测试：

@Test
    public void test(){
        //创建一个jedis的连接
        Jedis jedis=new Jedis("127.0.0.1",6379);
        //执行redis命令
        jedis.set("mytest","test success");
        //从redis中取值
        String result=jedis.get("mytest");
        //打印结果
        System.out.println(result);
        //关闭链接
        jedis.close();
    }

@Test
    public void testJedis(){
        Jedis jedis=new Jedis("127.0.0.1",6379);
        jedis.set("java","100");//设置一个String类型的key
        System.out.println(jedis.get("java"));//读取java类型的key


        Map<String,String> stuinfo=new HashMap<>();
        stuinfo.put("sid","100");
        stuinfo.put("sname","老白");
        stuinfo.put("class","三班");
        jedis.hmset("stuinfo",stuinfo);//
        Map<String,String> map=jedis.hgetAll("stuinfo");
        System.out.println(map);
        System.out.println(stuinfo==map);//内存不相等

        Map<String,Double> saleCount=new HashMap<>();
        saleCount.put("苹果",34.0);
        saleCount.put("香蕉",79.0);
        jedis.zadd("salecount",saleCount);
        Set<String> resultl=jedis.zrange("salecount",0,-1);
        System.out.println(resultl);
        jedis.close();
    }

jedis操作对象数据

 @Test  //测试对象的读写
    public void testObject(){
        //创建一连接池对象
        JedisPool jedisPool = new JedisPool("127.0.0.1", 6379);
        //从连接池中获取一条连接。
        Jedis jedis = jedisPool.getResource();
        Book b1 = new Book();
        b1.setBid(1);
        b1.setBname("西游记");
        //存储
        jedis.hset("b1","bid",b1.getBid()+"");
        jedis.hset("b1","bname",b1.getBname()+"");
        Book b2 = new Book();
        //读取
        b2.setBid(Integer.parseInt(jedis.hget("b1","bid")));
        b2.setBname(jedis.hget("b1","bname"));
        System.out.println(b2);
        Student student = new Student();
        student.setSid(1);
        student.setSname("老白");
        student.setAge(18);
        student.setBook(b1);//持有关联对象
        Gson gson = new Gson();
        String json = gson.toJson(student);//转成json字符串
        jedis.set("stu",json);//存储json字符串
        String json2 = jedis.get("stu");//读取json字符串
        //重新构造对象
        Student student2 = gson.fromJson(json2,Student.class);
        System.out.println(student2);
        jedis.close();//归还连接池
        jedisPool.close();//关闭连接池
    }
