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

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);

最后
