如何接收形式不定的Json

[u012525643]

最近公司在让我封装一个UPS公司的“街道级别地址验证”的接口

初步的思路是通过http请求获得json的字符串

然后再使用Jackson将之转化为已写好的实体类，方便之后操作

但是经过测试，发现一个严重的问题，那就是返回的Json格式不定

下面是一个返回的Json的例子：

{
    "XAVResponse": {
        "Response": {
            "ResponseStatus": {
                "Code": "1",
                "Description": "Success"
            }
        },
        "AmbiguousAddressIndicator": "",
        "Candidate": [
            {
                "AddressKeyFormat": {
                    "AddressLine": "100-198 HERNDON PKWY",
                    "PoliticalDivision2": "HERNDON",
                    "PoliticalDivision1": "VA",

                }
            },

                        "STE 130"
                    ],
                    "PoliticalDivision2": "HERNDON",

                }
            }
        ]
    }
}

可以看到 XAVResponse -> Candidate -> AddressKeyFormat下的AddressLine属性一会儿是String，一会儿是List

小弟刚刚工作，技术经验不足，实在是不知道该怎么去接收这样的Json了，难道最后还得用Map操作吗？

求各位前辈指导

js接收这种数据没什么，没有严格类型，服务器端的话就不好搞了 客户端最好处理成一种形式。。要不服务器端序列化为类实例要报错。。可以缺少属性，但是同一个属性不同类型可能处理不了。

就详细街道的区别也很好处理，你判断一下AddressLine是不是数组,如果是就转换成字符保存。或者你自己再加一个详细街道的字段保存数组小标是1的值
