java 如何提交list 到后台

1、在jsp 隐藏提交多个name相同的值

<c:forEach items="${deliveryNoticeList}" var="item" varStatus="status">
										<tr>
											<td>
												<span>${status.index +1 }</span>
											</td>
											<td><input type="checkbox" class="ajxa" name="id" />
											<input type="hidden" name="contractCode" value="${item.contractCode }"/>
											<input type="hidden" name="outstoreNo" value="${item.outstoreNo }"/>
											<input type="hidden" name="deliveryCode" value="${item.deliveryCode }"/>
											<input type="hidden" name="status" value="${item.status }"/>
											<textarea></textarea>
											</td>

2、js 脚本处理 

var ids = $("#tab").find("[name='id']");
	var statuss = $("#tab").find("[name='status']");
	var contractCodes = $("#tab").find("[name='contractCode']");
	var outstoreNos = $("#tab").find("[name='outstoreNo']");
	var deliveryCodes = $("#tab").find("[name='deliveryCode']");
	
	
	if(flag){

		var objArray = [];
		$(ids).each(function(i) {
			if ($(this).prop('checked')) {
				var obj = {};
				obj["contractCode"] = $(contractCodes[i]).val();
				obj["deliveryCode"] = $(deliveryCodes[i]).val();
				obj["outstoreNo"] 	= $(outstoreNos[i]).val();
				objArray.push(obj);

			}
		});
		var objlist = {"list":JSON.stringify(objArray)};
		$.ajax({
			cache: true,
			type: "POST",
			url: CTX + "/customer/batchAffirm",
			data:objlist,   
			async: false,
			error: function(request) {},
			success : function(data) {}
		});
		window.location = CTX + "/customer/confirm";
	}

3、java的Controller接收处理

import com.fasterxml.jackson.databind.ObjectMapper;
String list = request.getParameter("list");
List<Box> boxList =null;
ObjectMapper objectMapper  = new ObjectMapper();
if(StringUtils.isNotBlank(list)){
	boxList = objectMapper.readValue(list, objectMapper.getTypeFactory().constructCollectionType(List.class,Box.class));
}
