Question

目前我是struts 2的新手，但我知道但是当我尝试在struts中执行验证时，我在struts 2示例中遇到问题，这是一个自定义验证示例。所有代码如下：

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";  
}  
}

struts.xml中

<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>

请检查代码，并在此验证示例中告诉我我在哪里犯了错误。

感谢所有能帮助我的人......

Answer 1

我遇到同样的问题我解决了这个错误：

您需要在index.jsp文件中进行一次更改。在表单中更改操作。（逐个尝试两个表格线）

<%@ 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>

我希望它能解决你的问题。

Answer 2

尝试

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

分开进入

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

Answer 3

我认为这可行。更改您的struts.xml代码

<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>

到

<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>

只需更改结果序列。首先定义success，然后定义input

Answer 4

检查你的web.xml。你的web.xml有以下过滤器？

<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>

Answer 5

好吧，我想你知道struts是如何工作的，你已经做了一切正确但仍然无法找出你的项目有什么问题。您已正确提及您的操作类名称，方法名称正确。结果页面设置正确但仍然失败。我有一件事你应该检查。例如，如果您从网页和动作类中获取名称和年龄，则将名称设置为字符串，将age设置为int作为同一类的成员变量或以模型驱动的方式。在用于测试目的的网页中，您输入了名称和年龄的字符。在这种情况下，struts将检查action字符串，该字符串将字符串作为名称和年龄但无法找到它。因为您创建的操作类将name作为字符串，将age作为int。因此抛出404错误。

或者你可以试试这个。

我发现更改输入有助于解决此问题。我从一开始就通过适当刷新来启动我的Web应用程序，它似乎解决了这个问题。

Answer 6

变化

<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>

到

<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>

Answer 7

改变这个 -

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

到

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

Struts.xml文件中的

由于

为什么我在Struts 2应用程序中没有为动作定义结果
