I have web application Spring+Spring MVC in Eclipse (OS WIN 10).

I have the following mavenized setup:

<spring.version>5.1.2.RELEASE</spring.version>

<spring-data-redis.version>2.1.2.RELEASE</spring-data-redis.version>

<jedis.version>2.9.0</jedis.version>

I've created function:

@Override

public Map<String, Double> find(final String set, final double min, final double max) {

    Set<Tuple> mostViewed = redisTemplate.execute(new RedisCallback<Set<Tuple>>() {

        @Override

        public Set<Tuple> doInRedis(RedisConnection con)

                throws DataAccessException {

            Set<Tuple> zRangeByScoreWithScore = con.zRangeByScoreWithScores(set.getBytes(), min, max);

            return zRangeByScoreWithScore;

        }

    }); 

    Map<String, Double> mScoreMap = new HashMap<String, Double>(); 

    for (Tuple t : mostViewed) {

        mScoreMap.put(new String(t.getValue()), t.getScore());

    }

    return mScoreMap;

}

My JEDIS configuration:

@Bean

public JedisPoolConfig jedisPoolConfig() {

    JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();

    jedisPoolConfig.setMaxTotal(10);

    jedisPoolConfig.setMaxIdle(5);

    jedisPoolConfig.setMinIdle(2);

    jedisPoolConfig.setTestOnBorrow(true);

    jedisPoolConfig.setTestOnReturn(true);

    jedisPoolConfig.setMaxWaitMillis(3000);

    jedisPoolConfig.setTimeBetweenEvictionRunsMillis(60000);

    return jedisPoolConfig;

}



@Bean

public JedisConnectionFactory jedisConnectionFactory() {



    RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration("localhost", 6379);



    JedisClientConfigurationBuilder jedisClientConfiguration = JedisClientConfiguration.builder();

    jedisClientConfiguration.connectTimeout(Duration.ofSeconds(60));// 60s connection timeout

    jedisClientConfiguration.usePooling();



    JedisConnectionFactory jedisConFactory = new JedisConnectionFactory(redisStandaloneConfiguration,

            jedisClientConfiguration.build());



    return jedisConFactory;

}



@Bean

public StringRedisSerializer stringRedisSerializer() {

    StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

    return stringRedisSerializer;

}



@Bean

RedisTemplate<String, String> redisTemplate() {

    final RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();

    redisTemplate.setConnectionFactory(jedisConnectionFactory());

    redisTemplate.setDefaultSerializer(stringRedisSerializer());

    redisTemplate.setKeySerializer(stringRedisSerializer());

    redisTemplate.setHashKeySerializer(stringRedisSerializer());

    redisTemplate.setEnableTransactionSupport(true);

    return redisTemplate;

}

but, after about 1-2 minutes, my application freeze, with this message in log file (Eclipse log):

[http-nio-8080-exec-9] DEBUG o.s.d.r.core.RedisConnectionUtils - Opening RedisConnection

redis server log (refresh application in web browser has no effect, there are no new messages):

when I stop and start server (Tomcat 8.0.41) in Eclipse everything is OK for 1-2 minutes. When I stop and start REDIS server has no effect.
