spring-data-redis使用cluster失败

Question

错误信息如下：
Caused by: org.springframework.data.redis.RedisConnectionFailureException: Could not get a resource from the pool; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

代码如下：
RedisClusterConfig.class

@Configuration
public class RedisClusterConfig {
    @Bean
    RedisClusterConfiguration redisClusterConfiguration(){
        List<String> nodes = new ArrayList<>();
        nodes.add("192.168.145.141:7001");nodes.add("192.168.145.141:7002");nodes.add("192.168.145.141:7003");
        nodes.add("192.168.145.141:7004");nodes.add("192.168.145.141:7005");nodes.add("192.168.145.141:7006");
        RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(nodes);
        return redisClusterConfiguration;
    }
    @Bean("redisConnectionFactory")
    JedisConnectionFactory redisConnectionFactory(){
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisClusterConfiguration());
        return jedisConnectionFactory;
    }
    @Bean("redisCacheManager")
    public RedisCacheManager redisCacheManager() {
        return RedisCacheManager.create(redisConnectionFactory());
    }
}

DemoApplication.class

@SpringBootApplication
public class DemoApplication {
   public static void main(String[] args) {
      SpringApplication.run(DemoApplication.class, args);
   }
   @Bean
   public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
      return args -> {
         System.out.println("Let's inspect the beans provided by Spring Boot:");
         String[] beanNames = ctx.getBeanDefinitionNames();
         Arrays.sort(beanNames);
         for (String beanName : beanNames) {
            System.out.println(beanName);
         }
         RedisConnectionFactory redisConnectionFactory = (RedisConnectionFactory)ctx.getBean("redisConnectionFactory");
         RedisCacheManager redisCacheManager = (RedisCacheManager)ctx.getBean("redisCacheManager");
         Cache cache = redisCacheManager.getCache("abc");
         if(cache != null){
            cache.put("13",13);
            String a = cache.get("13").toString();
            System.out.println("a is " + a);
         }else {
            System.out.println("can not find cache");
         }
      };
   }
}

我调试发现配置有问题：

pom信息如下：

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>

Answer 1

  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
        <version>2.1.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
        <version>2.9.0</version>
    </dependency>

这两依赖为啥需要单独引入？
data-redis不要声明版本，parent-starter已经声明了，下面的jedis更不需要了，
