Question

我是Struts2的新手，我想在同一页面上验证两个表单标签：

userId行动

password

Login

在中心，我有另一个表单标签来注册新用户

现在我的问题是当我将addfielderror()应用于登录即（username和password字段）并填写注册表单时，新用户将没有userId和password登录。它显示登录表单标记的错误，该标记当时为空白。这种行为是错误的，反之亦然。所以，我该怎么做，当我正在登录时，它应该只检查登录操作，当我注册时应检查注册操作？

这是我Login行动的代码：

<s:form  method="Post" action="Login">
    <s:textfield   type="text" class=" input-small span2" name="login.Email"  placeholder="Email"></<s:textfield >
    <s:password type="password" class=" input-small span2" name="login.Pass"  placeholder="Password"></ s:password>
    <button type="submit" class="btn">Sign in</button> <br />      
</s:form>

这是注册码：

<s:form method="POST" action="Registor">
   <s:textfield class="span1" id="fname" name="FirstName" placeholder="First Name"></s:textfield>  
   <s:textfield class="span1" id="Lname" name="LastName" placeholder="Last Name"></s:textfield>  
   <s:password class="span2" id="password" placeholder="Password" name="Password"></s:password><br />       
   <s:textfield class="span2" id="email" placeholder="Email ID" name="Email_Id"></s:textfield>
   <br />
   <s:select headerKey="1" id="gender" headerValue="Select Gender" list="#@java.util.HashMap@{'Male':'Male','Female':'Female'}" name="Gender"></s:select><br />                   
   <button type="submit" id="submit" >Submit</button><br />                    
</s:form>

验证码

public void validate() {    
  //This is for login action            
  if((login.getPassword().equals("foobar")){
    addActionMessage(SUCCESS);  
  }else{
    addFieldError("Password", "Password should be greater then 6"); 
  }                         
  //This is for registration action              
  if((user.getPassword() == null) || (user.getPassword().length() < 6)){
    addFieldError("Password", "Password should be greater then 6"); 
  }       
}

现在，当我输入正确的密码时，"foobar"会在注册表单上显示错误

"Password should be greater then 6"

它应该显示登录操作的登录成功消息。

Struts.xml

<package name="default" extends="struts-default" >
    <action name="Login" class="org.register.customers.RegisterUserAction" method="getLogin">
        <result name="input">index.jsp</result>
        <result name="success">UserLoging.jsp</result>
        <result name="error">error.jsp</result>
    </action>
    <action name="Registor"  class="org.register.customers.RegisterUserAction" method="getRegistor">
        <result name="input">index.jsp</result>
        <result name="success">RegistorSuccess.jsp</result>
        <result name="error">index.jsp</result> 
    </action>
</package>

据我所知，您希望将两个不同操作的验证逻辑分开但您只有一个方法validate，并且两个操作映射到同一个操作类的方法。除了执行编程验证之外，您还应该使用验证拦截器来执行与执行操作相对应的validate方法的前缀方法调用。假设您的动作类扩展ActionSupport，因此您不必实现validate()方法也不必覆盖它。然后单独编写代码

 public void validateLogin() {    
   //This is for login action   
   if(login == null) {
     addActionError("Login is null"); 
   } else            
   if("foobar".equals(login.getPassword()){
     addActionMessage(SUCCESS); 
   } else {
     addFieldError("Password", "Password should be greater then 6"); 
   }   
 }   


 public void validateRegister() {
   //This is for registration action
   if(user == null) {  
     addActionError("User is null"); 
   } else            
   if(user.getPassword() == null || user.getPassword().length() < 6) {
     addFieldError("Password", "Password should be greater then 6"); 
   } 

 }
