java链接redis

redis支持那些语言可以操作：

找到客户端点进去: 

 

1.使用jedis

1.1 添加jedis依赖

1.2 代码测试

@Test
    public void test01(){
        //连接redis--->必须保证你的redis服务运行远程连接。
        //该对象中把每个redis命令封装成对应的方法了。
        Jedis jedis=new Jedis("192.168.223.155",6380);
        //对于字符串操作的命令
        String s = jedis.set("k1", "v1");
        System.out.println(s);
        String setex = jedis.setex("k2", 30l, "v2");
        System.out.println(setex);
        Long aLong = jedis.setnx("k3", "v11");
        System.out.println(aLong);
 
        //对于hash操作
        jedis.hset("k4","name","刘德华");
        jedis.hset("k4","age","15");
 
        Map map=new HashMap();
        map.put("name","张需要");
        map.put("age","28");
        jedis.hset("k5",map);
 
 
        jedis.close();
 
    }

 1.3 javalianjie redis集群模式

 @Test
    public void test03(){
        Set nodes=new HashSet<>();
        nodes.add(new HostAndPort("192.168.223.155",6001));
        nodes.add(new HostAndPort("192.168.223.155",6002));
        nodes.add(new HostAndPort("192.168.223.155",6003));
        nodes.add(new HostAndPort("192.168.223.155",6004));
        nodes.add(new HostAndPort("192.168.223.155",6005));
        nodes.add(new HostAndPort("192.168.223.155",6006));
        JedisCluster jedisCluster=new JedisCluster(nodes);
 
        jedisCluster.set("k6","刘德华和闫克起");
 
        jedisCluster.close();
 
    }
