JedisAPI类

连接Redis

public void before(){
        //连接Redis
        jedis=new Jedis("192.168.7.89");
        //设置权限密码
        jedis.auth("redis");
        jedis.ping();
        System.out.println("redis连接成功");
    }

Redis操作String类

@Test
    public void operationString(){
        //切换数据库
        jedis.select(1);
        //设置一个String类型的key-value
        jedis.set("setkey01","strValue01");
        //如何设置key的有效期
        //jedis.exprire("strKey01",20);
        //获取String数据
        String value = jedis.get("strKey01");
        System.out.println("对应存放的value值为："+value);
        //修改数据
        jedis.set("strKey01","strValue");
        //删除数据
        jedis.del("strKey01");
        //设置多个值
        jedis.mset("strKay01","strValue01","strKey02","strValue02","strKey03","strValue03","1");
        //+1操作
        jedis.incr("strKey04");
        //-1操作
        jedis.decr("strKey04");
        //拼接
        jedis.append("strKey04","append");
    }

redis操作list

    @Test
    public void  openrationList(){
        //清空集合
        jedis.del("listkey01","listkey02");
        //设置List集合值，左侧插入
        jedis.lpush("listkey01","张三","李四","王五");
        //设置List集合值，右侧插入
        jedis.rpush("listkey02","北京","上海","广州");
        //获取List集合值
        List<String> listkey01 = jedis.lrange("list可以01",0,-1);
        for (String item:listkey01){
            System.out.println(item);
        }
        //更改List集合数据
        jedis.lset("listkey01",0,"赵六");
    }

redis操作set

@Test
    public void operationSet(){
        //设置Set集合
        jedis.sadd("listkey01","张三","李四","王五");
        //获取
        Set<String> setkey01=jedis.smembers("setkey01");
        for (String item:setkey01){
            System.out.println(item);
        }
    }

redis操作SortedSet

public void openrationSortedSet(){
        //设置SortedSet集合
        jedis.zadd("setKey02",1,"北京");
        jedis.zadd(":setkey02",2,"上海");
        //获取SortedSed
        Set<String> setkey02 = jedis.zrange("setkey02",0,-1);
        for (String item:setkey02){
            System.out.println(item);
        }
    }

redis操作map

@Test
    public void operationMap(){
        //设置Map
        Map<String,String> map=new HashMap<>();
        map.put("name","张三");
        jedis.hmset("mapkey01",map);

        //获取值
        List<String> value = jedis.hmget("mapkey01","name","age");
        for (String item:value){
            System.out.println(item);
        }
