创建cache.properties:

 

redis.host =192.168.xx.xxx
redis.port1=7001

redis.port2=7002

redis.port3=7003

redis.port4=7004

redis.port5=7005

redis.port6=7006

redis.clusterpassword=xxxxxxx

 

 

创建接口JedisClient:

   import java.util.List;

   public interface JedisClient {

    String get(String key);
11.  
     
12.  
    <T> T get(String key, TypeReference<T> clazz);
13.  
     
14.

16.  
    String get(String key, int select);

18.  
    void setAndExpire(String key, Object o, int expire);
19.  
     
20.  
    Long rpush(String key, String string);
21.

    // Long del(String... keys);
23.  
    Long lpush(String key, String string);
