问题描述

我正在尝试运行我的 struts 应用程序，但我收到错误操作未映射我已经看到命名空间是正确的，但仍然收到错误?

I am trying to run my struts application but I am getting a error action is not mapped I have seen the namespace it is correct but still getting the error?

struts.xml:

<?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.enable.DynamicMethodInvocation" value="false" />
    <constant name="struts.devMode" value="false" />

    <include file="register.xml"/>

    <!-- Add packages here -->

</struts>

还有我的register.xml:

<?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>

     <package name="register" namespace="/" extends="struts-default">

        <action name="Register" class="com.struts2.RegisterAction">
            <result name="input">/register.jsp</result>
            <result type="redirectAction">register.jsp</result>
        </action>

        <!-- Add actions here -->
    </package>
</struts>

我正在验证我的注册页面和验证 XML，如下所示

I am validating my register page and the validation XML as follows

RegisterAction-validation.xml:

<!DOCTYPE validators PUBLIC
        "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
        "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">

<validators>
    <field name="username">
        <field-validator type="requiredstring">
            <message key="requiredstring"/>
        </field-validator>
    </field>
    <field name="password">
        <field-validator type="requiredstring">
            <message key="requiredstring"/>
        </field-validator>
        <field-validator type="stringlength">
            <param name="minLength">6</param>
            <param name="trim">true</param>
            <message key="requiredpassword"/>
        </field-validator>
    </field>
    <field name="email">
        <field-validator type="requiredstring">
            <message key="requiredstring"/>
        </field-validator>
        <field-validator type="email">
            <message key="requiredemail"/>
        </field-validator>
    </field>
    <field name="gender">
        <field-validator type="requiredstring">
            <message key="requiredstring"/>
        </field-validator>
    </field>
    <field name="postalcode">
        <field-validator type="requiredstring">
            <message key="requiredstring"/>
        </field-validator>
        <field-validator type="regex">
            <param name="expression"><![CDATA[^d*$]]></param>
            <message key="requiredinteger"/>
        </field-validator>
    </field>
</validators>

而我的register.jsp如下:

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
    <title>Validation Struts page</title>
    <s:head/>
</head>

<body>
<s:form action="Register">
    <s:textfield key="username"/>
    <s:password key="password" />
    <s:textfield key="email" />
    <s:select headerKey="" headerValue="Select Gender"
     key="gender" list="#{'M':'Male','F':'Female'}" />
    <s:textfield key="postalcode" /> 
    <s:submit/>
</s:form>
</body>
</html>

我的项目结构如下:

Strutsvalidation
--src-->
    com.struts2(package)-->
      register.xml,
      registeraction-validation.xml,
      javaclasses,
      struts.xml
--webcontent-->
    web-inf-->
      web.xml
    register.jsp(in web content)

我收到如下错误?
