HttpClient通过Post方式发送Json数据

服务器用的是Springmvc，接口内容：

[java] view plain copy

print?

@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：

[javascript] view plain copy

print?

$.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：

[java] view plain copy

print?

}

/**

public String post(String parameters) {

String body = null;

logger.info("调用API 花费时间(单位：毫秒)：" + (endTime - startTime));

if (statusCode != HttpStatus.SC_OK) {

}

// Read the response body

} catch (IOException e) {
