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:

 

1.  
   import org.codehaus.jackson.type.TypeReference;
2.  
    
3.  
   import java.util.List;
4.  
    
5.  
   /**
6.  
   * Created by gzy on 2017/11/17 17:16.
7.  
   */
8.  
    
9.  
   public interface JedisClient {
10.  
    String get(String key);
11.  
     
12.  
    <T> T get(String key, TypeReference<T> clazz);
13.  
     
14.  
    <T> T get(String key, Class<T> clazz);
15.  
     
16.  
    String get(String key, int select);
17.  
     
18.  
    void setAndExpire(String key, Object o, int expire);
19.  
     
20.  
    Long rpush(String key, String string);
21.  
     
22.  
    // Long del(String... keys);
23.  
    Long lpush(String key, String string);
24.  
     
25.  
    void set(String key, Object o);
26.  
     
27.  
    String set(String key, String value);
28.  
     
29.  
    String hget(String hkey, String key);
30.  
     
31.  
    long hset(String hkey, String key, String value);
32.  
     
33.  
    long incr(String key);
34.  
     
35.  
    long expire(String key, int second);
36.  
     
37.  
    long ttl(String key);
38.  
     
39.  
    long del(String key);
40.  
     
41.  
    long hdel(String hkey, String key);
42.  
     
43.  
    Boolean exists(String key);
44.  
     
45.  
    Long decr(String key);
46.  
     
47.  
    List<String> brpop(int timeout, String key);
48.  
     
49.  
    }

 

jedisClient实现类JedisClientCluster：

15.  
    @Autowired
16.  
    private JedisClient jedisClient;
17.  
     
18.  
    @Test
19.  
    public void testJCluster() {
20.  
    jedisClient.set("test:phone:" + "11111111","hhha");
21.  
    String result = jedisClient.get("test:phone:" + "11111111")
22.  
    System.out.println("result==="+result)

注意：Redis集群并不支持处理多个keys的命令,因为这需要在不同的节点间移动数据,从而达不到像Redis那样的性能,在高负载的情况下可能会导致不可预料的错误.
