Jedis,无法获取jedis连接:无法从池获取资源
我已经在几个线程中看到了答案,但对我却没有解决,而且由于我的问题偶尔发生,因此问这个问题是否有人有任何想法。
我正在使用jedis版本2.8.0,Spring Data Redis版本1.7.5。和redis服务器版本2.8.4用于我们的缓存应用程序。
我有多个缓存保存在redis中,并且从redis获得请求。我正在使用spring数据redis API保存和获取数据。
所有保存和获取都可以正常工作,但偶尔会遇到以下异常:
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 poolorg.springframework.data.redis.connection.jedis.JedisConnectionFactory.fetchJedisConnector(JedisConnectionFactory.java:198)

org.springframework.data.redis.core.AbstractOperations.execute(AbstractOperations.java:88)
org.springframework.data.redis.core.DefaultHashOperations.get(DefaultHashOperations.java:49)
我的redis配置类:
@Configurationpublic 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<String, Object> redisTemplate() {
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(jedisConnectionFactory());
redisTemplate.setExposeConnection(true);
// No serializer required all serialization done during impl
redisTemplate.setKeySerializer(stringRedisSerializer());
//`redisTemplate.setHashKeySerializer(stringRedisSerializer());
redisTemplate.setHashValueSerializer(new GenericSnappyRedisSerializer());
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
@Bean
public RedisCacheManager cacheManager() {
RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate());
redisCacheManager.setTransactionAware(true);
redisCacheManager.setLoadRemoteCachesOnStartup(true);
redisCacheManager.setUsePrefix(true);
return redisCacheManager;
}
}
有没有人遇到这个问题或对此有任何想法,为什么会发生?
回答:
我从redis.template迁移到了Jedis。为池添加了以下配置(也可以在redis模板中添加),现在看不到任何异常:
jedisPoolConfig.setMaxIdle(30);jedisPoolConfig.setMinIdle(10);
对于redis模板:
jedisConnectionFactory.getPoolConfig().setMaxIdle(30);jedisConnectionFactory.getPoolConfig().setMinIdle(10);
上面相同的配置也可以在redis模板中添加。
