Question

我正在使用Liferay6和Struts2。

这是LOgin.jsp

<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Struts 2 Login Application!</title>
</head>
<body>
<s:form action="login" method="POST" validate="true">
<tr>
<td colspan="2">
Login
</td>
</tr>
<s:actionerror />
<s:fielderror />
<s:textfield name="username" label="Login name"/>
<s:password name="password" label="Password"/>
<s:submit value="Login" align="center"/>
</s:form>
</body>
</html>

这是struts.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <constant name="struts.devMode" value="true" />

    <package name="default" extends="struts-default" namespace="/view">
         <action name="login"
            class="net.LoginAction">
            <result name="success">/Welcome.jsp</result>
            <result name="error">/view.jsp</result>
        </action>
    </package>
</struts>

这是异常堆栈跟踪

Answer 1

There is no Action mapped for action name default.

但您的操作名称登录

<action name="login" class="net.LoginAction">

您的操作网址必须为sitename/youapp/view/login.action

另外还要记录你的hava两个动作。

    <action name="prepareLogin" class="net.LoginAction" method="input">
        <result name="success">/login.jsp</result>
    </action>

prepareLogin - 此操作仅查看登录页面

    <action name="login" class="net.LoginAction"  method="execute">
        <result name="success">/Welcome.jsp</result>
        <result name="error">/login.jsp</result>
    </action>

login - 此操作获取记录

Liferay + Struts2没有为动作名称默认映射的动作。
