为什么点击登入按钮的时候没反应，麻烦大家给看看...谢谢！

Answer 1

<form action="login.action" method="post">
姓名:<input type="text" name="username"><br>
密码:<input type="text" name="password"><br>
<input type="submit" value="点击登录">

</form>
表单写错了 是form不是from 点击按钮没反应 不是submit写错 就是 form写错了 再就死浏览器的关系 后者可能性不大

Answer 2

看到一个很明显的问题LoginAction为什么没有继承ActionSupport，不继承ActionSupport怎么让struts2帮你做事那？

public class LoginAction extends ActionSupport

加上后在试试吧

form也写错了

Answer 3

这个问题<result name="loginsuc">/loginsuc.jsp</result>
<result name="loginfail">/loginfail.jsp</result>
出现了不在这里的结果，所以没有反应，这个问题是初学的时候常常都要犯的

Answer 4

<form>拼错了...
你写成<from>了。
