未为操作com.ccarc.Contact定义结果，结果成功

问题描述 投票：0回答：5

我必须在这里丢失一些东西。我有以下struts.xml文件

<?xml version="1.0" encoding="UTF-8"?>
    <struts>
       <package name="myName" namespace="/myName" extends="struts-default">
        <action name="contact" class="com.ccarc.Contact">
           <result>/jsp/Contact.jsp</result>
           <result name="success">/jsp/Contact.jsp</result>
        </action>
   </package>
</struts>

我收到以下错误No result defined for action com.ccarc.Contact and result success

并且对于我的班级，我有以下内容（我删除了一些代码以使其更具可读性）

package com.ccarc;

import com.opensymphony.xwork2.ActionSupport;

public class Contact extends ActionSupport {

    public String execute() {
        System.out.println("in the action");

        return SUCCESS; // as defined by Action interface as "success"
    }
}

我环顾四周，但没有找到答案，大多数都是由忘记结果中名称的人问的（但您可以看到我列出了成功名称）

也是我的web.xml文件也在下面

<?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" id="WebApp_ID" version="3.0">

     <filter-name>struts2</filter-name>
     <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
     <init-param>

</filter>

  <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

[我还应该注意，我已经尝试将struts.xml中的类更改为“ Contact”，但仍然收到相同的错误消息。

我还验证了/WebConent/classes/com/ccarc/Contact.class的确存在。

另外，我应该在eclipse控制台中注意到，我看到了类的输出，因此正在调用该对象，但是当它从类返回时，就会出现问题。

编辑：

将您的URL更改为：

http://localhost:8080/FieldDayLogger/myName/contact.action

或者，如果要使用相同的URL，则在struts.xml中将名称空间更改为“ /”。

Here是了解名称空间配置和说明的好链接。 :)

原因之一是URLhttp://localhost:8080/FieldDayLogger/contact.action在您不使用URL的映射文件<package name="myName" namespace="/myName" extends="struts-default">中，您已将名称空间定义为/myName。

Struts2具有一种机制，通过它可以查找名称空间，如果找不到任何内容，它将转到默认名称空间，在您的情况下，它将找不到该名称空间。

命名空间不是像文件系统路径那样的分层结构。有一个名称空间级别。例如，如果请求URL /barspace/myspace/bar.action，则框架将首先查找名称空间/ barspace / myspace。如果/ barspace / myspace中不存在该操作，则搜索将立即退回到默认名称空间“”。框架不会将名称空间解析为一系列“文件夹”。在“命名空间示例”中，将选择默认命名空间中的bar操作。

我强烈建议您查看命名空间的文档并查看其工作原理

另一种解决方案是，如果要在from标记或其他此类标记中创建动作，则有一个属性，即namespace添加/myName。

希望这会对您有所帮助。

我想“接触”就像是Struts2中的关键词。请将com.ccarc.Contact重命名为com.ccarc.MyContact，然后重试...

最好总是使用命名空间。如果要访问的文件位于WebContent内，则可以使用namespace =“ /”命名，也可以根据文件的目录结构使用“ /”以外的任何名称。

尝试以下操作。

<package name="myName" namespace="/myName" extends="struts-default">
        <action name="contact" class="com.ccarc.Contact">
           <result name="success">jsp/Contact.jsp</result>
        </action>

我在tile.xml中缺少定义：

<tiles-definitions>

...

  <definition name="foobar" template="/jsp/template.jsp">
    <put-attribute name="viewId" value="foobar"/>
    <put-attribute name="workArea"  value="/jsp/foobar.jsp"/>
  </definition>

...

</tiles-definitions>
