Do you have Apache Commons Codec in your Classpath?
你的类路径中有 Apache Commons Codec 吗？
If you are using maven, include it with this snippet:
如果您使用的是 maven，请将其包含在以下代码段中：
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.10</version>
</dependency>
Or just drop the .jar from hereinto your classpath.
或者只是将.jar 从这里放到你的类路径中。

This error could raise wether from not importing:
此错误可能会因不导入而引发：
import org.apache.commons.*;
Or from not declaring previously any of the variables you are using here.
或者之前没有声明您在此处使用的任何变量。
