QUESTION

JedisSentinelPool is thread safe?

Asked 2017-Feb-08 at 07:46

I know that jredis is not thread-safe, the Internet should be said that the use of JedisSentinelPool, it is thread-safe, but I use, the discovery is not the case, I do not know whether the use of a problem.

private static Logger logger = LoggerFactory.getLogger(Redis.class);
private JedisSentinelPool pool;

private static Redis instance = null;
public static Redis getInstance(){
    if (instance == null) {
        throw  new RuntimeException("Do not initialize!!!");
    }
    return instance;
}
public static void buildInstance(Map conf) {
    if (instance == null) {
        synchronized (Redis.class) {
            instance = new Redis();
            instance.init(conf);
        }
    }
}

private Redis() {}

private void init(Map conf){
    JedisPoolConfig config = new JedisPoolConfig();
    config.setMaxIdle(Integer.valueOf(String.valueOf(conf.get("redis.max_idle"))));
    config.setTestOnBorrow(Boolean.valueOf(String.valueOf(conf.get("redis.isTest"))));
    config.setMaxTotal(Integer.valueOf(String.valueOf(conf.get("redis.maxTotal"))));
    String node = String.valueOf(conf.get("redis.node"));
    int timeOut = Integer.valueOf(String.valueOf(conf.get("redis.timeout")));
    String[] addressArr = String.valueOf(conf.get("redis.server")).split(",");
    Set<String> sentinels = new HashSet<String>();
    for (String str : addressArr) {
        sentinels.add(str);
    }
    pool = new JedisSentinelPool(node, sentinels, config, timeOut);
}

private Jedis getRedisTemplate() {
    Jedis resource = pool.getResource();
    return resource;
}

/** public */void setValue(byte[] key, byte[] value) {
    Jedis jedis = null;
    try {
        jedis = getRedisTemplate();
        jedis.set(key, value);
        closeJedis(jedis);
    } catch (Exception e) {
        e.printStackTrace();
        closeBreakJedis(jedis);
