JSON, String，Map，实体对象之间的转换

String转Map

Map<String, Object> maps = (Map<String, Object>) JSON.parse(jsonObject);

Map maps = (Map) JSON.parse(jsonObject);

String转实体对象

 BankCardData bankCardData = JSONObject.parseObject(result, BankCardData.class);

Map转实体String

 String result = maps.get("result").toString();

Map转实体 

Student entity = JSON.parseObject(JSON.toJSONString(map), Student.class);

String转List

List<Student> list = JSONArray.parseArray(arrayStr,Student.class);

实体对象转String

String s = JSONObject.toJSONString(ordersVo);

JSON转实体对象

 FoodPermit foodPermit1 = JSON.parseObject(JSONObject_result.toString(), FoodPermit.class);

 需要引入依赖

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>fastjson</artifactId>
    <version>1.2.54</version>
</dependency>

​掌握这些就可以互转了哈!​
