我已经尝试了很多东西，但是当我单击HR表单的提交按钮时无法解决错误404的问题。我需要在提交HR表单后立即重定向到output.jsp页面。有人可以帮忙吗？

使用struts标签。
通过在开头添加它来加载它们：
<%@ taglib prefix="s" uri="/struts-tags" %>
像这样使用它们：
<s:form action="output" method="post">
<s:textfield key="username" label="HR id:" />
<s:textfield key="password" label="Psswd:" />
<s:submit type="button">login</s:submit>
</s:form>
通过切换/更改struts ui主题并使用css来改变布局。
