Use Gson to parse complex, perverted JSON data

Interface Documentation:

App Configuration Interface client/init request data JSON={"UID": "", "Sid": "", "ver": "1",    "Request": {}} returned data {"ret": 0,    "Response":{        "Tag_category":{            Chinese painting:{                "Age": ["pre-Qin and Han dynasties", "The Warring states Chu", "Wei Jin North and South", "Sui and Tang Dynasties", "Southern Song Dynasty", "Yuan Dynasty", "Ming and Qing", "modern", "Age Unknown", "other"],                "Technique": ["Splash", "meticulous", "freehand", "Baimiao", "sketch", "Texturing method", "No Bone", "finger painting", "other"],                ...            },            Calligraphy:{                "Classification": ["calligraphy", "rubbing from", "Writing scripture", "Letters clerical", "other"],                "Chirography": ["Seal Script", "script", "Regular script", "cursive", "Running script", "other"],                ...            },            ...        } }} Note tag_category label classification

First of all naturally think of encapsulation into JavaBean.

Note the point:

1, the internal nested class must be static, otherwise the parsing will be wrong;

2. The attribute name inside the class must be identical to the key in the JSON field;

3. Because the key in the JSON field exists in Chinese, you must use the @serializedname ("Chinese painting") annotation on the corresponding field to alias the key.

4, internal embedded {} is defined as public chinapicture chinapicture, the part enclosed in [] is a List, so it is defined as public list<string> years.

5. If you do not want to write the get and set methods, you only need to define the fields as public.
