如何访问JSON的嵌套元素并将其转换为CSV

以下是我需要访问的JSON

{
    "Timestamp": "2014-05-28 03:31:59",
    "Version": 1,
    "ACK": "success",
    "Errors": {
        "ErrorCode": "433",
        "ShortMessage": "success",
        "LongMessage": "Successfully get all cate information",

    },

问题是什么？你在用什么编程？首先，我需要从Java中的JSON中检索元素。试过使用JsonGen，但不起作用。你能分享一些代码吗；JsonObject JsonObject=parser.parseline.getAsJsonObject；Set productsJson=jsonObject.getdata.getAsJsonObject.entrySet；List allProductData=new ArrayList；ProductData1产品=新产品Data1；forEntry oneProductJson:productsJson{product.setCategory\u idoneProductJson.getKey；System.out.printlnoneProductJson.getKey+'\n'；我只能检索密钥，但无法进入。非常感谢您的帮助
