GSON似乎是JSON的升级版

引入GSON包后，编写代码。

GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.setPrettyPrinting();
gsonBuilder.setFieldNamingStrategy(new FieldNamingStrategy() {

    @Override
    public String translateName(Field f) {
        if(f.getName().equals("name")){
            return "NAME";
        }
        return f.getName();
    }
});

Gson gson = gsonBuilder.create();
System.out.println(gson.toJson(kaijinge));
