我的問題是，當我沒有看到客戶端驗證錯誤消息時，即使在配置時沒有爲該字段輸入任何值按要求。頁面重新加載並轉到結果頁面，客戶端驗證失敗。我不確定我做錯了什麼。使用Struts 2進行客戶端驗證的問題。基於Xml的驗證規則不被識別
我有一個簡單的形式，我有一個名爲選擇標準的下拉菜單。必須選擇一個值。如果未選擇某個值，則應使用已配置的錯誤消息重新加載頁面。我在下面輸入表格action_item_search.jsp給出：
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Action Item Search</title>
</head>
<body>
<s:actionerror/>
<s:fielderror />
<s:form action="action_item_search" validate="true">
<s:select label="Search Criterion" name="searchCriterion"
list="#{'': 'Select One', 'creatorName':'creator name',
assignedTo':'assigned to'}" required="true" />
<s:submit name="search" value="Search"></s:submit>
</s:form>
</body>
我有爆炸的戰爭文件的我的WEB-INF/classes目錄下添加validators.xml，如下所示：
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator Config 1.0//EN"
"http://www.opensymphony.com/xwork/xwork-validator-config-1.0.dtd">

ActionItemTrackingAction，findByCriteria-
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
<field name="searchCriterion" >
<field-validator type="required">
<message>You must enter a search criterion.</message>
</field-validator>
</field>
</validators>
我的支柱映射XML：
在WEB-INF/classes目錄的validation.xml下面給出<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<!-- <include file="example.xml"/> -->
<package name="action-item" extends="struts-default">
<action name = "action_item_search_input">
<result name = "success">/action-item-search.jsp</result>
</action>
<action name="action_item_search" class="gov.nasa.spacebook.ActionItemTrackingAction" method="fetchByCriteria">
<result name = "success">/action-item-result.jsp</result>
<result name = "input">/action-item-search.jsp</result>
<result name = "error">/action-item-search.jsp</result>
</action>
</package>
</struts>
我的動作類
public class ActionItemTrackingAction extends ActionSupport {
private List<ActionItem> actionItems;
public List<ActionItemTracking> getActionItems() {
return actionItems;
}
public void setActionItems(List<ActionItemTracking> actionItems) {
this.actionItems = actionItems;
}
private String searchCriterion;
public String getSearchCriterion() {
return searchCriterion;
}
public void setSearchCriterion(final String criterion) {
this.searchCriterion = criterion;
}
public String fetchByCriteria() throws Exception {
final ActionItemTrackingService service =
new ActionItemTrackingService();
this.actionItems = service.getByField(this.actionItem);
return super.execute();
}
}
我有類似的問題。我正在使用Validateable接口，並且在我提交表單時工作正常。但是我發現在s：form的標籤中沒有設置validate ='true'的區別。在我看來，如果客戶端驗證JavaScript代碼沒有成功生成。 – Akku 2011-06-15 12:49:45
我不確定什麼可能是實際問題，但請參閱此鏈接http://struts.apache.org/2.0.6/docs/client-side-validation.html，它可能有幫助 – Binay 2012-10-15 11:00:28
