spring – Jedis,无法获得jedis连接：无法从池中获取资源

我已经看到几个线程中的答案,但没有为我工作,因为偶尔会出现问题,如果有任何人有任何想法,请问这个问题.

我使用的是jedis版本2.8.0,Spring Data redis版本1.7.5.和我们的缓存应用程序的redis服务器版本2.8.4.

我有多个缓存,用redis保存,get请求是从redis完成的.我使用spring数据redis API来保存和获取数据.

所有保存和获取工作正常,但偶尔低于例外：

Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool | org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the poolorg.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

org.springframework.data.redis.core.DefaultHashOperations.get(DefaultHashOperations.java:49)

我的redis配置类：

@Configuration
public class RedisConfiguration {

@Value("${redisCentralCachingURL}")
private String redisHost;

@Value("${redisCentralCachingPort}")
private int redisPort;

@Bean
public StringRedisSerializer stringRedisSerializer() {
  StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
  return stringRedisSerializer;
}

@Bean
JedisConnectionFactory jedisConnectionFactory() {
  JedisConnectionFactory factory = new JedisConnectionFactory();
  factory.setHostName(redisHost);
  factory.setPort(redisPort);
  factory.setUsePool(true);
  return factory;
}

@Bean
public RedisTemplate
