為什么我在Struts 2應用程序中沒有定義要采取行動的結果

[英]Why am I getting No result defined for action in Struts 2 application

問題描述

目前，我是Struts 2的新手，但是我有知識，但是當我嘗試在Struts中執行驗證時，我在自己的Struts 2示例中遇到了問題，這是一個自定義驗證示例。 所有代碼如下：

的index.jsp 

  <%-- 
    Document   : index
    Created on : Jan 9, 2014, 10:58:52 AM
    Author     : manoj.sharma
--%>

<%@ taglib uri="/struts-tags" prefix="s" %>  
<s:form action="register">  
    <s:textfield name="name" label="Name"></s:textfield>  
    <s:password name="password" label="Password"></s:password>  
    <s:submit value="register"></s:submit>  
</s:form>

的welcome.jsp 

    <%-- 
    Document   : welcome
    Created on : Jan 9, 2014, 11:08:37 AM
    Author     : manoj.sharma
--%>

<%@ taglib uri="/struts-tags" prefix="s" %>  
Name:<s:property value="name"/><br/>  
Password:<s:property value="password"/><br/>

RegisterAction.java 

/*

 */

package com.org.my.action;
import com.opensymphony.xwork2.ActionSupport;
/**
 *
 * @author manoj.sharma
 */
public class RegisterAction extends ActionSupport{  
private String name,password;

    //getters and setters 
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

public void validate() {  
    if(name.length()<1)  
        addFieldError("name","Name can't be blank");  
    if(password.length()<6)  
        addFieldError("password","Password must be greater than 5");  
}  

public String execute(){  
//perform business logic here  
    return "success";  
}  
}

在struts.xml 

<struts>
    <!-- Configuration for the default package. -->
    <package name="default" extends="struts-default">
        <action name="register" class="com.org.my.action.RegisterAction">  
            <result name="input">/index.jsp</result>
            <result name="success">/welcome.jsp</result>
        </action>  
    </package>
</struts>

請檢查代碼，並讓我知道在此驗證示例中我在哪里出錯。

Tomcat控制台錯誤：

我有同樣的問題，我解決了這個錯誤：

您需要在index.jsp文件中進行一項更改。 更改表單中的操作。 （一一嘗試兩條表格線） 

<%@ taglib uri="/struts-tags" prefix="s" %>  
    <s:form action="RegisterAction.action">  or  <s:form action="register.action"> 
        <s:textfield name="name" label="Name"></s:textfield>  
        <s:password name="password" label="Password"></s:password>  
        <s:submit value="register"></s:submit>  
    </s:form>

希望它能解決您的問題。

嘗試 

public class RegisterAction extends ActionSupport{  
    private String name,password;

分成 

public class RegisterAction extends ActionSupport{  
    private String name;
    private String password;

我認為這可能有效。 更改您的struts.xml代碼 

<struts>
<!-- Configuration for the default package. -->
<package name="default" extends="struts-default">
    <action name="register" class="com.org.my.action.RegisterAction">  
        <result name="input">/index.jsp</result>
        <result name="success">/welcome.jsp</result>
    </action>  
</package>

至 

<struts>
<!-- Configuration for the default package. -->
<package name="default" extends="struts-default">
    <action name="register" class="com.org.my.action.RegisterAction">  
        <result name="success">/welcome.jsp</result>
        <result name="input">/index.jsp</result>
    </action>  
</package>

只需更改結果的順序即可。首先定義success ，然后input

檢查您的web.xml。 您的web.xml具有以下過濾器？ 

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>
    <listener>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

好吧，我想您知道struts是如何工作的，並且您已完成所有正確的操作，但是仍然無法找出項目的問題所在。 您的動作類名稱正確提及，方法名稱正確。 結果頁面設置正確，但仍然失敗。 我有一件事你應該檢查。 例如，如果要從網頁和操作類中獲取名稱和年齡，則可以將名稱設置為字符串，將年齡設置為int作為同一類的成員變量或以模型驅動方式設置。 在用於測試目的的網頁中，您需要輸入姓名和年齡。 在這種情況下，struts將檢查動作類，該類將字符串作為名稱和年齡，但找不到它。 因為您創建的操作類將名稱作為字符串，將年齡作為int。 因此，將引發404錯誤。

或者您可以嘗試一下。

我發現更改輸入有助於解決此問題。 我從一開始就通過適當刷新來啟動Web應用程序，它似乎可以解決問題。

更改 

<struts>
<!-- Configuration for the default package. -->
<package name="default" extends="struts-default">
    <action name="register" class="com.org.my.action.RegisterAction">  
        <result name="input">/index.jsp</result>
        <result name="success">/welcome.jsp</result>
    </action>  
</package>
</struts>

至 

<struts>
<!-- Configuration for the default package. -->
<package name="default" namespace="/" extends="struts-default">
    <action name="register" class="com.org.my.action.RegisterAction">  
        <result name="input">/index.jsp</result>
        <result name="success">/welcome.jsp</result>
    </action>  
</package>
</struts>

改變這個- 

<action name="register" class="com.org.my.action.RegisterAction">

至 

 <action name="register" class="com.org.my.action.RegisterAction" method="execute">

在您的Struts.xml文件中

謝謝
