redis-Jedis链接集群

关闭防火墙或把端口加入防火墙

1、经过代码

@Test
public void testJedisCluster() throws Exception {
    //建立一链接，JedisCluster对象,在系统中是单例存在
    Set<HostAndPort> nodes = new HashSet<>();
    nodes.add(new HostAndPort("127.0.0.1", 7001));
    nodes.add(new HostAndPort("127.0.0.1", 7002));
    nodes.add(new HostAndPort("127.0.0.1", 7003));
    nodes.add(new HostAndPort("127.0.0.1", 7004));
    nodes.add(new HostAndPort("127.0.0.1", 7005));
    nodes.add(new HostAndPort("127.0.0.1", 7006));
    JedisCluster cluster = new JedisCluster(nodes);
    //执行JedisCluster对象中的方法，方法和redis一一对应。
    cluster.set("cluster-test", "my jedis cluster test");
    String result = cluster.get("cluster-test");
    System.out.println(result);
    //程序结束时须要关闭JedisCluster对象
    cluster.close();
}

 

2、经过spring（ioc控制反转）

一、配置XXX.xml

<!-- redis集群 -->
<bean id="jedisCluster" class="redis.clients.jedis.JedisCluster">
    <constructor-arg index="0">
        <set>
            <bean class="redis.clients.jedis.HostAndPort">
                <constructor-arg index="0" value="192.168.101.3"></constructor-arg>
                <constructor-arg index="1" value="7001"></constructor-arg>
            </bean>
            <bean class="redis.clients.jedis.HostAndPort">
                <constructor-arg index="0" value="192.168.101.3"></constructor-arg>
                <constructor-arg index="1" value="7002"></constructor-arg>
            </bean>
            <bean class="redis.clients.jedis.HostAndPort">
                <constructor-arg index="0" value="192.168.101.3"></constructor-arg>
                <constructor-arg index="1" value="7003"></constructor-arg>
            </bean>
            <bean class="redis.clients.jedis.HostAndPort">
                <constructor-arg index="0" value="192.168.101.3"></constructor-arg>
                <constructor-arg index="1" value="7004"></constructor-arg>
            </bean>
            <bean class="redis.clients.jedis.HostAndPort">
                <constructor-arg index="0" value="192.168.101.3"></constructor-arg>
                <constructor-arg index="1" value="7005"></constructor-arg>
            </bean>
            <bean class="redis.clients.jedis.HostAndPort">
                <constructor-arg index="0" value="192.168.101.3"></constructor-arg>
                <constructor-arg index="1" value="7006"></constructor-arg>
            </bean>
        </set>
    </constructor-arg>
    <constructor-arg index="1" ref="jedisPoolConfig"></constructor-arg>
</bean>

二、测试代码

private ApplicationContext applicationContext;
    @Before
    public void init() {
        applicationContext = new ClassPathXmlApplicationContext(
                "classpath:applicationContext.xml");
    }

    // redis集群
    @Test
    public void testJedisCluster() {
        JedisCluster jedisCluster = (JedisCluster) applicationContext
                .getBean("jedisCluster");
        jedisCluster.set("name", "zhangsan");
        String value = jedisCluster.get("name");
        System.out.println(value);
    }
