rich：日历本机验证隐藏/覆盖/ ??我的bean验证错误

我的应用程序使用rich：calendars和h：inputText。如果我在intputText（即非数字数据）的UI中输入不良数据，并按下“Search”，我会从bean中获取正确的错误消息。但是，如果我在inputText（非数字）和rich：日历（非日期相关的输入，例如“foo”）中输入了无效数据，我只会返回rich：calendar错误消息。就好像本地丰富的日历验证消息敲出了bean验证消息。rich：日历本机验证隐藏/覆盖/ ??我的bean验证错误

如何获取所有要显示的消息？

的XHTML代码如下：

<html xmlns:f="http://java.sun.com/jsf/core" 
     xmlns:ui="http://java.sun.com/jsf/facelets" xmlns="http://www.w3.org/1999/xhtml" 
     xmlns:a4j="http://richfaces.org/a4j" 
     xmlns:h="http://java.sun.com/jsf/html" 
     xmlns:tr="http://myfaces.apache.org/trinidad" 
     xmlns:rich="http://richfaces.org/rich"> 
<f:view> 
    <br/> 
    <div class="container"> 
    <tr:form id="searchCriteria" defaultCommand="appealSearchManager.search"> 
     <a4j:outputPanel id="errorMessagesPanel"> 
      <h:messages id="errorMessages"/> 
     </a4j:outputPanel> 
     <div class="div30"> 
      <p><h:outputText value="#{messages.ProgramInvoiceId}"/></p> 
      <h:inputText id="programInvoiceId" value="#{appealSearchManager.programInvoiceId}"/> 
     </div> 
     <div class="div30"> 
     <p><h:outputText value="#{messages.ResponseReleaseDate}"/></p> 
     <rich:calendar id="responseReleaseDateBegin" 
      enableManualInput="true" datePattern="MM/dd/yyyy" 
      buttonIcon="/images/calendar_icon.jpg" buttonClass="calendar" 
      converterMessage="Invalid Response Release begin date. Format must be blah, blah, blah." 
      value="#{appealSearchManager.responseReleaseDateBegin}"> 
     </rich:calendar> 
     <rich:calendar id="responseReleaseDateEnd" 
      enableManualInput="true" datePattern="MM/dd/yyyy" 
      buttonIcon="/images/calendar_icon.jpg" buttonClass="calendar" 
      converterMessage="Invalid Response Release End date. Format must be blah, blah, blah." 
      value="#{appealSearchManager.responseReleaseDateEnd}"> 
     </rich:calendar> 
     </div> 

     <div class="searchaction"> 
      <div> 
       <ul> 

        <li> 
         <a4j:commandLink id="searchButton" 
             value="#{messages.Search}" 
             actionListener="#{appealSearchManager.search}" 
             reRender="errorMessagesPanel, richErrorMessages, errorMessages" 
             styleClass="searchbtn"/> 
        </li> 
       </ul> 
      </div> 
     </div> 
    </tr:form> 
    </div> 
</f:view> 
</html>

和bean代码：

public void search(ActionEvent e) { 
    setHasErrors(validateCriteria()); 
} 

private boolean validateCriteria() { 
    boolean isValid = true; 
    //always check for Program Invoice ID may contain a comma-separated list of ids 
    if (getProgramInvoiceId() != null && !getProgramInvoiceId().equals("") && !areValidProgamInvoiceIds(getProgramInvoiceId())) { 
     String errorMessage = "Invalid Program Invoice ID. Must be comma delimited list of numbers."; 
     FacesContext.getCurrentInstance().addMessage(null, 
                new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMessage, errorMessage)); 
     isValid = false; 
    } 
    //check Dates Response Release Date 
    if (!isValidDateRange("Response Release Date", getResponseReleaseDateBegin(), getResponseReleaseDateEnd())) { 
     isValid = false; 
    } 
    return isValid; 
} 

private boolean areValidProgamInvoiceIds(String ids) { 
    boolean validIds = true; 
    String regexp = "^([0-9]+(-[0-9]+)*,*)+$"; 
    Pattern pattern = Pattern.compile(regexp); 
    if (!pattern.matcher(ids).matches()) { 
     validIds = false; 
    } 
    return validIds; 
} 

private boolean isValidDateRange(String dateRange, Date startDate, Date endDate) { 
    boolean isValidDateAndRange = true; 
    Calendar futureDate = Calendar.getInstance(); 
    futureDate.roll(Calendar.DAY_OF_MONTH, 2); 
    if ((startDate != null && (endDate == null || endDate.equals(""))) || 
     ((startDate == null || startDate.equals("")) && endDate != null)) { 
     //one date is null and the other has a value. We need both values to do a search. 
     String errorMessage = "Invalid " + dateRange + " range. Missing Date. A date range must contain both start and end dates."; 
     FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMessage, errorMessage)); 
    } else if (startDate != null && endDate != null) { 
     if (isValidDateAndRange) { 
      //future start dates are not allowed 
      if (startDate.after(futureDate.getTime())) { 
       String errorMessage = "Invalid date range. Start date must be less than today's date."; 
       FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMessage, errorMessage)); 
       isValidDateAndRange = false; 
      } 
      //start date greater than the end date is not allowed 
      if (endDate.before(startDate)) { 
       String errorMessage = "Invalid date range. End date must be greater than or equal to start date."; 
       FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, errorMessage, errorMessage)); 
       isValidDateAndRange = false; 
      } 
     } 
    } 
    return isValidDateAndRange; 
}

任何建议，将不胜感激。谢谢！

您不应该在动作方法中执行验证。您应该使用正常的Validator执行此操作，该操作通过<f:validator>或任何标准<f:validateXxx>标签绑定。验证失败时从不调用操作方法。

例如，要验证程序发票ID，请使用<f:validateRegex>。

<h:inputText id="programInvoiceId" value="#{appealSearchManager.programInvoiceId}" validatorMessage="Invalid Program Invoice ID. Must be comma delimited list of numbers."> 
    <f:validateRegex pattern="^([0-9]+(-[0-9]+)*,*)+$" /> 
</h:inputText>

验证日期范围有点复杂。至此，您需要将Validator类作为<f:validator>放在其中一个组件上，并将另一个组件的值作为属性传递。有关示例，另请参阅Compare two fields that use same class。

顺便说一句，注意术语，你是而不是根本就是使用"bean validation"，但你只是在动作方法中手动验证。

我喜欢使用的但要求状态，我要收集所有的错误，并显示他们一个jQuery的弹出式:-( – 2012-03-14 14:50:26

顺便说一句 - 感谢澄清术语....是一个新手我仍然在理解正确的单词，我会尝试验证日期范围，如上所述。谢谢！ – 2012-03-14 14:53:10

酷日期验证！像魅力一样工作。谢谢你!! – 2012-03-14 14:55:39
