相关依赖包，使用的是springboot 2.3.1

<dependency>
    <groupId>org.apache.dubbo</groupId>

原因： 此类org.apache.dubbo.registry.redis.RedisRegistry中的import redis.clients.util.Pool;包导入有误，应该使用import redis.clients.jedis.util.Pool;l

Please add the dependency : 

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

instead of 

<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo-registry-redis</artifactId>
    <version>2.7.7</version>
</dependency>
