Redis在開發中的使用Jedis：單機版和集羣版

0、添加依賴

        <!-- Redis客戶端 -->
        <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
        </dependency>

一、配置文件：applicationContext-redis.xml

	</bean>

</beans>

二、使用步驟：

package com.e3mall.jedis;

import java.util.HashSet;
import java.util.Set;

import org.junit.Test;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisCluster;
import redis.clients.jedis.JedisPool;

public class TestJedis {
    // 單機版Redis
    @Test
    public void testJedis() {
        // 創建一個連接jedis對象 參數 host,port
        Jedis jedis = new Jedis("192.168.25.130", 6379);
        // 直接使用jedis操作redis。所有jedis命令都對應一個方法
        jedis.set("testJedis", "Hello my first Jedis");
        String string = jedis.get("testJedis");
        System.out.println(string);
        // 關閉jedis
        jedis.close();
    }

    // 單機版Redis 使用連接池單機版的Redis
    @Test
    public void testJedisPool() {
        // 創建連接池對象JedisPool；參數 host,port
        JedisPool jedisPool = new JedisPool("192.168.25.130", 6379);
        // 從連接池中獲取一個連接,就是一個jedis對象
        Jedis jedis = jedisPool.getResource();
        // 使用jedis操作redis
        String string = jedis.get("testJedis");
        System.out.println(string);
        // 關閉連接，每次使用完畢後關閉連接。連接池回收資源
        jedis.close();
        // 關閉連接池jedisPool
        jedisPool.close();
    }

    // 集羣版Redis
    @Test
    public void testJedisCluster() throws Exception {
        // 創建一個JedisCluster對象，有一個參數nodes是一個Set類型。Set中包含若干個HostAndPort對象
        Set<HostAndPort> nodes = new HashSet<HostAndPort>();
        nodes.add(new HostAndPort("192.168.25.130", 7001));
        nodes.add(new HostAndPort("192.168.25.130", 7002));
        nodes.add(new HostAndPort("192.168.25.130", 7003));
        nodes.add(new HostAndPort("192.168.25.130", 7004));
        nodes.add(new HostAndPort("192.168.25.130", 7005));
        nodes.add(new HostAndPort("192.168.25.130", 7006));
        JedisCluster jedisCluster = new JedisCluster(nodes);
        // 直接使用JedisCluster對象操作redis
        jedisCluster.set("testJedisCluster", "Hello My Frist JedisCluster");
        String string = jedisCluster.get("testJedisCluster");
        System.out.println(string);
        // 關閉JedisCluster對象
        jedisCluster.close();
    }
}
