我正在創建Web應用程序並使用Redis進行數據存儲。 我已經使用JedisPoolConfig(redis client-jedis版本2.9.0)。 所以,當我測試我使用Apache的JMeter的幫助應用程序與以下配置:無法獲取Jedis連接,無法從池中獲取資源
Number of threads(Users): 30
Ramp-Up period(in seconds) : 0
Loop-Count : 1
和JedisPoolConfig具有以下配置:
redis.sentinel.enable=true
redis.sentinel.ip=localhost
redis.sentinel.port=6379
redis.instance.account.masterName=master
redis.pool.max-active = 20
redis.pool.max-idle = 10
與此代碼(這是因爲豆上創建Spring應用程序的啓動):
JedisConnectionFactory factory = new JedisConnectionFactory();
factory.setPort(port);
factory.setHostName(hostName);
factory.afterPropertiesSet();
factory.setUsePool(true);
JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
jedisPoolConfig.setMaxTotal(redisPoolMaxActive);
jedisPoolConfig.setMaxIdle(redisPoolMaxIdle);
factory.setPoolConfig(jedisPoolConfig);
return factory;
與此代碼每次取新連接的請求來了:
@Autowired
private JedisConnectionFactory redisConnectionFactory;
private StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
private RedisTemplate getNewConnection(){
RedisTemplate redisTemplate = new RedisTemplate();
redisTemplate.setConnectionFactory(redisConnectionFactory);
redisTemplate.setKeySerializer(stringRedisSerializer);
redisTemplate.setHashKeySerializer(stringRedisSerializer);
redisTemplate.setValueSerializer(stringRedisSerializer);
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
編輯:我使用的redisTemplate多/ EXEC內的Redis:
redisTemplate.setEnableTransactionSupport(true);
redisTemplate.multi();
for (ArrayList<Pair<String, String>> pairs : keys){
for (Pair<String,String> pair: pairs)
redisTemplate.opsForHash().get(makeMap(pair.getFirst(), version) , pair.getSecond());
}
return redisTemplate.exec();
我順利拿到了20個請求的響應,但不能得到休息10所請求的響應。我現在面臨的問題是,經過20個連接已經使用了前20條的要求,其餘10個請求無法從池中獲取的jedis連接,因此我得到以下異常:

我已搜查通過網絡,但無法找到解決方案。有誰能夠幫助我?
請發佈完整的堆棧跟蹤,因爲它是從你的應用程序。 – mp911de
@ mp911de,我編輯了完整的例外。 –
我也在網上找到了這個配置:jedisPoolConfig.getBlockWhenExhausted();這個參數是通過deault來實現的。但似乎jedispoolconfig實際上並沒有阻止所有連接使用中的請求。 –
