json转bean对象

Posted 2020-06-25 小安妮的熊

一下为个人收藏，以便下次使用。

前端传的json格式为：

[{"suppliercode":"gylhld_gycqlt3_gycqlt1","productname":"乐和乐都套票(成人)","datahandelmethod":"1","producttype":"1","yscpcbj":"140","effectivetime":"2016-01-27 00:00:00","invalidtime":"2016-02-29 00:00:00","status":"1","id":"7066cb7c-fd52-4949-b7a1-776812995023","organid":"","summaryurl":"","createtime":"2016-01-29 16:25:46","createuserid":"0b8d60c9-c3b6-498f-a7f2-a28b7bf99232","createuser":"兰洋","updateuserid":"0b8d60c9-c3b6-498f-a7f2-a28b7bf99232","updatetime":"2016-01-29 16:25:46","updateuser":"兰洋"}]

　　我们最终的目的是将json传转为对象

如下获取一个params参数：

HttpServletRequest request = getContext().getRequest();
        String params = request.getParameter("params");
        JSONArray array = JSONArray.fromObject(params);//先读取串数组
        Object[] o = array.toArray();//转成对像数组
        JSONObject obj = JSONObject.fromObject(o[0]);//再使用JsonObject遍历一个个的对像
        Shopgoodsprductys shopgoodsprductys = (Shopgoodsprductys)obj.toBean(obj,Shopgoodsprductys.class);//指定转换的类型，但仍需要强制转化-成功

前端传参数格式例如：

var shopgoodsprductys = [];
        shopgoodsprductys.push({
            "suppliercode":suppliercode,
            "productname":productname,
            "datahandelmethod":datahandelmethod,
            "producttype":producttype,
            "yscpcbj":yscpcbj,
            "effectivetime":effectivetime,
            "invalidtime":invalidtime,
            "status":status,
            "id":id
            ........
            
        });

var params = JSON.stringify(shopgoodsprductys);
        $.ajax({ 
            type: ‘POST‘, 
            data: {params:params}, 
            url: getbasePathUrl(‘zxxt/Shopgoodsprductys.action?saveShopgoodsprductys=‘),
            dataType:"json",
            success: function (result) {
                alert("操作成功");
            },
            error: function (xhr) {
                alert("操作失败");
            } 
        });
