利用postMan不會報錯

2.通過map的方式構造json

Map inputMap = new HashMap();
        Map orderMap = new HashMap();
        orderMap.put("buyerName", requestInfoVO.getInfoClientName());
        orderMap.put("buyerTaxNum", requestInfoVO.getInfoClientTaxCode());
        List<Map> invDataList = new ArrayList<Map>();
        for (int i = 0, len = requestInfoVO.getGoodsList().size(); i < len; i++) {
            InvoiceRequestListItemVO itemVO = requestInfoVO.getGoodsList().get(i);
            Map invoiceDetailMap = new HashMap();
            invoiceDetailMap.put("goodsName", itemVO.getGoodsName());
            invoiceDetailMap.put("goodsCode", "");
            invDataList.add(invoiceDetailMap);
        }
        orderMap.put("invoiceDetail", invDataList);
        inputMap.put("order", orderMap);
        String jsonStr = JSON.toJSONString(inputMap);

也可以實現(xiàn)以上的效果親測有效??！

附帶簡潔版：原理一樣

String inputJson = "";
Map inputMap = new HashMap();
// user
Map userMap = new HashMap();
userMap.put("loginName", "));
userMap.put("loginPassword","));
inputMap.put("userInfo", userMap);
// data
Map bussdataMap = new HashMap();
bussdataMap.put("tableName", "");
List<Map> dataList = new ArrayList<Map>();
Map dataMap = new HashMap();
// 
dataMap.put("id", "");
dataMap.put("id_card_no","" );
dataList.add(dataMap);
bussdataMap.put("row", dataList);
inputMap.put("dataInfo", bussdataMap);
// operationType
inputMap.put("operate", "插入");
JSONWriter writer = new JSONWriter(false);
inputJson = writer.write(inputMap);
