files.cnblogs.com/files/hujinshui/commons-logging-1.2.zip
