springboot+redis 配置多个dbIndex 遇到Cannot get Jedis connection的问题

import org.springframework.beans.factory.annotation.Value;

import redis.clients.jedis.JedisPoolConfig;



@EnableCaching
@Configuration

    @Value("${redis.pool.max-wait}")
    private int redisPoolMaxWait;

    @Bean

        JedisPoolConfig jedisPoolConfig = new JedisPoolConfig();
        jedisPoolConfig.setMaxIdle(redisPoolMaxIdle);
        jedisPoolConfig.setMinIdle(redisPoolMinIdle);
        jedisPoolConfig.setMaxWaitMillis(redisPoolMaxWait);
        return jedisPoolConfig;
    }
    
    @Bean(name = "cacheRedisTemplate13")
    public RedisTemplate getForeRedisTemplate(){

        JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
        connectionFactory.setPoolConfig(getJedisPoolConfig());
        connectionFactory.setDatabase(dbIndex13);	//此处配置database
        connectionFactory.setHostName(host);
        connectionFactory.setPassword(password);
        connectionFactory.setPort(port);
        connectionFactory.afterPropertiesSet();			//记得添加这行！

        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate(connectionFactory);
        return stringRedisTemplate;
    }

    @Bean(name = "cacheRedisTemplate14")
    public RedisTemplate getRedisTemplateDb14(){

        JedisConnectionFactory connectionFactory = new JedisConnectionFactory();
        connectionFactory.setPoolConfig(getJedisPoolConfig());
        connectionFactory.setDatabase(dbIndex14);
        connectionFactory.setHostName(host);
        connectionFactory.setPassword(password);
        connectionFactory.setPort(port);
        connectionFactory.afterPropertiesSet();

        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate(connectionFactory);
        return stringRedisTemplate;
    }

}

如上，参考网上资料配置了两个redisTemplate

本地测试使用时，正常插入各自对应的dbIndex

当发布到测试环境（Linux）时，只有dbIndex13正常使用，另一个会报错

Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisException: Could not get a resource from the pool
 

并不清楚为何出现此问题，希望有谁能解答。

此后将配置多个dbIndex改为动态切换dbIndex

配置代码同上，只是删除了cacheRedisTemplate14的配置

同时，使用cacheRedisTemplate时

JedisConnectionFactory jedisConnectionFactory = (JedisConnectionFactory) cacheRedisTemplate.getConnectionFactory();
        jedisConnectionFactory.setDatabase(dbIndex13);



JedisConnectionFactory jedisConnectionFactory = (JedisConnectionFactory) cacheRedisTemplate.getConnectionFactory();
        jedisConnectionFactory.setDatabase(dbIndex14);
