序列化、持久化：将Goods对象转化为JSON对象

Goods goods=new Goods("香蕉","夏威夷香蕉",100,400);
        String json=JSON.toJSONString(goods);
        System.out.println(json);

反序列化：将JSON对象转化为Goods对象

String s="{\"des\":\"夏威夷香蕉\",\"inventory\":400,\"name\":\"香蕉\",\"price\":100}";
        Goods goods=JSON.parseObject(s,Goods.class);
        System.out.println(goods.getName()+" "+goods.getDes()+" "+goods.getInventory()
        +" "+goods.getPrice());

304-使用fastjson解析json和序列化对象

序列化:

String json=JSON.toJSONString(goods);

反序列化:

String s="";

Goods goods=JSON.parseObject(s, Goods.class);
