使用Jedis连接Redis

使用Jedis连接redis跟我们使用jdbc连接数据库特别向，话不多说，直接上代码。

需要引入的jar包

这里我建的是maven工程，pom坐标配置如下

		<dependency>
	    	<groupId>redis.clients</groupId>
	    	<artifactId>jedis</artifactId>
	    	<version>2.7.0</version>
		</dependency>

代码

package com.taotao.rest.jedis;

import java.util.HashSet;

import javax.swing.Spring;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.taotao.rest.dao.JedisClient;

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

public class JedisTest {

	//单实例链接测试
	@Test
	public void  testJedisSingel() {
		//创建jedis对象
		Jedis jedis=new Jedis("192.168.154.128",6379);
		//调用jedis对象方法，方法名和Jedis命令一致
		jedis.set("key1", "jedis test");
		String string=jedis.get("key1");
		System.out.println(string);
	}

	//使用连接池连接测试
	@Test
	public void testJedisPool() {
		//创建Jedis链接池
		JedisPool pool=new JedisPool("192.168.154.128",6379);
		//从连接池中获得Jedis对象
		Jedis jedis=pool.getResource();
		String string=jedis.get("key1");
		System.out.println(string);
		jedis.close();
		pool.close();
	}

	//集群版链接测试
	@Test
	public void testJedisCluster() {
		HashSet<HostAndPort> nodes=new HashSet<>();
		nodes.add(new HostAndPort("192.168.154.128",6379));
		nodes.add(new HostAndPort("192.168.154.128",6380));
		nodes.add(new HostAndPort("192.168.154.128",6381));
		nodes.add(new HostAndPort("192.168.154.128",6382));
		nodes.add(new HostAndPort("192.168.154.128",6383));
		nodes.add(new HostAndPort("192.168.154.128",6384));
		JedisCluster cluster=new JedisCluster(nodes);

		cluster.set("key1", "test");
		String string=cluster.get("key1");
		System.out.println(string);
		cluster.close();
	}

	//spring整合单机版测试
	@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();
	}

	//spring整合集群版测试
	@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();
	}
