I use jedis to access Redis but sometimes it throws JedisConnection,message is Unexpected end of stream ,can anyone help me ?

the followering is my code:

public static JedisPool jedisPool = null;

public static void init(){

jedisPool =new JedisPool(new GenericObjectPoolConfig(), REDIS_HOST, REDIS_PORT, Protocol.DEFAULT_TIMEOUT, REDIS_PASS,

Protocol.DEFAULT_DATABASE, null);

}

public static void set(String key,String value){

try(Jedis jedis = jedisPool.getResource()){

jedis.set(key, value);

logger.debug("redis set {}:{}", key, value);

}

when invoke the static set method,but it is very strange that it does not occures every time.I google for days someone said that it may be concurrent problem but jedisPool is thread safe according to the document,so I am totaly confused.

Yes.

Try setting the "timeout" option to 0 and see if the problem gets fixed.
