把jedis的版本降低成2.9.1即可，3.1.0版本中没有redis.clients.util.SafeEncoder的类定义

改动前：

    <dependency>
       <groupId>redis.clients</groupId>
       <artifactId>jedis</artifactId>
       <version>3.1.0</version>
    </dependency>

改动后：

   <dependency>
       <groupId>redis.clients</groupId>
       <artifactId>jedis</artifactId>
       <version>2.9.1</version>
   </dependency>
