Struts驗證用戶名和密碼不起作用

[英]Struts validation username and password not working

 原文  2014-03-05 09:26:44  9   1    java/ validation/ struts-1

問題描述

我正在使用struts1並使用用戶名和密碼進行驗證。請參見以下代碼

register.jsp 

    <%@taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
    <%@taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
    <%@taglib uri="http://struts.apache.org/tags-logic" prefix="logic"%>

<bean:message key="my.title" />

<html:form action="register" method="GET">

    <bean:message key="my.un" />                    
    <html:text property="userName"></html:text>
    <html:errors property="userName" />

    <br>

    <bean:message key="my.pwd" />
    <html:text property="password"></html:text>
    <html:errors property="password" />

    <br>

    <html:submit>
        <bean:message key="my.btn.cap" />
    </html:submit>

</html:form>

<logic:notEmpty name="msg" scope="request" >
    <bean:write name="msg" scope="request" />
</logic:notEmpty>

RegisterForm.java 

package com.rajeev.form;
import org.apache.struts.validator.ValidatorForm;

public class RegisterForm extends ValidatorForm {
    String userName,password;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

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

RegisterAction.java 

package com.rajeev.action;


import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.rajeev.form.RegisterForm;

public class RegisterAction extends Action {

    public RegisterAction() {
        System.out.println("RegisterAction const");
    }

    @Override
    public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception {

        System.out.println("in execute method");
        RegisterForm registerForm = (RegisterForm) form;

        String userName = registerForm.getUserName();
        String password = registerForm.getPassword();

        if (userName.equals("Rajeev") && password.equals("java")) {
            request.setAttribute("msg", "valid");
            return mapping.findForward("result");
        } else {
            request.setAttribute("msg", "invalid");
            return mapping.findForward("result");
        }

    }
}

validation.xml中 

<?xml version="1.0" encoding="iso-8859-1"?>

<!DOCTYPE form-validation PUBLIC
          "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.3.0//EN"
          "http://jakarta.apache.org/commons/dtds/validator_1_3_0.dtd">
<form-validation>

    <formset>

        <form name="rf">
            <field property="userName" depends="required">
                <arg key="my.un" position="0" />
            </field>
            <field property="password" depends="required">
                <arg key="my.pwd" position="0" />
            </field>
        </form>
    </formset>

</form-validation>

struts-config.xml中 

<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
          "http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
    <form-beans>
        <form-bean name="rf" type="com.rajeev.form.RegisterForm"></form-bean>
    </form-beans>
    <action-mappings>
        <action path="/register" name="rf" scope="request"
            type="com.rajeev.action.RegisterAction" input="/register.jsp">
            <forward name="result" path="/register.jsp"></forward>
        </action>
    </action-mappings>

    <message-resources parameter="myFile"></message-resources>

    <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
        <set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validator-rules.xml" />
    </plug-in>
</struts-config>

myFile.properties 

#presentation labels
my.un=UserName
my.pwd=Password

my.btn.cap=Login
my.title=<h1>login page</h1>

#default error message
errors.userName.required={0}is required.

我還附加了工作區中的validateator-rules.xml文件。上面的程序無需驗證即可正常工作。我編寫了用戶名和密碼（要求用戶名和密碼）的驗證碼，如果有人單擊登錄而未在其中輸入用戶名和密碼文本框。有人幫我為什么它不起作用。

在此處輸入圖片說明

如下更改您的struts-config.xml 

<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
          "http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
    <form-beans>
        <form-bean
            name="rf"
            type="com.rajeev.form.RegisterForm"
        ></form-bean>
    </form-beans>
    <action-mappings>
        <action
            path="/register"
            name="rf"
            scope="request"
            type="com.rajeev.action.RegisterAction"
            input="/register.jsp"
        >
            <forward
                name="result"
                path="/register.jsp"
            ></forward>
        </action>
    </action-mappings>
    <message-resources parameter="myFile"></message-resources>
     <plug-in className="org.apache.struts.validator.ValidatorPlugIn" >
    <set-property property="pathnames"
    value="/WEB-INF/validator-rules.xml, /WEB-INF/validation.xml"/>

   </plug-in>
</struts-config>

然后是validation.xml，如下所示 

   <?xml version="1.0" encoding="iso-8859-1"?>

<!DOCTYPE form-validation PUBLIC
          "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.3.0//EN"
          "http://jakarta.apache.org/commons/dtds/validator_1_3_0.dtd">
<form-validation>

    <formset>

        <form name="rf">
            <field property="userName" depends="required">
                <arg key="my.un" position="0" />
                <msg name="required" key="errors.userName.required"/>
            </field>
            <field property="password" depends="required">
                <arg key="my.pwd" position="0" />
                 <msg name="required" key="errors.userName.required"/>
            </field>
        </form>
    </formset>

</form-validation>

並運行..
