后台解析前台传入的对象为空

前台传入object对象，后台解析数据

var myDatas = new Object();
         myDatas={
          commodity_name : '1',//产品名称 $('#chanpinmingcheng')
          commodity_marketprice : '1',//市场价 $('#shichangjia')
          commodity_stock : '1',//产品数量 $('#chanpinshuliang')
          commodity_bit : '1',//少量标准1 之数量区间 $('#-'); //select box
          commodity_bit_price : '1',//少量标准1 之数量区间价格 $('#cahnpinjiage-01');
          commodity_abundance : '1',//大量标准1 之数量区间 $('#-'); //select box
          modity_abundance_price : '1',//大量标准1 之数量区间 $('#myjiage1'); //select box
          commodity_deliverytime : '1', //发货期 $('#fahuoqi');
          commodity_deliveraddress : '1',//发货地 $('#regAddress')
          commodity_unit : '1',//产品单位 select box
          commodity_class : CookieUtil.get('tag1')+'/'+CookieUtil.get('tag2')+'/'+CookieUtil.get('tag3')
         }

 $.ajax({
                  url : getUrl()+'ReleaseProduct',
                  dataType : 'json',
                  type : 'get',
                  data : {
                    token : CookieUtil.get('token'),
                    userId : CookieUtil.get('userId'),
                    category : myDatas
                  },
                  success : function(){
                    console.log('发送成功');
                  }
                })

前台解析数据输出

{"commodity_name":"1","commodity_marketprice":"1","commodity_stock":"1","commodity_bit":"","commodity_bit_price":"1","commodity_abundance":"","modity_abundance_price":"1","commodity_deliverytime":"1","commodity_deliveraddress":"天津","commodity_unit":"","commodity_class":"安全、防护/锁具/自行车锁"}

后台接收到数据解析

public Object ReleaseProduct(String token,long userId,Object category) {
		// TODO Auto-generated method stub
		if(!IsToken.isToken(token,userId)){
			json.put("msg", "身份过期");
			return json;
		}
		System.out.println(Json.toJson(category));
		List<Shop_commodity> list=Json.fromJsonAsList(Shop_commodity.class, Json.toJson(category));
		shop_commodityDao.addShop_commodityForList(list);
		json.put("msg", "产品信息发布成功");
		return json;
	}

这是入口方法吗？注解贴全

这是入口方法

	@At("/ReleaseProduct")
	@Ok("json:{locked:'password|salt'}")
	public Object ReleaseProduct(@Param("token")String token,@Param("userId")long userId,
			@Param("..")Object category){
		System.out.println("000000000");
		IShopService iShopService = new ShopService();
		System.out.println("==:"+category);
		return iShopService.ReleaseProduct(token, userId, category);
	}

改成

@Param("category")String category

qq_68fbea12 4楼•2809天前

把这个所对的入口方法和service的类型都改成Stirng
数据输出成null

==:null
null

注意看@Param的值

qq_68fbea12 6楼•2809天前

@At("/ReleaseProduct")
	@Ok("json:{locked:'password|salt'}")
	public Object ReleaseProduct(@Param("token")String token,@Param("userId")long userId,
			@Param("category")String category){
		System.out.println("000000000");
		IShopService iShopService = new ShopService();
		System.out.println("==:"+category);
		return iShopService.ReleaseProduct(token, userId, category);
	}

@qq_68fbea12 鉴于前端已经把category转为字符串，那么取出的方式跟token无异的，仔细检查一下吧

category要在页面转json字符串，这样就跟token/userId就没差别了

这个问题解决了，是因为category传到后台的时候转码错误，所以后台接收到的数据null
