redis集群、單機版本與spring整合步驟

1.搭建集群，關閉虛擬機防火牆，或者iptables參數，允許redis集群端口通過 

service iptables stop 或者 vim /etc/sysconfig/iptables

2.測試集群（不整合spring）

@Test
    public void testJedisCluster(){
        HashSet<HostAndPort> nodes = new HashSet<HostAndPort>();
        nodes.add(new HostAndPort("192.168.31.100", 7001));
        nodes.add(new HostAndPort("192.168.31.100", 7002));
        nodes.add(new HostAndPort("192.168.31.100", 7003));
        nodes.add(new HostAndPort("192.168.31.100", 7004));
        nodes.add(new HostAndPort("192.168.31.100", 7005));
        nodes.add(new HostAndPort("192.168.31.100", 7006));
        JedisCluster cluster = new JedisCluster(nodes);
        cluster.set("key1", "1000");
        System.out.println(cluster.get("key1"));
        cluster.close();
    
    }

 

3.配置spring文件

　　

<bean id="redisClient" class="redis.clients.jedis.JedisCluster">
        <constructor-arg name="nodes">
            <set>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
                    <constructor-arg name="port" value="7001"></constructor-arg>
                </bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
                    <constructor-arg name="port" value="7002"></constructor-arg>
                </bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
                    <constructor-arg name="port" value="7003"></constructor-arg>
                </bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
                    <constructor-arg name="port" value="7004"></constructor-arg>
                </bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
                    <constructor-arg name="port" value="7005"></constructor-arg>
                </bean>
                <bean class="redis.clients.jedis.HostAndPort">
                    <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
                    <constructor-arg name="port" value="7006"></constructor-arg>
                </bean>
            </set>
        </constructor-arg>
　　　　　　<!-- 可省略 -->
        <constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg>  
    </bean>

<!-- 連接池配置 -->
    <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
        <!-- 最大連接數 -->
        <property name="maxTotal" value="30" />
        <!-- 最大空閑連接數 -->
        <property name="maxIdle" value="10" />
        <!-- 每次釋放連接的最大數目 -->
        <property name="numTestsPerEvictionRun" value="1024" />
        <!-- 釋放連接的掃描間隔（毫秒） -->
        <property name="timeBetweenEvictionRunsMillis" value="30000" />
        <!-- 連接最小空閑時間 -->
        <property name="minEvictableIdleTimeMillis" value="1800000" />
        <!-- 連接空閑多久后釋放, 當空閑時間>該值 且 空閑連接>最大空閑連接數 時直接釋放 -->
        <property name="softMinEvictableIdleTimeMillis" value="10000" />
        <!-- 獲取連接時的最大等待毫秒數,小於零:阻塞不確定的時間,默認-1 -->
        <property name="maxWaitMillis" value="1500" />
        <!-- 在獲取連接的時候檢查有效性, 默認false -->
        <property name="testOnBorrow" value="true" />
        <!-- 在空閑時檢查有效性, 默認false -->
        <property name="testWhileIdle" value="true" />
        <!-- 連接耗盡時是否阻塞, false報異常,ture阻塞直到超時, 默認true -->
        <property name="blockWhenExhausted" value="false" />
    </bean>

4.測試集群（整合spring）

@Test
    public void testSpringJedisCluster() {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-*.xml");
        JedisCluster jedisCluster =  (JedisCluster) applicationContext.getBean("redisClient");
        String string = jedisCluster.get("key1");
        System.out.println(string);
        jedisCluster.close();
    }

 5.單擊版本測試（不整合spring）

@Test
    public void testJedisSingle(){
        //創建一個jedis的對象
        Jedis jedis = new Jedis("192.168.31.100", 6379);
        //調用jedis對象的方法，方法名稱和redis的命令一致
        jedis.set("key1", "test01");
        System.out.println(jedis.get("key1"));
        //關閉jedis
        
        jedis.close();
    }

 

6.單擊版本spring配置

<!-- jedis客戶端單機版 -->
    <bean id="redisClient" class="redis.clients.jedis.JedisPool">
        <constructor-arg name="host" value="192.168.31.100"></constructor-arg>
        <constructor-arg name="port" value="6379"></constructor-arg>
        <constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg>
    </bean>

 

7.單擊版本spring（整合測試）

@Test
    public void testSpringJedisSingle() {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-*.xml");
        JedisPool pool = (JedisPool) applicationContext.getBean("redisClient");
        Jedis jedis = pool.getResource();
        String string = jedis.get("key1");
        System.out.println(string);
        jedis.close();
        pool.close();
    }
