struts.xml中：

<?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="getLogin" class="login.action.LoginAction"  
            method="login">
            <result name="success">/Profile.jsp</result>
            <result name="input">/LoginError.jsp</result>
        </action>

        <action name="getRegistered" class="login.action.LoginAction"
            method="register">
            <result name="success">/Success.jsp</result>
            <result name="input">/login.jsp</result>
        </action>

    </package>
</struts>

我试图将此XML中的两个Action映射到Action类

中的两个不同方法

LoginAction.java：

package login.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;
import com.opensymphony.xwork2.ActionSupport;
import login.service.LoginDao;
import login.service.RegisterDao;

@SuppressWarnings("serial")
public class LoginAction extends ActionSupport implements ServletRequestAware,
        ServletResponseAware {

    private String username;
    private String password;
    private HttpServletRequest httpServletRequest;
    private String firstname;
    private String lastname;
    private String regpassword;
    private String conpassword;
    private String regemail;
    private String conemail;
    private String phone;

    public String register(){
        RegisterDao rdao = new RegisterDao();
        String registered = rdao.registerdao(firstname,lastname,regpassword,conpassword,regemail,conemail,phone);
        if(registered == "TRUE"){
            return SUCCESS;
        }

        return INPUT;
    }


    public String login() {
        System.out.println("user name::: "+username);
        httpServletRequest.getSession().setAttribute("key", username);
        httpServletRequest.getSession().setAttribute("key", password);
        LoginDao db = new LoginDao();
        Boolean validate = db.loginresult(username, password);
        if (validate == true) {
            return SUCCESS;

        } else {
            return INPUT;
        }
    }

    public HttpServletRequest getHttpServletRequest() {
        return httpServletRequest;
    }

    public void setHttpServletRequest(HttpServletRequest httpServletRequest) {
        this.httpServletRequest = httpServletRequest;
    }

    public String getFirstname() {
        return firstname;
    }

    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }

    public String getLastname() {
        return lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    public String getRegpassword() {
        return regpassword;
    }

    public void setRegpassword(String regpassword) {
        this.regpassword = regpassword;
    }

    public String getConpassword() {
        return conpassword;
    }

    public void setConpassword(String conpassword) {
        this.conpassword = conpassword;
    }

    public String getRegemail() {
        return regemail;
    }

    public void setRegemail(String regemail) {
        this.regemail = regemail;
    }

    public String getConemail() {
        return conemail;
    }

    public void setConemail(String conemail) {
        this.conemail = conemail;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public void setServletRequest(HttpServletRequest request) {
        this.httpServletRequest = request;

    }


    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;
    }

    @Override
    public void setServletResponse(HttpServletResponse arg0) {
        // TODO Auto-generated method stub

    }



}

使用登录和注册方法的Action类：

**login.jsp**
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <center>
        <%@ taglib uri="/struts-tags" prefix="s"%>
        <s:form action="getLogin.action" method="post" validate="true">
            <s:textfield label="Name"  key="username"/>
            <s:password label="Password" key="password"/>
            <s:checkbox name="Rememberme" label="Remember Me" value="yes"
                checked="checked"/>
            <s:submit value="Sign in"/>
        </s:form>
    </center>
</body>
</html>

Login.jsp，它重定向到Action类中的login方法。早些时候它工作正常。现在这个动作给出了麻烦：

**Registration.jsp**

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <center>
        <%@ taglib uri="/struts-tags" prefix="s"%>
        <s:form action="getRegistered.action" method="post" validate="true">
            <div>
                <table>
                    <s:textfield label="First Name" key="firstname" />
                    <s:textfield label="Last Name" key="lastname" />
                    <s:password label="Create your password" key="regpassword" />
                    <s:password label="Confirm your password" key="conpassword" />
                    <s:textfield label="Email" key="regemail1" />
                    <s:textfield label="Re-Type Email" key="conemail" />
                    <s:textfield label="Phone" key="phone" />   
                    <tr>
                    <td><s:submit value="Register" theme="simple"/></td>
                    <td><s:submit value="Cancel" theme="simple" onclick="document.forms[0].action='login.jsp';" /></td>
                    </tr>
                </table>
            </div>
        </s:form>
    </center>
</body>
</html>

Registration.jsp重定向到getRegistered操作：

**LoginAction-Validation.xml**

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN"  
    "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">

        </field-validator>
    </field>
    <!-- Login page validation ends -->

验证xml登录用户名和密码..

当我运行此代码时，它始终返回＆＃34; INPUT＆＃34;在登录操作的情况下字符串并重定向到LoginError.jsp，在寄存器操作的情况下重定向到login.jsp。请建议我如何在不使用validation.excludeMethods

的情况下解决此问题

的LoginAction-getRegistered-validation.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN"  
    "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
<validators>
<!-- Registration validation Starts -->
    <field name="firstname">
        <field-validator type="requiredstring">
            <param name="trim">true</param>
            <message>Firstname is mandatory</message>
        </field-validator>
        <field-validator type="stringlength">
            <param name="minLength">5</param>
            <param name="maxLength">10</param>
            <param name="trim">true</param>
            <message>First Name must be between 5 to 10 characters long</message>
        </field-validator>
    </field>
    <field name="lastname">
        <field-validator type="requiredstring">
            <param name="trim">true</param>
            <message>Lastname is mandatory</message>
        </field-validator>
        <field-validator type="stringlength">
            <param name="minLength">5</param>
            <param name="maxLength">10</param>
            <param name="trim">true</param>
            <message>Last Name must be between 5 to 10 characters long</message>
        </field-validator>
    </field>
    <!-- Registration validation ends -->
</validators>

我已对第一个和最后一个名称进行了验证

2 个答案:

答案 0 :(得分：0)

从.action中的操作名称中删除<s:form>扩展名，并确保在部署时将{mm}复制到WEB-INF/classes下。

<s:form action="getRegistered" method="post" validate="true">

更简洁的方法是使用<s:url>并在<s:form>中引用创建的网址。

<s:url var="actionUrl" action="getRegistered" namespace="" />
<s:form action="%{actionUrl}" method="post" validate="true">

答案 1 :(得分：0)

在每个类的验证文件中，因此它验证此类中由validation拦截器拦截的所有操作/方法。您应该为第一个操作getLogin（例如LoginAction-getLogin-validation.xml）分隔验证逻辑，并为getRegistered操作定义另一个验证文件，例如LoginAction-getRegistered-validation.xml。它们将按行动处理。此外，regex验证程序的参数为regex，而不是expression。

<field-validator type="regex">
  <param name="regex"><![CDATA[((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%]).{5,10})]]></param>
  <message>Password must </message>
</field-validator>
