Question

我正在做一个从json到csv文件的转换器。我已尝试过此链接的解决方案，但无法正常运行：Converting JSON to XLS/CSV in Java

问题是我没有单独列中的数据，而且我的列名也不同。有可能解决这个问题吗？

我的json看起来像这样：

{
 "Code":2,
 "Description":"OK",
 "Status":0,
 "Items":[{ "City":"nameOfCity",
        "Country":"nameOfCountry",
        "CountryCode":"US",
        "Latitude":"11.11111",
        "Longitude":"-11.11111",
        "Name":"name of Company",
        "Region":"nameofRegion",
        "ServisID":"111AAA111AA",
        "SiteAddress":"number and street 2301",
        "ZipCode":"1111"},
        {"City":"nameOfCity2",
        "Country":"nameOfCountry",
        "CountryCode":"US",
        "Latitude":"22.22222",
        "Longitude":"22.2222222222",
        "Name":"name of Company2",
        "Region":"nameofRegion",
        "ServisID":"111BBB111BB",
        "SiteAddress":null,
        "ZipCode":null}
        , ...etc.

我的代码：

String bodyStr = new String(proxyResponse.getBody());

JSONObject output;

try {
    output = new JSONObject(bodyStr);

    JSONArray docs = output.getJSONArray("Items");

    File file = new File("C:/folder/fromJSON.csv");
    String csv = CDL.toString(docs);
    FileUtils.writeStringToFile(file, csv);


    } catch (JSONException e) {
                e.printStackTrace();
    } catch (IOException e) {
                e.printStackTrace();
    }
}

结果（首次预期）：

使用以下代码按预期工作。我发现你和我的代码之间没有任何重大差异......

public static void main(String[] args) throws IOException {
        String inputJson = "{\"Code\":2,\"Description\":\"OK\",\"Status\":0,\"Items\":[{\"City\":\"nameOfCity\",\"Country\":\"nameOfCountry\",\"CountryCode\":\"US\",\"Latitude\":\"11.11111\",\"Longitude\":\"-11.11111\",\"Name\":\"name of Company\",\"Region\":\"nameofRegion\",\"ServisID\":\"111AAA111AA\",\"SiteAddress\":\"number and street 2301\",\"ZipCode\":\"1111\"},{\"City\":\"nameOfCity2\",\"Country\":\"nameOfCountry\",\"CountryCode\":\"US\",\"Latitude\":\"22.22222\",\"Longitude\":\"22.2222222222\",\"Name\":\"name of Company2\",\"Region\":\"nameofRegion\",\"ServisID\":\"111BBB111BB\",\"SiteAddress\":"
                + null + ",\"ZipCode\":" + null + "}]}";
        JSONObject objJsonObject = new JSONObject(inputJson);
        JSONArray objJsonArray = objJsonObject.getJSONArray("Items");
        String csv = CDL.toString(objJsonArray);
        FileUtils.writeStringToFile(new File(System.getenv("HOME")+ "/temp.csv"), csv);
}

我使用带有UTF-8编码的libreoffice v5.1打开了csv文件
