请告诉我以下是我的设置可以做什么。

  <action path="/Postaddd" 
            type="bseller.postadd.PostaddAction" 
            parameter="dispatch"
            scope="request"
            validate="true"
            input="/SubmitPost.jsp"
            name="PostadddForm">
        <forward name="posterror" path="ordererror.page"/>
        <forward name="successPost" path="bseller.successPost.page"/>  

    </action>


public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) 
    {


        Logger  log= Logger.getLogger("BSELLER_APPLICATION");
        log.info("validate method called");
        ActionErrors errors = new ActionErrors();

          log.info("Email Id: " + getEmailid()); 
          if(!Validation.isValidEmailAddress(getEmailid()))
                  {
              errors.add("emailid", new ActionMessage("prompt.email.error"));
                  }
          if(!Validation.isPhoneNumberValid(getMobile()))
          {
              errors.add("mobile", new ActionMessage("prompt.contactno.error"));
          }

          if(!Validation.isNumeric(getPrice()))
          {
              errors.add("price", new ActionMessage("prompt.price.error"));
          }


        return errors;
    }
原文

Please tell me what I can do following are my settings.

  <action path="/Postaddd" 
            type="bseller.postadd.PostaddAction" 
            parameter="dispatch"
            scope="request"
            validate="true"
            input="/SubmitPost.jsp"
            name="PostadddForm">
        <forward name="posterror" path="ordererror.page"/>
        <forward name="successPost" path="bseller.successPost.page"/>  

    </action>


public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) 
    {


        Logger  log= Logger.getLogger("BSELLER_APPLICATION");
        log.info("validate method called");
        ActionErrors errors = new ActionErrors();

          log.info("Email Id: " + getEmailid()); 
          if(!Validation.isValidEmailAddress(getEmailid()))
                  {
              errors.add("emailid", new ActionMessage("prompt.email.error"));
                  }
          if(!Validation.isPhoneNumberValid(getMobile()))
          {
              errors.add("mobile", new ActionMessage("prompt.contactno.error"));
          }

          if(!Validation.isNumeric(getPrice()))
          {
              errors.add("price", new ActionMessage("prompt.price.error"));
          }


        return errors;

我刚刚遇到了同样的问题，我将所有 ActionMessage 更改为 ActionError 并且它有效，听起来就像在 struts 1 中一样，我必须这样做，不确定，但这对我有帮助。

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) 
    {
          .......

          if(!Validation.isValidEmailAddress(getEmailid()))
                  {
              errors.add("emailid", new ActionError("prompt.email.error"));
                  }
          if(!Validation.isPhoneNumberValid(getMobile()))
          {
              errors.add("mobile", new ActionError("prompt.contactno.error"));
          }

          if(!Validation.isNumeric(getPrice()))
          {
              errors.add("price", new ActionError("prompt.price.error"));
          }


        return errors;
    }

i just had the same problem i changed all the ActionMessage to ActionError and it works, sound like in struts 1 i have to do like this not sure but this help me.

public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) 
    {
          .......

          if(!Validation.isValidEmailAddress(getEmailid()))
                  {
              errors.add("emailid", new ActionError("prompt.email.error"));
                  }
          if(!Validation.isPhoneNumberValid(getMobile()))
          {
              errors.add("mobile", new ActionError("prompt.contactno.error"));
          }

          if(!Validation.isNumeric(getPrice()))
          {
              errors.add("price", new ActionError("prompt.price.error"));
          }


        return errors;
    }

在 SubmitPost.jsp 中使用 代替。错误堆栈告诉我。
这是因为 ActionMessage 是 ActionError 的父类。

希望有帮助！

Use <html:messages/> instead in your SubmitPost.jsp. The error stack tells me.
It's due to ActionMessage is the parentClass of ActionError.

Hope it helps!

通过验证，使用 layout:text 而不是 layout:field 标记。

With validation use layout:text instead of layout:field tag.
