JSON与List的相互转化_hutool list转json

1.依赖导入

        <!--hutool-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.7.17</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.66</version>
        </dependency>

2.List转化为JSON

ArrayList<String> list= new ArrayList();
String Json = JSONUtil.toJsonStr(list);
stringRedisTemplate.opsForValue().set("list",Json );

3.JSON转换成List集合

String s= stringRedisTemplate.opsForValue().get("key");
List<类名> list = JSONObject.parseArray(s, 类名.class);

注：JSONObject采用fastjson工具包
