首先，如果您不希望用户认为他们的名字有扩展名，您应该摆脱行动扩展。

First of all you should get rid of action extension, if you don't want user to think their name has an extension.

<constant name="struts.action.extension" value=",,action"/> 

接下来模式匹配器应为 regex 。

Next the pattern matcher should be regex.

<constant name="struts.patternMatcher" value="regex"/>

行动映射

<action name="/CustomURL/{username}" class="com.rajesh.struts2.CustomURL" method="customUrl">
    <result name="success">welcome.jsp</result>
</action>

在JSP中，您不需要使用表单标签，但锚标签。并使用已知名称。

In the JSP you don't need to use form tag, but anchor tag. And use known names.

<a href="http://localhost:8080/CustomURL/rajesh">Click my name</a>
