Question

我试图用spring Boot实现redis，我在本地主机上随机遇到下面的异常：

redis.clients.jedis.exceptions.JedisConnectionException：无法获取来自池的资源;

我已经尝试过JedisPoolConfig的各种属性组合。但他们都没有帮助不确定哪里出错了。

@Configuration
public class RedisConfigurationSetup {    
    @Bean
    public RedisConnectionFactory jedisConnectionFactory() {
        JedisPoolConfig poolConfig = new JedisPoolConfig();
        poolConfig.setMaxTotal(10000);
        poolConfig.setMinIdle(1000);
        poolConfig.setMaxIdle(-1);
        poolConfig.setMaxWaitMillis(500);
        poolConfig.setTestOnBorrow(true);
        poolConfig.setTestOnReturn(true);
        JedisConnectionFactory ob = new JedisConnectionFactory(poolConfig);
        ob.setHostName("127.0.0.1");
        ob.setPort(6379);
        ob.setUsePool(true);
        return ob;
    }

    @SuppressWarnings({ "rawtypes" })
    @Bean(name = "redisTemplate")
    public RedisTemplate stringRedisTemplate() {
        RedisTemplate rt = new RedisTemplate();
        rt.setConnectionFactory(jedisConnectionFactory());
        rt.setEnableTransactionSupport(true);
        return rt;
    }
}


public class GeoLocationCacheServiceImpl implements GeoLocationCacheService {

    @Autowired
    @Qualifier("redisTemplate")
    RedisTemplate geoObjectRedisTemplate;

    @Override
    public void saveUpdateGeoLoc(GeoObject geoObject) {

        if (geoObject != null) {
            // Some Business logics 
            geoObjectRedisTemplate.opsForValue().set(geoObject.getObjectID(), geoObject);
            // Some Business logics 
        }
    }
}

因为rt.setEnableTransactionSupport（true）; 从源代码中，我们可以看到

if (!enableTransactionSupport) {
            RedisConnectionUtils.releaseConnection(conn, factory);
        }
