Jedis基本操作

Jedis可以使redis的一系列操作在java中进行

首先配置端口号及ip地址（注：需要远程连接需要修改redis中的配置文件，以及开放端口）

//创建Jedis对象
Jedis jedis=new Jedis("192.168.89.131",6379);

String操作：

//    操作String
    @Test
    public void demo1(){
        //创建Jedis对象
        Jedis jedis=new Jedis("192.168.89.131",6379);


        //设置多个key-value
        jedis.mset("k1","v1","k2","v2");
        List<String> mget=jedis.mget("k1","k2");
        System.out.println(mget);
        Set<String> keys=jedis.keys("*");
        for (String key:keys){
            System.out.println(key);
        }
    }

打印结果：

[v1, v2]
name
key1
names
china
k1
k2

操作List：

    //操作lsit
    @Test
    public void demo2(){
        //创建Jedis对象
        Jedis jedis=new Jedis("192.168.89.131",6379);
        jedis.lpush("key1", "lucy","mary","jack");
        List<String> values=jedis.lrange("key1", 0, -1);
        System.out.println(values);
    }

打印结果：

[jack, mary, lucy]

Process finished with exit code 0

操作set

    @Test
    public void demo3(){
        //创建Jedis对象
        Jedis jedis=new Jedis("192.168.89.131",6379);
        jedis.sadd("names", "lucy");
        jedis.sadd("names", "jack");
        Set<String> names=jedis.smembers("names");
        System.out.println(names);
    }

打印结果:

[jack, lucy]

Process finished with exit code 0

操作Hash：

    @Test
    public void demo4(){
        //创建Jedis对象
        Jedis jedis=new Jedis("192.168.89.131",6379);
        jedis.hset("users", "age", "20");
        String hget=jedis.hget("users", "age");
        System.out.println(hget);
    }

打印结果：

20

Process finished with exit code 0

操作zset：

    @Test
    public void demo5(){
        //创建Jedis对象
        Jedis jedis=new Jedis("192.168.89.131",6379);
        jedis.zadd("china", 100d, "shanghai");
        Set<String> china=jedis.zrange("china", 0, -1);
        System.out.println(china);
    }

打印结果：

[shanghai]
