The remove(String,String)method was added to version 2.1 of commons-lang. It is not present in 2.0 and earlier.
该remove(String,String)方法已添加到 commons-lang 2.1 版中。它在 2.0 及更早版本中不存在。
Depending on which Servlet Container or Application Server you use (and which version of it), the server class path may contain an outdated version of commons-lang, which is used instead of your copy of commons-lang in the applications /lib folder. If that's your problem, you can configure your application to prefer the application class path, instead of the server class path.
根据您使用的 Servlet 容器或应用程序服务器（以及它的哪个版本），服务器类路径可能包含一个过时的 commons-lang 版本，它用于代替您在应用程序 /lib 文件夹中的 commons-lang 副本。如果这是您的问题，您可以将应用程序配置为更喜欢应用程序类路径，而不是服务器类路径。

Because as far as I can see in javadoc StringUtils has method remove that accepts 2 string arguments and does not have one that accepts 3 arguments:
因为据我在 javadoc StringUtils 中看到的方法 remove 接受 2 个字符串参数并且没有接受 3 个参数的方法：
public static String remove(String str,
String remove)
see http://commons.apache.org/lang/api-2.5/org/apache/commons/lang/StringUtils.html
见http://commons.apache.org/lang/api-2.5/org/apache/commons/lang/StringUtils.html
Since there are different versions of StringUtils double check that your are working with the same version in development and deployment environment.
由于有不同版本的 StringUtils，请仔细检查您在开发和部署环境中是否使用相同的版本。
