<>复杂json数据的解析

<求助>复杂json数据的解析
请求接口，返回这样的多层嵌套的json数据。一两层还能解析。复杂的就傻眼了。另外使用gsonFormat生不成实体类，自己拆分，写的实体类，解析不出来。好坑。求助各位，不吝赐教。
json  数据如下。     {
    "data": {
        "id": 39,
        "name": "商标注册--测试",
        "productAttributes": [
            {
                "addressAttribute": [

                            },
                            {

                        "priceAdjustment": 600.0000,

                    }
                ],

gsonformat怎么生不成实体类？

http://blog.****.net/crazy1235/article/details/48598803#gosnformat
------解决思路----------------------
你一层一层解析呗，从外面开始。先去拿这个json测试了，然后再简单封装一下
------解决思路----------------------
http://www.jsonschema2pojo.org/   在线Json转POJO，Source type选择JSON，Annotation style选Gson，之后点击Preview按钮即可自动转换成POJO。
------解决思路----------------------
网上下载一个谷歌Gson的jar包，然后用Gson解析比较快，也是一层一层的剥，需要哪层就剥到哪层
