我在春季启动时遇到了一个初始化Jedis池子类bean的异常

Question

我想在Spring boot（1.5.14）中初始化Jedis池bean，如果配置了sentinel，它应该返回JedisSentinelPool；否则返回JedisPool。

所以我的代码在这里：

@Resource
private RedisProperties redisProperties;

@Bean(destroyMethod = "close")
public Pool<Jedis> jedisPool(JedisConnectionFactory conn) {
    if (conn.isRedisSentinelAware()) {
        return getJedisSentinelPool(conn);
    } else {
        return getJedisPool(conn);
    }
}

private JedisPool getJedisPool(JedisConnectionFactory conn) {
    if (StringUtils.isEmpty(conn.getPassword())) {
        return new JedisPool(conn.getPoolConfig(), conn.getHostName(), conn.getPort(), conn.getTimeout());
    } else {
        return new JedisPool(conn.getPoolConfig(), conn.getHostName(), conn.getPort(), conn.getTimeout(), conn.getPassword());
    }
}

private JedisSentinelPool getJedisSentinelPool(JedisConnectionFactory conn) {
    Set<String> sentinels = new HashSet<>(asList(redisProperties.getSentinel().getNodes().split(",")));
    if (StringUtils.isEmpty(conn.getPassword())) {
        return new JedisSentinelPool(redisProperties.getSentinel().getMaster(), sentinels, conn.getPoolConfig(), conn.getTimeout());
    } else {
        return new JedisSentinelPool(redisProperties.getSentinel().getMaster(), sentinels, conn.getPoolConfig(), conn.getTimeout(), conn.getPassword());
    }
}

返回JedisPool时，一切都很好；但是如果返回JedisSentinelPool，则会出现此异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.imlht.springboot.dubbo.provider.RedisTest': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'jedisPool' is expected to be of type 'redis.clients.jedis.JedisPool' but was actually of type 'redis.clients.jedis.JedisSentinelPool'

JedisSentinelPool和JedisPool都是Pool的子类，为什么JedisSentinelPool有这样的例外？我该如何解决？非常感谢！
