listjson_103">二 、将list转为json对象存取

1. import com.alibaba.fastjson.JSON;

2. import com.alibaba.fastjson.JSONObject;

3. @Autowired

4. private StringRedisTemplate stringRedisTemplate;

5. //存

6. List businessIdList = eeFreecarriageShopService.selectBusinessIdInPromotion();

7. stringRedisTemplate.opsForValue().set(RedisConstants.FREECARRIAGE_BUSINESSIDLIST, JSON.toJSON(businessIdList).toString());

8. //取

9. String businessJsonArray = stringRedisTemplate.opsForValue().get(RedisConstants.FREECARRIAGE_BUSINESSIDLIST);

10. List businessIdList = JSONObject.parseArray(businessJsonArray,Long.class);
