Redis使用初步

学习的时候先在Windows进行

下载:https://github.com/MicrosoftArchive/redis/releases

Redis-x64-3.2.100.msi

按照默认安装,

 

启动redis服务器命令

cd 到redis安装目录,redis-server redis.windows.conf

作为服务安装 redis-server --service -install redis.windows.conf

 

使用redis客户端存储和读取键值对

redis-cli.exe -h 127.0.0.1 -p 6379 

set hi " good to know you"

get hi

系统就返回“good to know you”字符串

 

Java 中使用Redis

把Jedis的maven配置

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>

写到maven工程的pom.xml文件中。

示例:

Jedis测试代码

import redis.clients.jedis.Jedis;

public class MainFIle {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Jedis jd=new Jedis("127.0.0.1");
        System.out.println("当前Redis服务状态"+jd.ping());
        jd.set("hi", "nice to meet you");
        System.out.println("value of hi is "+jd.get("hi"));
     jd.close(); } }

 

使用连接池

    /**
     * 使用连接池
     */
    @Test
    public void testJedisPool() {
        //创建jedis连接池
        JedisPool pool = new JedisPool("192.168.25.153", 6379);
        //从连接池中获得Jedis对象
        Jedis jedis = pool.getResource();
        String string = jedis.get("key1");
        System.out.println(string);
        //关闭jedis对象
        jedis.close();
        pool.close();
    }

集群测试

@Test
    public void testJedisCluster() {
        HashSet<HostAndPort> nodes = new HashSet<>();
        nodes.add(new HostAndPort("192.168.25.153", 7001));
        nodes.add(new HostAndPort("192.168.25.153", 7002));
        nodes.add(new HostAndPort("192.168.25.153", 7003));
        nodes.add(new HostAndPort("192.168.25.153", 7004));
        nodes.add(new HostAndPort("192.168.25.153", 7005));
        nodes.add(new HostAndPort("192.168.25.153", 7006));
        
        JedisCluster cluster = new JedisCluster(nodes);
        
        cluster.set("key1", "1000");
        String string = cluster.get("key1");
        System.out.println(string);
        
        cluster.close();
    }
