Java 多条数据提交，前台js如何传值，后台如何接参

     先上图，就类似一次性添加 多个商品

 HTML

	
	 
		

			
医嘱编码
			
药品名称
			
生产批号
			
数量
			
剂量
			
频率
			
用药途径
			
备注
		
		

			

			

			

			

			

			

			

			

			

		
	
		

			
			 
		

 JS

function btnyizhu() {
			var hos_id = $("[name='hos_id']").val();
			var bed_id = $("[name='bed_id']").val();
			var patient_name = $("[name='patient_name']").val();
			var sex = $("[name='sex']").val();
			var age = $("[name='age']").val();
			var instro_doctor = $("[name='instro_doctor']").val();
			var instro_date = $("[name='instro_date']").val();
 
				var data = {
					hos_id : hos_id,
					bed_id : bed_id,
					patient_name : patient_name,
					sex : sex,
					age : age,
					instro_doctor : instro_doctor,
					instro_date : instro_date,
					instro_id : instro_id,
					drugs_name : drugs_name,
					pro_num : pro_num,
					quantity : quantity,
					dose : dose,
					freequency : freequency,
					method : method,
					remark : remark
				};
				$.ajax({
					url : "addYiZhu",
					dataType : "json",
					contentType : "application/json;charsetset=UTF-8",//必
					type : "post",
					cache : false,
					data: JSON.stringify(data),//必须
					success : function(obj) {
						if (obj == "400") {
							layer.alert('医嘱生成成功！', function(index) {
								window.location.reload();
							});
						} else if (obj == "404") {

							layer.alert("该药品库存不足！！！");
						} else {
							layer.alert("医嘱生成失败，请查看网络！！！");
						}
					},
					error : function(textStatus, e) {
						layer.alert("系统ajax交互错误: ");
					}
				});
			}

		}

 后台接受多个参数

Controller控制层
//提交医嘱
	@RequestMapping(value="addYiZhu",method=RequestMethod.POST, produces = {"application/json; charset=UTF-8"})
	@ResponseBody
	public String  addYiZhuOrder(@RequestBody JSONObject obj){
		return  drugService.addYiZhuOrder(obj);
	}

serviceImpl 业务层
@Override
	@Transactional
	public String addYiZhuOrder(JSONObject obj) {

OVER 是不是很简单啊，里面有些代码被我剪掉了，不影响大局。
