我们最近将struts从2.2.1升级到2.3.34。升级后，验证框架无法正常工作。获得以下例外。

重新启动tomcat服务器时发生异常。验证框架在旧版本中运行良好。请帮助解决此问题。
答案 0 :(得分：0)
试试这个PUBLIC ID：
<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
答案 1 :(得分：0)
找到解决方案!!!
我们正在使用classname-method-validation.xml文件和validators.xml文件。
在classname-method-validation.xml中，提供如下文档类型：
<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN"
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
并在validators.xml中，使用以下doc类型：
<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator Definition 1.0//EN"
"http://struts.apache.org/dtds/xwork-validator-definition-1.0.dtd">
此外，在使用正则表达式进行验证时，我们将param名称用作expression。它应该更改为regexExpression。
例如：
<field-validator type="regex" short-circuit="true">
<param name="regexExpression"><![CDATA[^(?!0{9})(\d{9})$]]>
</param>
<message>${getText("ft.accounts.alert.validRoutingNumber")}</message></field-validator>
