<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

   "http://struts.apache.org/dtds/struts-2.0.dtd">

 <struts-config>
    <package name="default" extends="struts-default">

Answer 1

看起来您没有为struts应用程序定义名称空间。

基本配置可能如下所示。

<package name="default">
    <action name="foo" class="mypackage.simpleAction">
        <result name="success" type="dispatcher">greeting.jsp</result>
    </action>

    <action name="bar" class="mypackage.simpleAction">
        <result name="success" type="dispatcher">bar1.jsp</result>
    </action>
</package>

<package name="mypackage1" namespace="/">
    <action name="moo" class="mypackage.simpleAction">
        <result name="success" type="dispatcher">moo.jsp</result>
    </action>
</package>

<package name="mypackage2" namespace="/barspace">
    <action name="bar" class="mypackage.simpleAction">
        <result name="success" type="dispatcher">bar2.jsp</result>
    </action>
</package>

namespace="/"定义要查找的默认命名空间。

Struts配置文件中有错误的标记。它应该是<struts>。并且文件的名称应为struts.xml。此文件应位于类路径上，即WEB-INF/classes文件夹中。还应该有一个动作类。

<?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="default" extends="struts-default">
        <action name="getTutorial" class="org.tutorial.action.StrutsAction">
           <result name="success">/success.jsp</result>
           <result name="error">/failure.jsp</result>
        </action>
    </package>
</struts>

没有针对命名空间[/]映射的Action和与上下文路径关联的操作名称
