在我的jsp页面有一个嵌套列表值的表，我想发送该表值到容器，外表值是发送，但内部表值没有发送到容器中，我是新来的，请让我知道如何在来到这个情况，如何传递嵌套的列表元素到控制器在春天mvc
我的JSP
<script>
function rowAdded(rowElement) {
//clear the imput fields for the row
$(rowElement).find("input").val('');
//may want to reset <select> options etc
//in fact you may want to submit the form
saveNeeded();
}
function rowRemoved(rowElement) {
saveNeeded();
}
function saveNeeded() {
$('#submit').css('color','red');
$('#submit').css('font-weight','bold');
if($('#submit').val().indexOf('!') != 0) {
$('#submit').val('!' + $('#submit').val());
}
}
function beforeSubmit() {
alert('script Working');
return true;
}
$(document).ready(function() {
var config = {
rowClass : 'rule',
addRowId : 'addRule',
removeRowClass : 'removeRule',
formId : 'ruleListForm',
rowContainerId : 'ruleListContainer',
indexedPropertyName : 'ruleList',
indexedPropertyMemberNames : 'id,ruleName,parameterName,overwriteValue',
rowAddedListener : rowAdded,
rowRemovedListener : rowRemoved,
beforeSubmit : beforeSubmit
};
new DynamicListHelper(config);
});
</script>
<html>
<form:form action="/update" method="post" id="ruleListForm" modelAttribute="ruleListContainer">
<table border="1">
<thead>
<h3 align="center">Selected Rule</h3>
<tr>
<th data-field="id" width="25">ID </th>
<th data-field="details" width="20">RuleName </th>
<th data-field="parameter" width="240">Parameter </th>
</tr>
</thead>
<tbody id="ruleListContainer">
<c:forEach items="${List2}" var="as">
<tr class="rule">
<td><input type="hidden" name="ruleList[].id" value="${as.rule.id}" /> ${as.rule.id}</td>
<td><input type="hidden" name="ruleList[].ruleName" value="${as.rule.ruleName}" /> ${as.rule.ruleName}</td>
<td> <input id="one" class="datepicker" type="text" name="ruleList[].startDate" size="11" height="0.10"></td>
<td> <input id="two" class="datepicker" type="text" name="ruleList[].endDate" size="11" height="0.10"></td>
<td>
<table border="1">
<c:forEach items="${as.ruleAssignmentParameter}" var="asss">
<tr>
<td><input type="hidden" name="ruleList[].parameterName"value="${asss.parameterName}" > ${asss.parameterName}</td>
<td><input type="hidden" name="ruleList[].overwriteValue" value="${asss.overwriteValue}" /> ${asss.overwriteValue}</td>
</tr>
</c:forEach>
</table>
</td>
</tr>
</c:forEach>
</tbody>
</table>
<br>
<input type="submit" value="Update">
</form:form>
</html>
，这里是我的模型类
import java.util.Date;
import java.util.LinkedList;
import java.util.List;
import com.demo.app.model.RuleAssignmentParameter;
public class RuleAssUI {
private int id;
private String ruleName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getRuleName() {
return ruleName;
}
public void setRuleName(String ruleName) {
this.ruleName = ruleName;
}
private List<RuleAssignmentParameter> ruleAssignmentParameter = new LinkedList<RuleAssignmentParameter>();
public List<RuleAssignmentParameter> getRuleAssignmentParameter() {
return ruleAssignmentParameter;
}
public void setRuleAssignmentParameter(List<RuleAssignmentParameter> ruleAssignmentParameter) {
this.ruleAssignmentParameter = ruleAssignmentParameter;
}
public RuleAssUI(){
}
public RuleAssUI(int id,String ruleName){
this.id=id;
this.ruleName=ruleName;
}
}
我的容器w ^在这里，我存储列表值
import java.util.LinkedList;
import java.util.List;
public class RuleListContainer {
private List<RuleAssUI> ruleList = new LinkedList<RuleAssUI>();
public RuleListContainer() {
}
public RuleListContainer(List<RuleAssUI> ruleList) {
this.ruleList = ruleList;
}
public List<RuleAssUI> getRuleList() {
return ruleList;
}
public void setRuleList(List<RuleAssUI> ruleList) {
this.ruleList = ruleList;
}
控制器
@RequestMapping(value = "/update", method = RequestMethod.POST)
public String update(@ModelAttribute("SpringWeb") RuleListContainer ruleListContainer, HttpSession session, ModelMap model) {
ruleListContainer.getRuleList().size();
for (RuleAssUI rul1 : ruleListContainer.getRuleList()) {
System.out.println("Id: " + rul1.getId());
System.out.println("RuleName: " + rul1.getRuleName());
for (RuleAssignmentParameter rul2 : rul1.getRuleAssignmentParameter()) {
System.out.println("ParameterName: " + rul2.getParameterName());
System.out.println("ParameterValue: " + rul2.getOverwriteValue());
}
}
session.setAttribute("ruleListContainer", ruleListContainer);
return "hello";
}
我想这么多的时间，但无法修复问题，而且还浏览，但我以前不得到任何适当的帮助，所以请大家帮忙做项目
我需要帮助请一些身体帮助我......！
谢谢你提前

@cralfaro，这个类有一个ruleassignment细节类，我创建List2 – Emad
@cralfaro，我可以填充列表和嵌套列表值表单数据库，这是在List2中，但问题是，当我发送这个值到控制器它不是通过。 – Emad
