Question

我正在使用 Johm 来缓存和检索 Redis 数据库中的一些数据。但是，当我想要提取的对象数据像使用 JOhm.getAll(MT.class);例如我得到一个异常

   redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketTimeoutException: Read timed out
        at redis.clients.jedis.Protocol.process(Protocol.java:85)
        at redis.clients.jedis.Protocol.read(Protocol.java:137)

这是我的 Johm 设置

public class Redis {

    @SuppressWarnings("unused")
    private static Logger logger = LoggerFactory.getLogger(Redis.class);
    private static Redis redis = new Redis();
    protected JedisPool jedisPool;

    /**
     * 
     */
    private Redis() {
        jedisPool = new JedisPool(new Config(), "localhost", 6379);
        JOhm.setPool(jedisPool);
        // purgeRedis();
    }

    protected void purgeRedis() {
        Jedis jedis = jedisPool.getResource();
        jedis.flushAll();
        jedisPool.returnResource(jedis);
    }

    public synchronized static Redis getInstance() {
        if (redis == null)
            redis = new Redis();
        return redis;
    }

    @Override
    protected Object clone() throws CloneNotSupportedException {
        throw new CloneNotSupportedException("Clone is not allowed.");
    }

}

还有这个检索功能：

public Set<MT> getAll(){
    return JOhm.getAll(MT.class);
}

我的 Redis 已启动并正在运行 有人可以帮助我吗？

这是一个连接问题。

检查您正在尝试连接到正确的地址，并且您的所有连接配置都正确。
