struts2 action找不到404

Question

刚学习struts2，做到登录功能的时候登录按钮点击之后就显示action404的页面
我的工程结构是这样的

web.xml

 <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>ieZhan</display-name>
  <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
    </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <welcome-file-list>  
    <welcome-file>index.jsp</welcome-file>  
  </welcome-file-list>  
</web-app>

struts.xml

<package name="struts2" extends="struts-default" namespace="/">
      <action name="login" class="com.login.struts2.loginAction">
          <result name="success" type="redirect">/aboutus.jsp</result>
          <result name="failer" type="redirect">/contactus.jsp</result>    
      </action>
</package>

jsp页面中的form代码

 <s:form action="login" >
            <ul class="login_cont">
                <li class="f14">会员登录</li>
                <li class="login_ipt"><p><span class="fl tr">账号：</span><input type="text" class="login_txt fl" name="username"/></p></li>
                <li class="login_ipt"><p><span class="fl tr">密码：</span><input type="password" class="login_txt fl" name="password"/></p></li>
                <li><a href="#" class="fr">忘记登录密码？</a><label><input type="checkbox" class="remember_psw" />记住密码</label></li>
                <li class="mt10"><button class="login_button login_button_signup" type="submit" >登录</button></li>
            </ul>
            </s:form>

我看了下在页面上的action的url是

我试过加namespace=“/” 路径变成/ieZhan/login 也不行
希望有好心人帮忙解决下。

Answer 1

在页面上面加上
<%  
String path = request.getContextPath();  
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";  
%> 

form的  action里面写
action="<%=basePath%>login"
