Spring中Redis存取数据示例

1.导入StringRedisTemplate类

import org.springframework.data.redis.core.StringRedisTemplate;

2.自动装配

@Autowired
private StringRedisTemplate stringRedisTemplate;

3.存数据（设置5分钟过期）

String token = UUID.randomUUID().toString();
String key = RedisPrefixConstants.WORK_ORDER_EXCEL_TOKEN_PREFIX + token;
stringRedisTemplate.opsForValue().set(key, workId, 60 * 5, TimeUnit.SECONDS);

4.取数据

String key = RedisPrefixConstants.WORK_ORDER_EXCEL_TOKEN_PREFIX + token;
String wordIdCache = stringRedisTemplate.opsForValue().get(key);
if (wordIdCache == null || !wordIdCache.equals(workId)) {
    throw new com.cmit.kapok.base.core.ServiceException("token已失效");
}

//todo 暂时放开限制，测试安卓无法下载问题
stringRedisTemplate.expire(key,1,TimeUnit.MINUTES);
//stringRedisTemplate.delete(key);
