删除写入redis数据

@Override
    public void deleteRedis(String deviceId) {
        stringRedisTemplate.delete(deviceId);
    }

    @Override
    public void saveRedis(CoreDevice coreDevice) {

           String deviceId = coreDevice.getDeviceId();
        //数据库里存在，则将信息写入Redis
        try {
            String deviceJSon = objectMapper.writeValueAsString(coreDevice);
            stringRedisTemplate.opsForValue().set(deviceId, deviceJSon);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
}
