上一節我記錄瞭如何搭建redis官方的叢集，這節我就開始講怎麼用jedis實現叢集環境下的客戶端。
jedis中實現叢集的客戶端類是redis.clients.jedis.JedisCluster，裡面有好多個構造方法，上一節中我們搭建的叢集環境是有密碼的，所以我用了這個構造方法

public JedisCluster(Set<HostAndPort> jedisClusterNode, int connectionTimeout, int soTimeout,
                      int maxAttempts, String password, final
 
 GenericObjectPoolConfig poolConfig) {
    super(jedisClusterNode, connectionTimeout, soTimeout, maxAttempts, password, poolConfig);
  }

接下來就是spring的配置了

 <context:property-placeholder location="classpath:redisConfig.properties" />

    <bean id="poolConfig" class="redis.clients.jedis.JedisPoolConfig"
 
 >
        <!--最大空閒數-->
        <property name="maxIdle" value="${redis.maxIdle}" />
        <!--連線池的最大資料庫連線數  -->
        <property name="maxTotal" value="${redis.maxTotal}" />
        <!--最大建立連線等待時間-->
        <property name="maxWaitMillis" value="${redis.maxWaitMillis}"
 
 />
        <!--逐出連線的最小空閒時間 預設1800000毫秒(30分鐘)-->
        <property name="minEvictableIdleTimeMillis" value="${redis.minEvictableIdleTimeMillis}" />
        <!--每次逐出檢查時 逐出的最大數目 如果為負數就是 : 1/abs(n), 預設3-->
        <property name="numTestsPerEvictionRun" value="${redis.numTestsPerEvictionRun}" />
        <!--逐出掃描的時間間隔(毫秒) 如果為負數,則不執行逐出執行緒, 預設-1-->
        <property name="timeBetweenEvictionRunsMillis" value="${redis.timeBetweenEvictionRunsMillis}" />
        <!--是否在從池中取出連線前進行檢驗,如果檢驗失敗,則從池中去除連線並嘗試取出另一個-->
        <property name="testOnBorrow" value="${redis.testOnBorrow}" />
        <!--在空閒時檢查有效性, 預設false  -->
        <property name="testWhileIdle" value="${redis.testWhileIdle}" />
    </bean>
<!--redis-cluster配置-->
    <bean id="jedisCluster" class="redis.clients.jedis.JedisCluster">
        <!--此處用的是jedis的其中一個構造方法-->
        <!--JedisCluster(Set<HostAndPort> jedisClusterNode, int connectionTimeout, int soTimeout, int maxAttempts,
         String password, final GenericObjectPoolConfig poolConfig)-->
        <constructor-arg index="0">
            <set>
                <bean class="redis.clients.jedis.HostAndPort">

        <constructor-arg index="4" value="root" />
        <constructor-arg index="5" ref="poolConfig" />
    </bean>

這裡是測試程式碼

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-cache.xml"})
public class RedisTest {
    @Autowired
    JedisCluster jedisCluster;

    @Test
    public void testJedisCluster() {
        System.out.println(jedisCluster.set("test", "test"));
        System.out.println(jedisCluster.get("test"));
        System.out.println(jedisCluster.get("name"));
        System.out.println(jedisCluster.get("age"));
        System.out.println(jedisCluster.get("haha"));
        System.out.println(jedisCluster.get("haha"));
    }
}

注意：我的jedis版本是2.9.0的，spring是4.2.5.RELEASE
