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：

 

1.   /**
2.   * Created by gzy on 2017/11/17 17:17.
3.   */
4.    
5.   import org.codehaus.jackson.type.TypeReference;
6.   import com.thinkgem.jeesite.common.utils.StringUtils;
7.   import org.springframework.beans.factory.annotation.Autowired;
8.    
9.   import redis.clients.jedis.JedisCluster;
10.    
11.   import java.util.List;
12.    
13.   public class JedisClientCluster implements JedisClient {
14.    
15.   @Autowired
16.   private JedisCluster jedisCluster;
17.    
18.   public <T> T get(String key, TypeReference<T> clazz) {
19.   String json = jedisCluster.get(key);
20.   if (StringUtils.isNotEmpty(json)) {
21.   return JsonUtil.Json2Object(json, clazz);
22.   } else {
23.   return null;
24.   }
25.   }
26.    
27.   public <T> T get(String key, Class<T> clazz) {
28.   String json = jedisCluster.get(key);
29.   if (StringUtils.isNotEmpty(json)) {
30.   return JsonUtil.Json2Object(json, clazz);
31.   } else {
32.   return null;
33.   }
34.   }
35.    
36.   public void set(String key, Object o) {
37.   String json = JsonUtil.Object2Json(o);
38.   jedisCluster.set(key, json);
39.   }
40.    
41.   public void setAndExpire(String key, Object o, int expire) {
42.   String json = JsonUtil.Object2Json(o);
43.   jedisCluster.set(key, json);
44.   jedisCluster.expire(key, expire);
45.   }
46.    
47.   // public long del(String key) {
48.   // return jedisCluster.del(key);
49.   // }
50.    
51.   public String get(String key) {
52.   return jedisCluster.get(key);
53.   }
54.    
55.   public String get(String key, int select) {
56.   jedisCluster.select(select);
57.   return jedisCluster.get(key);
58.   }
59.    
60.   @Override
61.   public String set(String key, String value) {
62.   return jedisCluster.set(key, value);
63.   }
64.    
65.   @Override
66.   public String hget(String hkey, String key) {
67.   return jedisCluster.hget(hkey, key);
68.   }
69.    
70.   @Override
71.   public long hset(String hkey, String key, String value) {
72.   return jedisCluster.hset(hkey, key, value);
73.   }
74.    
75.   @Override
76.   public long incr(String key) {
77.   return jedisCluster.incr(key);
78.   }
79.    
80.   public Long decr(String key) {
81.   return jedisCluster.decr(key);
82.   }
83.    
84.   @Override
85.   public long expire(String key, int second) {
86.   return jedisCluster.expire(key, second);
87.   }
88.    
89.   @Override
90.   public long ttl(String key) {
91.   return jedisCluster.ttl(key);
92.   }
93.    
94.   @Override
95.   public long del(String key) {
96.   return jedisCluster.del(key);
97.   }
98.    
99.   @Override
100.   public long hdel(String hkey, String key) {
101.    
102.   return jedisCluster.hdel(hkey, key);
103.   }
104.    
105.   public Long rpush(String key, String string) {
106.   return jedisCluster.rpush(key, string);
107.   }
108.    
109.   public Long lpush(String key, String string) {
110.   return jedisCluster.lpush(key, string);
111.   }
112.    
113.   public Boolean exists(String key) {
114.   return jedisCluster.exists(key);
115.   }
116.    
117.   public List<String> brpop(int timeout, String key) {
118.   return jedisCluster.brpop(timeout, key);
119.   }
120.    
121.   }

 

 

创建测试类ClusterTest:

 

1.   import xx.xx.xxx.xxxx.JedisClient;
2.   import org.junit.Test;
3.   import org.junit.runner.RunWith;
4.   import org.springframework.beans.factory.annotation.Autowired;
5.   import org.springframework.test.context.ContextConfiguration;
6.   import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
7.    
8.   /**
9.   * Created by gzy on 2017/11/20 15:22.
10.   */
11.   @RunWith(SpringJUnit4ClassRunner.class)
12.   @ContextConfiguration("classpath:spring-context-cache.xml")
13.   public class ClusterTest {
14.   // private static JedisClientCluster redisCluster = SpringContextHolder.getBean("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)
23.    
24.   }}
