我正在编写用于添加和查看供应商的代码。但问题是，我添加了一个dataexporter来以不同的格式导出表。当我单击dataexporter时，它会验证inpuut字段而不是导出数据表。见下面的代码，
<h:panelGrid columns="6">
<p:outputLabel value="Vendor Name: " for="vname"/>
<p:inputText id="vname" required="true" value="#{bank.vendor_name}" />
<p:message for="vname"/>
<p:outputLabel value="Vendor Bank: " for="bank"/>
<p:selectOneMenu id="bank" value="#{bank.bankmode.bankName}" required="true" requiredMessage="Bank required">
<f:selectItem itemLabel="--Select Bank--" itemValue="" noSelectionOption="true"/>
<f:selectItems value="#{bank.bankmodel}"
var="singlevalue"
itemLabel="#{singlevalue.bankName}"
itemValue="#{singlevalue.bankName}"/>
</p:selectOneMenu>
<p:message for="bank"/>
<p:outputLabel value="Vendor Account Number: " for="anum"/>
<p:inputText id="anum" required="true" value="#{bank.vendor_acct}" requiredMessage="Account Number required" />
<p:message for="anum"/>
<p:outputLabel value="Vendor Contact Address: " for="adress"/>
<p:inputTextarea id="adress" required="true" value="#{bank.vendor_address}" requiredMessage="Contact Address required" />
<p:message for="adress"/>
<p:outputLabel value="Vendor Email Address: " for="email"/>
<p:inputText id="email" required="true" label="email" size="40"
requiredMessage="Please enter your email address."
validatorMessage="Invalid email format"
value="#{bank.vendor_email}">

请协助。我一直试图解决这个问题，并继续得到同样的结果。感谢

JSF有6个生命周期阶段。其中之一是Process Validation阶段。在该阶段，进行输入组件（例如，输入字段）的验证。在您的情况下，您不希望进行验证。所以你要做的是在命令链接组件中添加immediate属性：
<h:commandLink immediate="true">
<p:graphicImage value="/images/excel.png" />
<p:dataExporter type="xls" target="singleTB" fileName="report" pageOnly="true"/>
</h:commandLink>
通过此设置，将跳过Apply Request Values到Render Response阶段之后的所有生命周期阶段。
