服务器用的是Springmvc，接口内容：

	@ResponseBody
	@RequestMapping(value="/order",method=RequestMethod.POST)
	public boolean order(HttpServletRequest request,@RequestBody List<Order> orders) throws Exception {
		AdmPost admPost = SessionUtil.getCurrentAdmPost(request);
		if(admPost == null){
			throw new RuntimeException("[OrderController-saveOrUpdate()] 当前登陆的用户职务信息不能为空！");
		}
		try {
			this.orderService.saveOrderList(orders,admPost);
			Loggers.log("订单管理",admPost.getId(),"导入",new Date(),"导入订单成功,订单信息--> " + GsonUtil.toString(orders, new TypeToken<List<Order>>() {}.getType()));
			return true;
		} catch (Exception e) {
			e.printStackTrace();
			Loggers.log("订单管理",admPost.getId(),"导入",new Date(),"导入订单失败,订单信息--> " + GsonUtil.toString(orders, new TypeToken<List<Order>>() {}.getType()));
			return false;
		}
	}

通过ajax访问的时候，代码如下：

                     $.ajax({
				type : "POST",
				contentType : "application/json; charset=utf-8",
				url : ctx + "order/saveOrUpdate",
				dataType : "json",
				anysc : false,
				data : {orders:[{orderId:"11",createTimeOrder:"2015-08-11"}]},  // Post 方式，data参数不能为空""，如果不传参数，也要写成"{}"，否则contentType将不能附加在Request Headers中。
				success : function(data){
					if (data != undefined && $.parseJSON(data) == true){
						$.messager.show({
							title:'提示信息',
							msg:'保存成功！',
							timeout:5000,
							showType:'slide'
						});
					}else{
						$.messager.alert('提示信息','保存失败!','error');
					}
				},
				error : function(XMLHttpRequest, textStatus, errorThrown) {
					alert(errorThrown + ':' + textStatus); // 错误处理
				}
			});

通过HttpClient方式访问，代码如下：

package com.ec.spring.test;

import java.io.IOException;

		}
	}

	/**
	 * 调用 API
	 * 
	 * @param parameters
	 * @return
	 */
	public String post(String parameters) {
		String body = null;
		logger.info("parameters:" + parameters);

		if (method != null & parameters != null
				&& !"".equals(parameters.trim())) {

				// 建立一个NameValuePair数组，用于存储欲传送的参数
				method.addHeader("Content-type","application/json; charset=utf-8");
				method.setHeader("Accept", "application/json");
				method.setEntity(new StringEntity(parameters, Charset.forName("UTF-8")));
				startTime = System.currentTimeMillis();

				HttpResponse response = httpClient.execute(method);
				
				endTime = System.currentTimeMillis();
				int statusCode = response.getStatusLine().getStatusCode();
				
				logger.info("statusCode:" + statusCode);
				logger.info("调用API 花费时间(单位：毫秒)：" + (endTime - startTime));
				if (statusCode != HttpStatus.SC_OK) {
					logger.error("Method failed:" + response.getStatusLine());
					status = 1;
				}

				// Read the response body
				body = EntityUtils.toString(response.getEntity());

			} catch (IOException e) {
				// 网络错误
				status = 3;
			} finally {
				logger.info("调用接口状态：" + status);
			}

		}
		return body;
	}

	public static void main(String[] args) {
		APIHttpClient ac = new APIHttpClient(apiURL);
		JsonArray arry = new JsonArray();
		JsonObject j = new JsonObject();
		j.addProperty("orderId", "中文");
		j.addProperty("createTimeOrder", "2015-08-11");
		arry.add(j);
		System.out.println(ac.post(arry.toString()));
	}

	/**
	 * 0.成功 1.执行方法失败 2.协议错误 3.网络错误
	 * 
	 * @return the status
	 */
	public int getStatus() {
		return status;
	}

	/**
